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 (<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. They are available in full scale pressure/vacuum ranges from 0.1 to 1000 Torr and are suited for many industrial, electronic, and research applications.

These listing is for an MKS Type 626D capacitance manometers having a 15-pin D-subminiature signal connector, a 0.1 Torr full scale maximum vacuum pressure reading value, a KF-16 vacuum flange connection, and have MKS part number 626D.1TDE.
