This specification describes the MEGGITT Model 1772M1 Remote Charge Converters are designed for high-temperature PE (HTPE)transducers that can operate at temperatures up to + 815°C (+ 1500°F).
The circuit is connected to the PE with a high temperature coaxial cable. The circuit makes it possible to operate with high-temperature PE typically having resistance as low as 10 kΩ at high temperatures. The 1772M1 has a gain of 1 or 2. The sensitivity of the circuit is not affected by the PE transducer’s and cable capacitances.
