New MURPHY Swichgauge model 10-35-0949 fluid temperature gauge with high limit switch. Can be used with coolant, oil, diesel fuel or hydraulic fluid. 1/16" Hex wrench adjustment knob on front to adjust switch set point

The 20 Series (2 inch/51 mm dial) and the 25 Series (2-1/2 inch/64 mm dial) Swichgauge models are diaphragm-actuated, temperature-indicating gauges with built-in electrical switches for tripping alarms and/or shut-down devices.
Ranges are available from 32°-120°F (0°-45°C) through 300°-440°F (160°-220°C).
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.

These vapor-actuated gauges feature a sealed capillary tube and a sensing bulb. When subjected to heat, the liquid in the sensing bulb changes to vapor creating pressure against the diaphragm mechanism. The diaphragm translates this vapor pressure into a mechanical gauge reading. For series 20T and 25T, the gauge 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 grounded through the Swichgauge case. They have a self-cleaning motion to enhance electrical continuity.

The non-contact infrared forehead thermometer is intended for use to measure adult and children body temperature without making physical contact. Simply point the thermometer at the person's forehead and from 3cm to 5cm away, click “Scan”. Body temperature will instantly be displayed on the coloured screen, and for convenient visual reference, the backlight will indicate Green for normal temperature, Orange for elevated temperature and Red for high temperature and fever The small and user friendly thermometer can measure in three modes, Body, Room and Surface temperature.

Service Intended

Suitable for media such as air, water, oil, gas, and chemicals that will not attack brass parts. Typical applications will be in demanding automotive, portable air compressors / generators and earth moving equipment where distance reading is required. Vibration resistant.

The SDB Series are direct-mounting temperature devices. They provide an accurate direct-reading gauge with an adjustable limit switch to activate alarms and/or shutdown. A knob on front of the instrument allows you to adjust the limit switch trip point. Pointer movement is actuated by a bi-metallic sensing element. Models SDB500, SDB501 and SDB500EX have a temperature range of 100° to 500°F (40° to 260°C). SDB500EX enclosure is explosion-proof and CSA listed for Class I, Group C and D hazardous locations. The SDB1000 has a temperature range of 200° to 1000°F (100° to 500°C). The most common use of the SDB Series is to monitor gas compressor temperatures. Engine exhaust temperature can also be monitored to indicate overloading or lean fuel mixtures, or use the SDB to help coordinate loads on twin-engine installations

• Easy to read dial
• Bi-metallic sensor
• Two ranges:
  - 100 to 500°F (40 to 260°C)
  - 200 to 1000°F (100 to 500°C)
