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)
