Aftermarket Murphy 100 PSI Pressure Switch Gauge 20P-100 05703115

Aftermarket Murphy 100 PSI Pressure Switch Gauge 20P-100 05703115Replace Part Number: 20P-100, 20P100, 05703115Description:The Murphy 0-100 PSI Mechanical Pressure Swichgage 20P-100 is a diaphragm-actuated, pressure-indicating gage with a built-in electrical switch. This swichgage is used for tripping alarms and/or shutdown 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 Swichgage case and have self-cleaning motion to ensure electrical continuity. The gage pointer makes with an adjustable contact to complete a pilot-duty circuit. 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 and air pressure.Features:2 inch/51 mm dialCombination Indicating Gage and Limit SwitchSwitch Can Activate Alarms and/or Shutdown EquipmentExceeds SAE StandardsSpecifications:Part No.: 20P-100Range: 0-100 psi (690 kPa) [7.0 bar]Dial: White on black, dual scale; U.S.A. standard scale is psi/kPaCase: Plated steel; mounting clamp included (except for direct mount models)Bezel: Polished stainless steelLens: Polycarbonate, high-impactOil: Silicon OilTemperature Range: Ambient: -40闁硅櫣鐓?(-40闁硅櫣鐓? thru 150闁硅櫣鐓?(66闁硅櫣鐓?; Process: -40闁硅櫣鐓?(-40闁硅櫣鐓? thru 250闁硅櫣鐓?(121闁硅櫣鐓?Process Connection: 1/8-27 NPTM brassSensing Element: Beryllium copper diaphragmAdjustable Limit Contact: SPST contact; pilot- duty only, 2 A @ 30 VAC/DC; Normally Close (NC) when the low limit is met.
