OEM sensors data acquisition systems digital panel meter OEM SENSORS Durham Instruments is proud to be the exclusive Canadian Distributor for Schaevitz Sensors. Schaevitz Sensors designs, manufactures, and markets low to medium volume, rugged industrial OEM sensors, with a wide choice of proven sensors for linear and rotary position, pressure, slope/tilt, dimensional gaging, associated instrumentation and customized systems. Biaxial inclination OEM sensors use 2 pieces of basic cells. The sensor works in the way that an electrolytical fluid is formed out by applying an AC-voltage on the planar electrode structures. By tilting the sensor, the fluid level over the different electrodes and in consequence the conductance of the stray field changes. Using a difference measurement principle, the tilt angle and the tilt direction can be measured. With a special electrode and circuit design the temperature coefficient is almost completely compensated.
