50mm Non-linear Electrical Output Signal External Cable CNG Pressure Gauge 400 bar
Description
Resistive CNG pressure sensor using the AEB standard for 1/4 radial thread.
With mechanical reading by means of a gauge directly on the sensor (tank level indication from empty to full is shown in a clockwise direction).
The sensor transforms the pressure of a tank into an electrical signal if combined with a switch unit / AEB indicator pre-arranged for such purpose.
No calibration required.
Applications
Measurement of the filling pressure in gas tanks for CNG vehicles
Special features
Non-contact optical sensor (wear-free)
Nominal size 2”(50 mm)
Robust steel case
Scale range 0/6,000 PSI
