Active Thermocouple Gauge

Edwards 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.

Drive electronics mount directly on the gauge tube

which simplifies the system design and saves valuable rack space

Wide range regulated internal power supply

runs from standard d.c. power supplies from +13.5 to +36 V and is tolerant to voltage fluctuations

Standard analogue outputs of 0 to +10V d.c

and gauge identifier allows for easy interface with a computer or PLC and provides fault output indication.

Adjustable set-point with vacuum status LED

can be used for process control and interlocking and includes a digital vacuum status signal with set-point level ready visually.

Low output impedance and integral Faraday shield

provides a high level of noise immunity and permits long cable runs of up to 100 metres
