MKS Granville-Phillips 355 Micro-Ion ATM Modular Vacuum Pressure Transducer, Digital Display Torr Readout, DeviceNet, Yttria-Coated Iridium Filament, 2.75 in. CF Inlet Pressure Measurement from 1 × 10-9 Torr to Atmosphere The MKS Granville-Phillips 355 Micro-Ion ATM Module combines proven Micro-Ion ionization gauge technology with a miniature Conductron heat loss sensor to provide accurate, continuous pressure measurement from high vacuum to atmosphere. Using its diaphragm sensors, this product is capable of providing accurate absolute pressure up to atmosphere along with precision indication of vacuum chamber differential pressure from ambient. The unique sensor design eliminates thermal effects that can influence the performance of the heat loss sensor at higher pressures. This small module combines all four sensors and control electronics in a compact modular design, reducing the number of gauges required on a chamber while minimizing the required installation space. The full-range pressure measurement is provided through a DeviceNet digital interface. This DeviceNet version includes configurable setpoints for process control, allowing the relays to be assigned at any pressure across the vacuum pressure range or to a specific differential pressure value. Benefits Include: Continuous pressure measurement from 1 × 10-9 Torr high vacuum to atmosphere. Precision differential pressure measurement at atmosphere. Eliminates the need for discrete atmospheric switches. Eliminates the need for three separate sensors. Yttria-coated iridium ionization gauge filament increases equipment uptime. Automatic ionization gauge activation and deactivation. Configurable setpoint relays for process control. Field-replaceable gauge assembly. DeviceNet digital output. Modular vacuum gauges are an ideal solution for applications that do not require front-panel displays and controls. These compact, convenient, reliable, and cost-saving modules have the control electronics mounted directly on the gauge. The all-metal package provides a rugged enclosure and a high level of immunity to electrical noise. Mini-Convectron Modules use the latest electronics technology to operate the Granville-Phillips® Convectron® Gauge. The Convectron Gauge has become an industry standard. It is a unique variation of thermal conductivity gauges where pressure measurement is based on the rate of heat loss from a sensor wire. Unlike traditional thermocouple and Pirani gauges, which rely only on conductive heat loss, Convectron Gauges also take advantage of heat loss due to convection at higher pressures. This extends the range of accurate, repeatable pressure measurement all the way to atmosphere.
