Bamo Hydrostatic Level Transmitter NIVAPRESS SGE-25

The NIVAPRESS SGE25 probe 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.

Precautions for installation:

The installation of the NIVAPRESS SGE-25 is simplified by the use of a fastening system, such as a suspension clip (a) or/and a BJSC holder (b). The probe can hang freely at the end of the cable or lie down at the bottom of the tank.

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 entry of dust and moisture. It is also recommended to extend the life of the probe cable. A cable extension could be done with a standard cable. For large cable distances it is necessary to use the box junction BPS102 (wall mount) with surge protection device.
