The NIVAPRESS SGE-25 hydrostatic level probe can be used to measure the level of clear liquids and wastewater stored in tanks, deep wells, or piezometers.
This sensor is especially recommended for monitoring and controlling submersible pumps and wastewater lifting stations.

The NIVAPRESS SGE-25 sensor is immersed in the liquid. The pressure on the sensor increases proportionally with the depth of immersion.

The pressure is measured at the immersion depth of diaphragm, connected to atmosphere through a capillary inside the cable. The active sensing element is a piezoresistive type isolated by a very strong hastelloy diaphragm. An electronic amplifier operating in connection with the sensor, converts the measurement into a 4-20 mA or 0-10 V analog signal.

The anti-surge circuit protects the instrument from damages caused by atmospheric disturbances or high power devices.

Mounting accessories:
Installation of the NIVAPRESS SGE-25 probe is simplified by the use of an attachment system, such as the NIVAPRESS SGE-25.

Once lowered to the reference level, the probe can either hang freely from the cable or rest at the bottom of the tank.

Installation precautions:
The junction box BJSC with pressure compensation, allows to fix the sensor and ensures the balancing of atmospheric pressure through an integrated vent on the front of the housing. It significantly reduces the risk of dust and moisture entering the device. It is also recommended to extend the life of the probe cable.

The cable can be extended using a standard signal cable. For connecting longer cables, we recommend using the additional wall-mounted surge protection box, BPS 102.
