About the MCH Amplifiers

The MCH-P oscillator coupled with an LVDT or ½ bridge transducer provides a channel of measurement delivering a voltage output (±10 V nom.). With an external input voltage, it is possible to have a shift in order to obtain a 0 V to 10 V output.

Key features MCH

Hybrid technology: compact and reliable module
Oscillator and demodulator outputs protected against short circuits
Easy to use: few external components
Small size: SIL16 housing
Possibility of vertical or horizontal mounting by bending the pins to 90°
Synchro input for multi-channel applications
Synchronous demodulator
400 Hz filter: response time <2 ms
Low output noise: <5 mVrms

Applications MCH

The MCH-XX module is made of 3 sub-components:

3,5 & 5 KHz oscillator
Synchronous demodulator
Low pass filter (third order 400 Hz Butterworth type)

Gain and zero are adjustable. This module is a conditioner for all inductive sensor types (LVDT, RVDT, half Bridge)
