High quality gas differential pressure transmitter
KL-PS300 gas pressure differential transmitter has high sensitivity, high precision and strong anti-overload capability. Manufactured with imported sensors, the sensor and amplifier circuit are highly integrated; ABS flame retardant housing, strong anti-interference ability, acid and alkali resistance, long-term stability and reliability.
KL-PS300 gas pressure differential transmitter adopts imported pressure chip. Sensitive components use diffusion or ion implantation to form resistance and connect to Wheatstone bridge. Micro-machining technology is used to form pressure sensitive diaphragm under the bridge. When pressure is applied to the diaphragm, the resistance value changes and a linearized output signal is generated that is proportional to the applied pressure. When we add DC power to the Wheatstone bridge, a DC voltage signal will be output. After the second conversion line, the two-wire system 4 ~ 20MA output is realized. (Optional 0 ~ 10V output, 485 protocol output).
1 with LCD display, zero full scale adjustable on site.
2 Good stability, long-term stability at full scale and zero can reach 1% FS / year. Within the compensation temperature range of 0 to 70 ° C, the temperature drift is lower than 1% FS, and it is lower than 1% FS in the entire allowable operating temperature range.
3 It has reverse protection and current limiting protection circuit. When the positive and negative poles are reversed during installation, the transmitter will not be damaged. When abnormal, the transmitter will automatically limit the current to 35mA.
4 Solid-state structure, no moving parts, high reliability and long service life.
5 High precision measurement from wind pressure to steam is not affected by the quality of the measured medium.
6Easy installation, simple structure, economical and durable
