Active thermocouple gauges The Edwards Active Thermocouple (ATC-E) gauges mount directly on the thermocouple tube to form a compact, stand-alone vacuum transducer. The ATC-E electronics module drives both medium and low pressure gauge tubes. These gauges offer a cost effective measuring solution for higher pressures. Edwards Active Strain Gauges operate from standard 20 to 36 V dc power supplies with a 0 to 10 V dc signal output making them easy to interface with the users equipment. Alternatively they are directly compatible with Edwards Active Digital Controllers or TIC Instrument Controllers.
