20P7-K-200 Pressure Swichgage (05703579)
20P7-K-200: 2" Pressure Swichgage; Semi-automatic lockout; "FS" Contact; 0-100 psi (05703579)
The 20 Series (2 inch/51 mm dial) Swichgage models are diaphragm-actuated, pressure-indicating gages with built-in electrical switches.
These switches exceed SAE standards and are used for tripping alarms and/or shut-down devices.
The gage mechanism is enclosed in a steel case coated to resist corrosion. A polycarbonate, break resistant lens and a polished, stainless steel bezel help protect this rugged, built-to-last instrument.
Accuracy and protection from moderate overpressure is assured by a unique, unitized diaphragm chamber. A built-in pulsation dampener helps eliminate pointer flutter and is removable for cleaning.
The gage pointer acts as a pressure indicator and as one switch pole which completes a circuit when it touches the adjustable limit contact. Contacts are grounded through the case and have self-cleaning motion to ensure electrical continuity.
The Swichgage® was specifically designed to protect engines/equipment in oil field, marine, irrigation, construction and trucking applications to monitor engine lube pressure, water pump pressure, hydraulic pressure, air pressure, etc.
Features:
The gage pointer makes with an adjustable contact to complete a pilot-duty circuit.
Include a front, semiautomatic lockout for startup override. This built-in device holds the pointer away from the contact on startup. When pressure exceeds the set point, the lockout is automatically disengaged.
