MKS Granville Phillips 275 Mini Convectron Module Gauge, 3-Digit display, 1/8 inch NPT, 275904-EU-T

The MKS Granville Phillips 275 mini convectron module gauge comes with a 3-Digit display on the sensor and 2 built-in adjustable two set points pressure reading and a vacuum connection of 1/8 NPT pipe thread, 1/2 inch tubulation. This gauge measures vacuum pressure from atmosphere to 1x10-4 Torr and are ideal for roughing and foreline pressure measurement. It provides reliable fast response measurement, in milliseconds rather than seconds as in the case with thermocouple-type gauges. The high accuracy of the Granville Phillips 275 mini convectron module vacuum gauge sensor and repeatability help insure that processes start at the desired pressure time-after-time. However, they are sensitive to the chemical composition of the gases being measured and are termed a relative pressure measurement method, that is, they determine the pressure indirectly from the thermal conductivity property of the gas medium. (Granville Phillips Convectron Controller shown in photographs is available but not included at list price).

Modular vacuum gauges are an ideal solution for applications that do not need front panel displays and controls. These compact, convenient, reliable, 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 that use only conductive heat loss, Convectron Gauges take advantage of heat loss due to convection at higher pressures. This extends the range of accurate, repeatable measurement to atmosphere.
