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. |

The single axis Inclination OEM Sensors NS-5/E and NS-15/E are newly developed sensors manufactured in micro system technology including modern technologies. Basically, it consists of measuring cell, manufactured in modern thin film technology, and integrated signal pre-processing, which has been realised in thick film technology, many connecting leads having been led out of the sensor in order to support the different applications. Thus for example precision can be increased as well as sensitivity and zero can be varied by using simple passive components. The sensor element itself and the hybrid electronics are located in a sealed-in ceramic package, the bearing surface of which has been ground precisely even. Consequently, due to the very low linear expansion coefficient of the ceramic parts of the sensor, a very precise and temperature-independent transfer of the measuring set onto the surface to be measured is possible. The dual axis Inclination OEM Sensors NS-10/E2 and NS-25/E2 are low-cost sensors especially designed for OEM sensor applications and are manufactured in micro systems engineering including modern technologies. Basically, it consists in the measuring cell, manufactured in thin-film technique, and is put on an SMD circuit board containing the accompanying electronic system. In the design of the circuit care has been taken that the sensors are of high flexibility with regard to the systems to be adapted. |
The Massa Ultrasonic Ranging Module is a precision electronic measurement device which includes an interface electronics module and one or two ultrasonic transducers, depending on the model selected. The Ultrasonic Ranging Module provides the OEM sensors market with a PWMLATCH output pulse, whose duration is proportional to the time required for the sound to travel between the transmit and receive transducers. The LATCH pulse width may be processed through additional circuitry for applications requiring position, level, profile, or thickness measurements. |
