供应Granville-Phillips 275316

granville phillips 275 convectron gauge, part number 275316 for nw40kf model: 275316sensor material - gold plated tungsten other materials exposed to gas - 304 stainless steel, borosilicate glass, kovar, alumina, nife alloy, polyimide internal volume - 40cm3 operating temperature - 0°c to 50°c ambient , non-condensing bakeout temperature - 150°c maximum, non-operating, cable disconnected connection - nw40kf range - from atmosphere to 10-4torr (10-2pascal) the 275 granville phillips convectron pressure measurement gauge tube sensor is the industry standard convection-enhanced pirani gauge. the granville phillips 275 measures vacuum pressure fromatmosphere 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 withthermocouple-type gauges. the high accuracy of the granville phillips 275 convectron vacuum gauge sensor and repeatablilty 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 thethermal conductivity property of the gas medium.
