Industrial Temperature Gauges

Mechanical Temperature Gauges 20T / 25T

20T/25T Mechanical Temperature Industrial Gauges

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.

  • Combination Indicating gauge and Limit Switch
  • Critical/High Temperature Limit Switch Is Visible and Adjustable (Most Models)
  • Switch Can Activate Alarms and/or Shut Down Equipment
  • Contact Grounds Through Case

The 25DP series mechanism is enclosed in a steel case coated to resist corrosion. The A25DP series has a polycarbonate case sealed from the environment. Both feature a polycarbonate, break-resistant lens to help protect the instruments.

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 have self-cleaning motion to ensure electrical continuity.

Additional features:

  • Constant visual indication of the condition of your filter is shown on the dial.
  • Two instruments in one with an accurate indicating gauge and adjustable p.s.i.d. limit switch reduces inventory and installation time.

These rugged, instruments are face sealed from the environment by the unique combination of a polycarbonate case and lens, a polished stainless steel bezel and O-ring seals. Tese gauges are sealed from the external environment.  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.

For series A25P, 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 have self-cleaning motion to ensure electrical continuity.

Model A20PE has internal snap-acting SPDT switches for three wire control and can be wired to make or to break a circuit.

gauge-only models, without switches (Murphygauge instrument) are also available.

Mechanical Pressure Gauges 45APE Series

Mechanical Pressure Gauges 45APE Series
  • Combination Indicating Gauge with Independent Low and High Snap-Acting Switches
  • Field-Adjustable and Highly Visible Low and High Pressure Trip Point Indicators
  • Dual-Sector Geared Movement Allows for Full-Scale Indication and Set Point Control
  • Panel and Surface Mount Versions Available
  • Latching Control Relay Versions Available

The 45APE Series gauge instrument is a mechanical gauge for pressure indication. It includes two adjustable SPDT switches. These snap-acting switches can be used for start and stop, to trip alarms and to shut down equipment. Ranges are available from 30 psi (207 kPa) [2.06 bar] thru 5,000 psi (34.48 MPa) [344.73 bar].

The 45APE Series utilizes a bourdon tube sensing unit with a stainless steel dual-sector geared movement. Each of the sectors drives separate pointers when pressure is applied to the bourdon tube. The indicating pointer (visible pointer) shows actual pressure reading, including below and beyond the low and high trip points. The low and high trip points are adjustable independently on the gauge front lens. The switch operator pointer (behind the dial) is calibrated to follow the indicating pointer. The low and high trip point indicators arrest the switch operator pointer. As pressure decreases or increases through the principal of lost motion, the respective snapswitch is tripped.

The 45APE Series models are widely used in applications requiring pressure indication and Form C low and high pressure switches.
