Murphy 130-250F Temperature Swichgage 2 in. with 30 Ft Capillary and Snap-Acting Switch - Oil Sealed - A20TE-OS-250-30-1/2
The Murphy 130-250F Temperature Swichgage 2 inch Oil Sealed with 30 Ft Capillary and Snap-Acting Switch A20TE-OS-250-30-1/2 is a diaphragm-actuated, temperature-indicating gage with built-in electrical switch for tripping alarms and/or shutdown devices. This rugged, built-to-last instrument is fully sealed from the environment by the unique combination of a polycarbonate case and lens, a polished stainless steel bezel, and O-ring seals. This vapor/pressure actuated gauge features a sealed capillary tube and a sensing bulb. When subjected to heat, the liquid in the sensing bulb changes to vapor creating pressure against a diaphragm mechanism. The diaphragm translates this vapor pressure into a mechanical gage reading.The gage pointer acts as a temperature indicator and as one switch pole which completes a circuit when it touches the adjustable limit contact. Contact(s) are isolated from ground. They have self-cleaning motion to enhance electrical continuity. Models with internal SPDT snap-switches, instead of the single pole/pointer contact(s). When the switch closes on rising temperature, it becomes Set. As temperature decreases the switch Resets. Applications for A20 series temperature swichgage instruments include: engines and equipment in oil field, marine, irrigation, construction and trucking industries. Monitoring engine coolant temperature, crankcase oil and transmission oil.FEATURES:2 inch/51 mm dialO-ring SealsPolished Stainless Steel BezelCorrosion Resistant Polycarbonate CaseIndicating Gage and Limit SwitchSwitch Can Activate Alarms and/or Shut Down EquipmentContact(s) Isolated From GroundOS = Oil sealed (Silicone Oil)Internal Snap-Acting SPDT Switch PRODUCT SPECIFICATIONS:Part No.: A20TE-OS-250-30-1/2Range: 130-250°F (60-121°C)Adapter Nut: 1/2-14 NPTDial: White on blackCase: Glass filled/Polycarbonate, corrosion-resistant; steel mounting clamp includedBezel: Polished stainless steelPointer: Tempered nickel silver; red tipLens: Polycarbonate, high-impactSensing Element: Beryllium copper diaphragmSensing Bulb: CopperCapillary: PVC armored copper; 30 ft.Sensing Bulb: CopperGage Accuracy: 130 to 250°F (54 to 121°C) Temperature Range; ± 9°F (± 5°C) Lower 1/3 of Scale; ± 5°F (± 2.4°C) Middle 1/3 of Scale; ± 4°F (± 2°C) Upper 1/3 of ScaleMaximum Temperature: 310°F (154°C)Snap-Switch Rating: SPDT, 3 A@ 30 VDC inductive; 4 A @ 125 VAC inductiveWiring: Number 4 screw terminalsUnit Weight: 11.9 oz.
