Murphy Mechanical Pressure Gauges

Mechanical Pressure Gauges 20P - 25P Series

Mechanical Pressure Gauges (20P/25P Series)

Mechanical Pressure Gauge (20P/25P Series)

The 20P Series (2 inch/51 mm dial) and the 25P Series (2-1/2 inch/64 mm dial) Swichgage models are diaphragm-actuated, pressure-indicating gages with built-in electrical switches. These switches are used for tripping alarms and/or shutdown devices.

Ranges are available from 0-15 psi (103 kPa) [1.0 bar] through 0-100 psi (690 kPa) [7.0 bar].

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. For models 20P and 25P, 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 case and have self-cleaning motion to ensure electrical continuity.

Model 20PE has internal snap-acting SPDT switches. Gage-only models, without the switches (Murphygage®) are also available.

Base Models

20P and 25P Series Swichgage

The gage pointer makes with an adjustable contact to complete a pilot-duty circuit.

20PE Swichgage

20PE (was 20EO)
Features internal snap-acting SPDT switches, instead of the single pole/pointer contacts. When the switch closes on falling pressure, it becomes set, as pressure rises the switch resets.

20P7 Lockout Swichgage

Same as 20P Series. They also include a front, semi-automatic lockout for startup override. This built-in device holds the pointer away from the contact on startup. When pressure exceeds the set point, the lockout is automatically disengaged (see following pages for details).

20PG Murphygage

Gage without contact(s)




Mechanical Pressure Gauges 25DP and A25DP

Mechanical Pressure Gauges (25DP and A25DP)

The 25DP and A25DP Series (2-1/2 inch/64 mm dial) Swichgage instruments are diaphragm-actuated, differential pressure-indicating gages with a built-in electrical switch. This switch is used for tripping alarms and/or shutting down equipment. These gages are intended to monitor and indicate oil, fuel or water filter restriction and can reduce the risk of dangerously high pressure which may rupture the filter, resulting in contaminants entering the system.

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 gage 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 gage and adjustable p.s.i.d. limit switch reduces inventory and installation time. Adjustable contact lets you set the monitoring range of the gage. The contact is tamper proof and can be set only with a 1/16 Allen-head wrench. All gages are made of durable materials allowing them to withstand rugged applications. Early filter changes cost you money and increase the risk of contaminants entering the system. A filter restriction Swichgage instrument will let you know when to change the filter and maintain peak efficiency.

The A20 Series (2 inch/51 mm dial) and the A25 Series (2-1/2 inch/64 mm dial) Swichgage instruments are diaphragm-actuated, pressure-indicating gages with built-in electrical switches for tripping alarms and/or shutdown devices.

Ranges are available from 0-30 psi (207 kPa) [2.0 bar] through 0-300 psi (2.1 MPa) [20 bar].
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 gages 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 gage 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.
Gage-only models, without switches (Murphygage instrument) are also available.
A20/A25 Series applications include: engines/equipment in oil field for lube oil pressure, water pump pressure, hydraulic pressure, air pressure, etc.

Mechanical Pressure Gauges 45APE Series

Mechanical Pressure Gauges (45APE Series)

Mechanical Pressure Gauge

The 45APE Series gage instrument is a mechanical gage 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 gage 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.

Pressure Sensors and Instruments

Pressure Sensors and Instruments PD8100 Series

Pressure Sensors and Instruments PD8100 Series

The PD8100 Series eliminates pointer flutter on pressure indicating gage 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 gage 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.

  • Used on Controllers, Instruments and Recorders to Dampen Pressure Pulsation
  • Eliminate Gage Pointer Flutter
  • Aids in Providing More Accurate Pressure Indication
  • Decreases wear on a Gage’s Geared Movement



Mechanical Pressure Gauges PT167EX

Mechanical Pressure Gauges PT167EX

Pressure Sensors and Instruments PD8100 Series

The FW Murphy PT167EX is a pressure gage instrument connected to a threaded pressure diaphragm housing. The gage 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 gage with adjustable low and high pressure limit switches. When the gage 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 gage connection. The diaphragm housing is filled with a silicone fluid so that pressure against the diaphragm causes the gage 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.
