These 2-inch and 2-1/2 inch pressure gauges feature built-in electrical switches for activating alarms and/or shutting down equipment.
The 20P Series (2 in./51 mm dial) and the 25P Series (2-1/2 in./64 mm dial) Swichgage models are diaphragm-actuated, pressure-indicating gauges with built-in electrical switches. These switches are used for tripping alarms and/or shutdown devices.
Ranges are available from 0-15 psi (103 kPa) [1.0 bar] through 0-100 psi (690 kPa) [7.0 bar].
The gauge 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 are assured by a unique, unitized diaphragm chamber. A built-in pulsation dampener helps eliminate pointer flutter and is removable for cleaning. For models 20P and 25P, the gauge 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.
Model 20PE has internal snap-acting SPDT switches.
Gauge-only models, without switches, are also available.
Base Models
20P and 25P Series Swichgage
The gauge pointer makes with an adjustable contact to complete a pilot-duty circuit.
20PE Swichgage (was 20EO)
Features internal snap-acting SPDT switches, instead of the single pole/pointer contacts. When the switch closes on falling pressure, it becomes set, as pressure rises the switch resets.
20P7 Lockout Swichgage
Same as 20P Series. It also includes a front, semi-automatic 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.
