The MKS 626D unheated absolute Baratron® capacitance manometers are the latest analog, capacitance-based, high-performance vacuum and pressure transducers. They require ±15 VDC input voltage and provide a high-level 0-10 VDC analog output signal that is linear with pressure. This analog output can be interfaced with an MKS PDR2000 pressure controller, an MKS power supply/display instrument, or any instrument that meets these requirements. Changes in pressure/vacuum are determined by measuring the change in capacitance between the sensor’s diaphragm and an adjacent electrode disk. This capacitance change is converted to a useable output by patented signalconditioning electronic circuits. The radially-tensioned Inconel® diaphragm in the sensor provides very fast response (

The MKS HPS® 317 Convection-Enhanced Pirani Sensor provides dependable and stable pressure measurement at a very low cost. Since the only materials exposed to vacuum are stainless steel, nickel, glass, and platinum, the sensor is compatible with a wide array of process gases and is especially suitable for UHV applications. The platinum filament effectively eliminates any reading variance throughout a convection sensor’s higher measuring range. More accurate than a thermocouple sensor, the 317 Sensor measures over a wider pressure range and responds more rapidly to process pressure changes. The upper measuring limit of a convection-enhanced Pirani sensor is increased over that of a traditional Pirani sensor from 100 Torr to 1,000 Torr. This higher limit is useful when monitoring the pumpdown of a vacuum system from atmosphere to a base pressure. The sensor compensates for any changes in room temperature ranging from 10° to 50°C.

The 275 MKS Granville Phillips convectron pressure measurement gauge tube sensor is the industry standard convection-enhanced Pirani gauge. The MKS Granville Phillips 275 measures vacuum pressure from atmosphere to 1x10 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 MKS 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 the thermal conductivity property of the gas medium.

The 275 MKS Granville Phillips convectron pressure measurement gauge tube sensor is the industry standard convection-enhanced Pirani gauge. The MKS Granville Phillips 275 measures vacuum pressure from atmosphere to 1x10 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 MKS 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 the thermal conductivity property of the gas medium. (MKS Granville Phillips 375 Convectron Controller shown in photographs is avaliable but not included at list price).

The MKS Vacuum Sensor Card Cold Cathode is used with the 937B and 946 vacuum system controllers. These cards are used on controllers designed to control and display any flow transducer. The flow rate set point can be adjusted either through front panel controls or remotely through the rear panel analog interface. The 946 and 937B Vacuum System Controllers simultaneous readout & control of up to 6 sensors and gauges.

Using an inverted magnetron design, the 423 I-Mag® sensor can operate at pressures much lower than a traditional Penning cold cathode sensor, as low as 10-11 Torr with the proper controller. This increased pressure range makes the HPS® Cold Cathode sensor ideal for UHV use. A unique design feature of the HPS® Cold Cathode sensor is a second feedthrough for ion collection. In an ordinary single feedthrough design, any current leakage between the anode and ground would result in pressure measurement errors. Only the ion current from the cathode contributes to a measurement reading in a dual feedthrough design, making it ideal for process monitoring. With no filament to burn out, the 423 I-Mag® sensor is not ruined by sudden inrushes of air and is resistant to vibration damage. Additionally, there is no need to adjust the emission current or to degas the gauge, reducing response time to pressure changes. If bakeout is required, the magnets and sensor connectors can be removed and the sensor can be baked to 400°C.

to 1x10 Torr, CF-2.75 in Flange Fitting. The MKS Nude Tube Vacuum Sensor features a Yttria-coated Iridium filament for a 1x10 to 1x10 Torr vacuum measurement range and a 2.75 in. CF flange fitting. This Bayard-Alpert style ionization vacuum sensor, which uses a fine wire collector located in the center of a grid. Because of its small area, few x-rays hit the collector, and a vacuum gauge can measure pressures to very low levels. Because the sensing portion of the tube is located within the vacuum system and experiences the system true pressure, nude tubes give a representative pressure measurement and respond more quickly than a glass envelope sensor to pressure changes. Signal cables for this cold cathode vacuum sensor are available on this website.
