ATC-E Electronics module

The Edwards Active Thermocouple (ATC-E) gauges mount directly on either the ATC-D or ATC-M thermocouple tubes to form a compact, stand-alone 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.

Features and Benefits

• 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 +10 V 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 meters
• Choice of medium and low pressure gauge tubes. The ATC-D covers from 50 to 5 x 10^-2 Torr while the ATC-M covers from 1 to 10^-3 Torr

Applications

• Active thermocouple gauges are ideally suited to applications where a simple rugged gauge is required to measure higher pressures.
