EK Engineering Fischer - Model NB10 -Liquid Level Transmitter / Well Probe with Hydrostatic Monitoring

Fischer NB10 well probe is based on highly sensitive pressure sensor with silicon membrane measuring element.

A DMS resistance bridge is attached to the rear of this silicon membrane using thin-film method. The well probe NB10 is equipped with an indirect hydraulic pressure sensor which guarantee system-inherent dead space latitude. An elastic membrane isolate the pressure sensor from the medium to be measured.

Transfer fluid is filled between membrane and pressure sensor. Thus, when pressure is applied, transfer fluid transfer pressure to deforms silicon membrane.. As a result, resistance of the resistance bridge changes linear proportional to the measuring pressure. Thus, electronic module converts changes in resistance to standard electrical signals.
