Capacitance Manometer
Available in Standard Torr, kPa and mbar Vacuum Ranges
etra's Model 720 is an accurate, low
)cost pressure manometer for vacuum applications. The 720 is designed to be used with pressure media compatible with Inconel®. The all-welded construction elim­inates stability issues inherent in other designs due to frictional contact between dissimilar metals.
Setra's patented variable capacitance sensor design combines the ultimate in simplicity, with high accuracy and superior thermal stability. It features an Inconel® diaphragm and an 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.
The Model 720 is offered with a variety of vacuum pressure fittings. Its rugged design, high overpressure capability (see table), and wide operating temperature make the Model 720 ideal for the most demanding applications.
When it comes to a product to rely on - choose the Model 720. When it comes to a company to trust - choose Setra.
