MKS 937B Half-Rack Combination Controller, Operates up to Six Vacuum Pressure Sensors Simultaneously, NO Cards, RS232 and RS485 (built in). MKS Part Number: 937B-US-NANANA-NA. The MKS 937B Digital Combination Vacuum Gauge Controller operates up to six vacuum pressure sensors simultaneously. This highly flexible vacuum gauge controller supports a wide range of sensor technologies, including cold cathode, hot cathode, standard Pirani, convection Pirani, Baratron® capacitance manometers and absolute Piezo sensors for a measurement range from ultra-high vacuum to above atmospheric pressure. The 937B controller is designed for versatility, reliability and economy. The large, easy to read, liquid crystal display provides readout for up to six sensors simultaneously. The back lit LCD display, intuitive menus and simple push button front panel, allows for ease in setup of the 937B. This controller enables the use of any sensor card in each of the sensor card slots. The 937B can be configured with up to three hot or cold cathode type gauges, or three dual sensor cards for a maximum of six gauge connections. Set Points: Twelve independently adjustable set points are standard. This allows for the automation of process related functions. The set point values are nonvolatile and remain unchanged after power down or power failure. They are easily viewed and configured in the channel set up screen. The 937B also includes an adjustable control set point that turns the cold cathode or hot cathode gauges power off or on, at the desired pressures, extending the sensor’s life. Leak Test: The leak test mode includes a bar graph and variable audible alert to assist in locating leaks within a system. The function operates with the cold cathode, hot cathode, Pirani, and convection sensors. By taking advantage of differences in tracer gas sensitivity, this provides an excellent tool for helping locate coarse system leaks. Analog Output Signals: The controller provides analog output signals accessible on the rear panel connector. Three types of analog signals are available. Unprocessed analog signals are used to provide the fastest response times. The logarithmic output voltages are scaled so that 0.6 Volts equals one decade of pressure. Combination output can be created by combining up to three sensors with a combined range from 10-11 to 20,000 Torr. Digital Signals: In addition to analog outputs, the 937B communicates digitally for direct computer communication with built in connections for RS232 or RS485. A communication slot in the 937B chassis accepts an optional Profibus DPV1 board. The 937B can communicate with a host computer using either of these ports. Remote control of set points and cold cathode high voltage disable are some of the many features available with communications options. Signal cables and optional cards for the MKS 937B are available on this website.

MKS 626D 0.1 Torr Baratron Absolute Capacitance Manometer, Vacuum Pressure Gauge Sensor, Vacuum Fitting KF-16, PN 626D.1TDEThe 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 (<20 msec in many cases), low hysteresis, excellent repeatability, very high resolution (to 0.001% of Full Scale), exceptionally high corrosion resistance, and double-walled welded construction for operator safety. The sensor itself can withstand repeated exposures to 45 psia (3.1 bar) without permanent degradation or shifting, allowing it to operate in virtually any process system. The MKS 626D Baratron capacitance manometers operate at ambient conditions.

MKS HPS® Series 317 Convection Enhanced Pirani Sensor KF16 NW16 (PN 103170010SH) (Compatible with MKS 947 Convection Enhanced Pirani Gauge Controller) 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. Like all thermal conductivity sensors, the 317 sensor is innately gas-type sensitive. This feature makes it a simple solution for locating medium to fine leaks in vacuum systems. It complements a mass spectrometer leak detector, which is more efficient in finding smaller leaks. The sensor, which is shielded against RF noise, meets CE mark requirements and can be baked to 100°C. This 317 Sensor include standard vacuum connections such as this KF16 NW16 flange. The cable for this sensor is not included but available in standard 10 feet lengths.

MKS HPS® 423 I-Mag® Sensor Cold Cathode Vacuum Gauge KF25, NW25, compatible with MKS 943 Cold Cathode vacuum controller. MKS Part Number: 104230004 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. This is a Cold Cathode Sensor ONLY, the MKS signal cable and MKS 943 Controller for this unit are sold separetely on this website.

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.

MKS Hot Cathode Vacuum Sensor Nude Tube, Iridium Filament for 1x10-2 to 1x10-11 Torr, CF-2.75 in Flange Fitting. MKS Part Number: 100006842. The MKS Nude Tube Vacuum Sensor features a Yttria-coated Iridium filament for a 1x10-2 to 1x10-11 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.
