Hydrostatic level sensors NIVAPRESS PCE-28P / APC
The hydrostatic level sensors NIVAPRESS PCE-28P and APC are applicable to the measurement of the level of clear liquids in open reservoirs, canals, streams, etc ...
The probe measures the liquid level by comparing the height of the water column with the resulting hydrostatic pressure. The pressure measurement is carried out at the membrane, connected to the atmospheric pressure through the capillary located in the cable. The active sensing element is a piezoresistive type silicon sensor insulated by a membrane.
An electronic amplifier operating in conjunction with the sensor, converts the measurement into an analog 4-20 mA signal. This amplifier is equipped with an overvoltage protection circuit to protect the probe from damage caused by interference induced by atmospheric discharges or from the combination of high current devices.
- Measuring ranges from 0 to 200 to 0 to 3000 mm H2O
- Elements in contact with the fluid: Stainless steel 316 L
