The 385620-4-GQ-T Convectron® ATM Vacuum Transducer with Display features DeviceNet communications and a 0.25 in VCR female fitting. The Convectron® ATM module combines control electronics with a piezo-resistive diaphragm sensor and the proven Convectron sensor to provide a continuous measurement from low vacuum to atmosphere. The compact design is easy to install and operate and includes a set point relay activation at a defined differential pressure from atmosphere. The Convectron ATM module eliminates the need for two sensors in those applications that require low pressure measurement and an accurate indication of differential pressure at atmosphere, such as vacuum system loadlocks. It is available with DeviceNet™ interface. The Convectron heat loss sensor provides vacuum pressure measurement over seven decades from 1x10^-4 Torr to atmosphere. The diaphragm sensor technology measures the differential pressure between the inside of the vacuum space and the outside environment and activates a set point relay when a defined differential pressure is achieved. All units provide set points that are used to indicate a low vacuum level and when the defined differential pressure has been reached. This DeviceNet version with display that features a bright, 3-digit indication of the instantaneous pressure measurement.
