Pfeiffer - Model PNE -Pneumatic Level Sensor
The pneumatic level sensor PNE converts air pressure generated by the hydrostatic backpressure of the water level into a proportional, standard electrical signal. It is possible to correct the zero point and scaling using a single button. False settings and system errors are indicated via LEDs. The air dome or the bubble tube can be utilised in potentially explosive atmospheres.
