Active Thermocouple Gauge
Edwards Active Thermocouple Gauge (ATC-E) is suitable for measuring from 50 to 10⁻³ Torr, with integral set-point for OEM use and LED indication of vacuum status.
The ATC-E mounts directly onto either ATC-D or ATC-M thermocouple tubes to form a compact stand-alone transducer to simplify the system design and save valuable racking space. The ATC-E electronics module drives both medium and low pressure gauge tubes, providing a cost effective measuring solution for higher pressures.
Active thermocouple gauges are ideally suited where a simple rugged gauge is required to measure higher pressures.
