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.
This telemetric torsion sensor measures the torque on rotating shafts. A new development is that the full bridge strain gauge, measurement amplifier and induced supply voltage are combined in a flexible substrate.
Installation could not be simpler with no soldering required as the sensor is glued to the shaft body, therefore no electronic or soldering skills are required for installation.
As a result the cost for torque monitoring of drives is lower and makes it an attractive choice for mass production in particular. It delivers the technical advantages of strain gauge technology for low-cost and production applications.
