About nbr float sensor

Types Of NBR Float Sensor

NBR sensors are made of a specific material called NBR, which can handle extreme conditions. The sensors help measure levels of liquids in different kinds of tanks. Several types of these sensors work for different purposes.

These include:

  • Radar Sensors

    These sensors nip the liquid level by sending out radar waves from the top of a tank. The waves bounce off the liquid surface and back to the sensor. The sensor then figures out the liquid level by how long it takes the waves to come back. Radar sensors work well in tanks with steam, foam, or anything else that creates mess at the surface, and they also do not touch the liquid.

  • Ultrasonic Sensors

    Ultrasonic sensors measure the distance to the liquid surface using sound waves. They send a sound wave from the top of the tank, and when the wave hits the liquid surface, it bounces back. The sensor then calculates the level based on how long it took the wave to return. These sensors are cheap but do not work well in tanks with dust, steam, or waves on the liquid surface.

  • Magnetostrictive Sensors

    These sensors have a float that moves up and down inside the tank. The sensor sends out a magnetic pulse, which causes a tiny part of the float to move. A small metal piece attached to the float can measure the liquid level very precisely. Since the float does not directly touch the liquid, these sensors work great for measuring levels in tanks without openings. They are used when liquid levels need to be measured very accurately.

  • Capacitive Sensors

    NBR capacitive level sensors measure the distance to the liquid by calculating the electric charge between two electrodes. As the liquid level rises and falls, the charge changes. This sensor can also touch the liquid but is good for simple tasks where high precision is not needed. It is often used for liquids like water and oil, which these sensors can easily detect.

  • Float Switches

    These are simple devices that use a floating ball to open or close a switch and come in two types: single and dual. Single switches turn on or off an electrical device when the float reaches a specific level in the tank. Double switches have two floats: one for turning something on and another for off, allowing control of pumps and alarms. These are cheap switches that provide reliable action at set levels.

Radar NBR Float Sensor Features And Benefits

Features are what a product has, and benefits are what it can do for the user. Radar sensors have features that help them measure liquid levels, and these features provide benefits.

  • High Accuracy

    The main thing these sensors can do is measure levels accurately. When the sensors send back waves, they can measure the level within a tiny gap. This makes them very useful for measuring levels of liquids where one needs to add or take away just a little bit.

  • No Contact Measurement

    These sensors don't touch the liquids to measure them, which is a good thing. They can work well even when the lid is closed or at very high temperatures and pressures. This is helpful because the sensors can measure things without opening the tank or being harmed.

  • Works with Many Liquids

    These sensors can measure a lot of liquids. Simple liquids such as water to thick liquids such as oil or even frothy ones like chemicals. As long as the liquids don't harm the radar waves, they should work fine. This is good because one sensor can measure many different liquids.

  • Strong Build

    These sensors are built very strongly. They are made to keep working even in rough places like hot temperatures, high pressures, or vacuum spaces. This is good because the sensors should not break easily and will keep working no matter where they are.

  • Simple Maintenance

    Since these sensors don't touch the liquids, one does not have to open the tanks or get inside to take care of them. They also don't have any moving parts, which means nothing gets worn out or broken. This makes it easy to keep the sensors working for a long time without much care needed.

Benefits Of NBR Float Sensor

  • Efficient Monitoring: Using these sensors helps keep track of liquid levels automatically. This saves time and prevents overflowing or running out of liquids.
  • Preventing Waste and Damage: The sensors can send alerts when levels get too high or low, helping to stop spills and empty tanks. This protects the area from getting damaged or losing expensive liquids.
  • Reducing Manual Checks: With the sensors doing the measuring, there's no need to open tanks or check levels by hand. This cuts down on work and keeps people safe from lifting heavy things.
  • Reliable in Tough Places: The sensors keep working even in hot, pressurized spaces where it's hard to check levels. They're good for keeping watch in places other sensors can't handle.
  • Precise Measurements: These sensors send back radar waves that can measure levels very accurately. They give exact numbers for better control of liquid levels.

How To Choose NBR Float Sensor

The following considerations will help one select the right NBR float sensor:

  • Industry needs

    Every industry has its specific requirements when it comes to choosing a sensor. For instance, food and pharmaceutical industries prefer non-contact NBR float sensors due to Ultrasonic float level sensor's ability to provide accurate readings without contamination risks. On the other hand, the manufacturing sector, where the requirement is for more robust sensors to measure liquids like oil or chemicals, should go for radar or magnetostrictive sensors.

  • Tank conditions

    While selecting the sensor, one should consider tank size, shape, and construction material. If the tank is small or has a complex shape, then capacitive or ultrasonics sensors would be a better choice as they are suitable for small or non-standard tanks. On the other hand, if the application is in a large tank, then a radar or magnetostrictive sensor would be suitable because of their effectiveness in large tank systems.

  • Environmental considerations

    It's important to consider the working environment of the sensor. For example, if the sensor is required to function in extreme temperatures or high pressure, then a radar or magnetostrictive sensor is the right choice because they are designed to function in these harsh environments. Similarly, for outdoor applications, one should choose a radar sensor because it can accommodate changing weather conditions.

  • Measurement accuracy

    Depending on the requirements for the level measurement, one should consider the accuracy and resolution of the sensor. If one needs high accuracy in liquid measurement, one should go for ultrasonics or radar sensors because of their ability to provide accurate readings. Lastly, when it comes to budget, capacitive or float switches are usually more affordable compared to radar or ultrasonics, which tend to be more expensive due to their advanced technology.

What NBR Float Sensor Can Be Compared With

NBR float sensors are suitable for various applications where accurate level measurement is essential. Some of their main competitors include:

  • Ultrasonic Level Sensors

    Ultrasonic float sensors measure liquid levels by sending sound waves to the surface of the liquid and calculating the distance based on the time it takes for the waves to bounce back. They are non-invasive sensors that work well with most liquids that have a smooth surface. Just like NBR sensors, ultrasonic sensors are used widely in water treatment, chemical storage, and food and beverage industries because of their accuracy and dependability.

  • Capacitive Level Sensors

    Capacitive level sensors measure the change in capacitance between two electrodes caused by the level of the surrounding material. Such sensors are very useful for detecting liquid levels in non-metallic and conductive tanks. Capacitive sensors are used constantly in the oil and gas, and chemical industries to measure levels of liquids and slurries. One of the reasons they are selected is their resistance to the harshest environmental conditions, which is similar to NBR sensors.

  • Radar Level Sensors

    Radar sensors, just like the Ultrasonic NBR float sensors, use non-contact methods to measure liquid levels by returning electromagnetic waves. These sensors work well in high-pressure and high-temperature environments. Radar sensors prove very useful in industries like petrochemical, mining, and power generation, where the liquids being measured have vapor, foam, or changing surfaces.

  • Thermal Dispersion Level Sensors

    Thermal dispersion float level sensors measure liquid levels by gauging the difference between temperatures in the surrounding liquid and that in the atmosphere. When such liquids cover the sensor, it loses heat to the liquid which is then transferred to the surroundings. This sensor works perfectly in both conductive and non-conductive liquids. However, it is best suited for industries where one deals with viscous fluids or slurries that easily carry heat away from the sensor.

Benefits Of NBR Float Sensor

  • Strong and Durable

    NBR is used in constructing these float sensors because it is a rubber-like material that is tough, flexible, and heat-resistant. The toughness and flexibility make the sensors unbreakable, even under pressure. The sensors are also able to function in extreme temperatures, whether too hot or too cold. This makes them suitable for a variety of operating conditions. The durability also ensures they are able to withstand harsh environments, making it less likely to have any damage or need replacements.

  • Chemical Resistance

    NBR is excellent at resisting many chemicals, oils, and fluids. This makes NBR float sensors very suitable for measuring liquids in the chemical, oil, and gas industries, where exposure to corrosive substances can degrade other materials. This allows them to maintain functionality and accuracy in the most crucial environments.

  • Cost Effectiveness

    Since NBR can be used to create float sensors on a large scale, its availability and ease of processing make these sensors fairly cheap compared to other types of level measuring float sensors. These sensors are proven to give good value when considering their strong performance and long life. NBR sensors are affordable upfront, eliminating the need to spend huge amounts of budget and saving on future costs for maintenance and replacements.

  • Easy Installation

    NBR float sensors are flexible and lightweight, making their installation easy, especially in difficult spaces. The ease of installation will eliminate the need for special tools or additional hardware. This allows the sensors to be integrated into existing systems seamlessly.

  • High Accuracy

    NBR float sensors offer a high degree of accuracy in liquid level measurements. Their precise mechanical design and buoyancy equilibrium enable them to provide consistent and reliable readings. This helps prevent overflows or shortages, improving safety.
