Model 709 Electronic Differential Pressure Switch with Transmitter is an ideal instrument for low pressure measurements in any industrial pneumatic applications.
The process pressure is directly measured by a monolithic silicon pressure sensor, the output of which is proportional to the applied pressure and fed to the microcontroller circuitry.
The measured process values are displayed through a 4 digit RED LED Display. In addition 2 On / Off Relay output and 4 20 mA analog current output are provided.
The setpoint values are easily set by using 3 push button keys. The entire circuitry is housed in a IP:65 compliant weatherproof enclosure suitable for surface / wall (or) pipe mounting.
Zero shift of 15 mm can be adjusted through internal push buttons.
