MKS
Capacitance manometers are highly accurate and repeatable pressure sensors that are insensitive to gas composition. The sensing element in a capacitance manometer is a diaphragm that deflects with applied pressure, changing capacitance. MKS manufactures the diaphragm gauges almost exclusively using nickel-based alloys such as Inconel and Incoloy, making them highly resistant to corrosion when matched to the process.[1]
The 722C provides a signal output of 0 - 10 VDC or 0 - 5 VDC. The sensors are fully welded and 100% leak-checked prior to assembly. In the event of an extremely rare failure of the diaphragm, the process gases are completely contained within the sensor, preventing escape to the outside environment.[1]
