The CA/04/D, /DH forms the interface section of a common mode interference (cmi) proof, piezo-electric transducer based, balanced measurement channel. The transducer output must be fully floating and transmitted via screened two core cable to the balanced input charge amplifier. Cmi induced via the transducer case or cable screen may manifest as a probably differing ground reference charge applied to each amplifier input, plus a component applied between inputs, and dependant upon the environment and the type and length of the transmission medium
