Product Introduction---  FST500-202  digital Pressure Switch

The FST500-202 Electronic Pressure Switch Can provide a continuous pressure monitoring and set the pressure switching point without supercharging. User can easily set the switching point and back-to-switching point without supercharging equipment.  And can define the switch type(normal open/close), damping time,the relay and NPN / PNP switch. The overload is from several uA to 500mA. The product can transfer the collected pressure signal into standard current and pressure signal output. The display and connection can rotate freely within 330 degrees so that it can be easily installed.
