Overview

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.

Technology

Thermocouple gauges are similar to Pirani gauges except that the temperature of the filament is measured by a thermocouple. The filament is heated and the cooling effect of the gas present gives an indication of the pressure. The junction of a thermocouple is held very close to the filament by a small glass bead and as the temperature of the filament changes a voltage is induced across the thermocouple. The electronics module consists of a power supply for the filament and measuring circuit for the thermocouple output.
 
Thermocouple gauges are gas dependent.

Applications

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