| | 820 Series - Absolute ► Standard Torr, kPa and mbar Vacuum Ranges ► Wide Compensated Operating Temperature ► Protected Against Miswiring The 820 Series sensor is an accurate, low-cost absolute sensor for even the most demanding vacuum applications. An all-welded construction eliminates stability issues inherent in other designs caused by frictional contact between dissimilar metals. 820 Series manometers are offered with a variety of vacuum pressure fittings, and a rugged design provides a high overpressure capability over a wide temperature range.

| | How They Operate 820 Series manometers feature an Inconel® diaphragm and insulated electrode, which forms a variable capacitor. As pressure (vacuum) increases or decreases, the capacitance changes. This capacitance is detected and converted to a fully-conditioned linear voltage output signal. | |
