Power amplifying integrated circuit

electronicfor sensors

The Manner sensor signal amplifier captures the measuring signal from the rotating sensors. In addition to DMS sensors, other sensors such as thermocouple elements, PT 100, Hall, piezo and Micro-Epsilon sensors and potentiometers can be connected. The evaluation unit supplies a high frequency signal from which the energy for the sensor signal amplifier is generated. This in turn generates the power supply for the connected sensor. The bridge supply voltage generated is short-circuit proof and highly stabile. An integrated voltage monitor guarantees fault-free operation. In addition, the function of a DMS bridge and the entire measuring chain can be checked via the optional remote shunt calibration function. During commissioning and maintenance, it is thus possible to check the calibration of the entire system with an off-load measuring chain. The setting of the zero point and the measuring sensitivity of the sensor signal amplifier is either fixed using resistors soldered into place, or programmed from a computer using the RMC technology.
