Hydrostatic level probe SGE-25.Smart

for liquidsHART4-20 mA

The SGE-25.Smart level probe is applicable to measure liquid levels in tanks, deep wells or piezometers. Principles of operation, construction The probe measures liquid levels, basing on a simple relationship between the height of the liquid column and the resulting hydrostatic pressure. The pressure measurement is carried out on the level of the separating diaphragm of the immersed probe and is related to atmospheric pressure through a capillary in the cable. The active sensing element is a piezoresistant silicon sensor separated from the medium by an isolating diaphragm. The electronic amplifier, which works in combination with the sensor, is additionally equipped with an overvoltage protection circuit, which protects the probe from damage caused by induced interference from atmospheric discharges or from associated heavy current engineering appliances. Configuration The following metrological parameters can be configured: ¨ the units of pressure; ¨ start and end-points of set range; ¨ damping time constant;
