Industrial Temperature Gauges |
 |
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

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.

45APE Series Mechanical Pressure Gauges |
 |
- 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.

PD8100 Series Pressure Sensors and Instruments |
 |
- Used on Controllers, Instruments and Recorders to Dampen Pressure Pulsation
- Eliminate Gauge Pointer Flutter
- Aids in Providing More Accurate Pressure Indication
- Decreases wear on a Gauge’s Geared Movement
The PD8100 Series eliminates pointer flutter on pressure indicating gauge devices which are subject to pulsating pressure from reciprocating pumps or compressors. It also allows a close setting of high and low contact points providing for more accurate pressure indication and control of equipment.
The PD8100 Series decreases wear on geared movements and increases the life of pressure indicating instruments by eliminating excessive gauge strain and unnecessary movement, a necessity which quickly pays for itself by protecting any pressure indicating and control instrument which is subject to pulsation.
PD8100 SERIES IS NOT FOR USE ON OXYGEN OR LIQUID OXYGEN APPLICATIONS.
The PD8100 is quality built with a large diameter valve stem wheel for ease of adjustment and features clearly printed operating instructions.
Machined from 1 3/8-inch (35 mm) hex bar stock, a two degree taper on the valve and stem assure positive dampening.
It’s available in brass, carbon steel, 303 stainless steel or 316 stainless steel to meet pressure and environmental requirements with either 1/2 NPT or 1/4 NPT inlet connections. |

PT167EX Mechanical Pressure Gauges |
 |
The FW Murphy PT167EX is a pressure gauge instrument connected to a threaded pressure diaphragm housing. The gauge is enclosed in an explosion-proof case and is CSA rated for Class I, Division 1, Groups C and D.
The PT167EX is a pressure-indicating gauge with adjustable low and high pressure limit switches. When the gauge pointer touches the low or high limit switches, an electrical circuit is completed which can operate alarms and/or shut down equipment.
The 2 NPT, sealed diaphragm housing is attached directly to the gauge connection. The diaphragm housing is filled with a silicone fluid so that pressure against the diaphragm causes the gauge to respond. The housing seals the sensing element from the medium being measured.
Applications include highly viscous liquids such as crude oil on lead line applications. Other applications have included asphalt, sludge, abrasive materials, etc. |
