PVCAN series CAN J1939 Engine Gauges

PowerView PVCAN is a series of intelligent gauges designed to display easy-to-read information broadcast over the SAE J1939 communications. These gauges are wired directly to the J1939 CAN bus, without the need of a display, interface or other device to drive them.

PVCAN gauges include features such as a smooth stepper motor operation for the 270° sweep pointer, environmental sealing to IP68 including two Deutsch DT style connectors molded into the casing, and green LED back lighting. They are available for standard 2-1/6" (52mm) and 3-3/8" (86mm) diameter hole sizes. In addition, their polycarbonate cases incorporate a "D" shape allowing panel cutouts that eliminate gauge rotation during installation.

All PowerView gauges can be powered by 12 or 24 VDC systems.

PVA series analogue gauges
PVAA audible alarm

PowerView™ PVA series premium gauges provide highly visible, analogue display of J1939 engine parameters, including oil/gearbox pressure, coolant temperature and engine speed.

Engine data is transmitted from the PowerView™ PV101 and PV750 modules to the gauges via a twisted pair RS485 Modbus link. PVA gauges are available with selection of lens and bezel styles and colours. All models feature IP68 environmental sealing with Deutsch DT style connectors and casing, and dimmable green backlighting.

PVA35 series (3.6"/92mm face) models are used for tachometer and speedometer indication; PVA20 series (2.3"/59mm) gauges are used to indicate engine/gearbox pressures, temperatures and other parameters. The PVAA20 is a matching audible alarm, with operator-initiated, timed mute feature and outputs for driving external alarm devices.

PVM series PowerView analogue gauges

The PowerView™ PVM series is a range of cost effective, easy-to-read gauges for use with electronically controlled (SAE J1939 CANbus) engines.

PVM gauges operate with the PowerView™ range of display modules, via a single RS485 twisted pair MODBUS RTU serial link. The gauges can be daisy-chained using quick-connect harnesses.

The major feature of the PVM gauges is their balance between design and functionality. These modern gauges offer a selection of bezel styles and colours. The PVM gauges also include smooth stepper motor operation with 270° sweep pointer, an environmentally sealed case with two Amp Mini Universal Mate-N-Lok connectors molded into the casing, and green LED back lighting.

20P & 25P series Pressure Swichgauge

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

Features:

Combination indicating gauge and limit switch
Critical pressure limit switch is visible and adjustable (most models)
Switch can activate alarms and/or shutdown equipment
Exceeds SAE standards

A20P & A25P Series Pressure Swichgauge

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

20V, 25V, A20V, A25V Vacuum Swichgauge

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

20DP, 25DP, A20DP, A25DP
Differential Pressure Swichgauge for Filter Restriction

The 20DP and A20DP series (2 inch /
51 mm dial) and the 25DP and A25DP series (2½ inch/64 mm dial) Swichgauge® models are diaphragm-actuated, differential pressure indicating gauges with a built-in electrical switch. The Swichgauge® indicates the pressure difference between 2 inlet ports, and provides a closing contact when the user-set limit is exceeded.

These gauges are intended to monitor for oil, fuel or water filter restriction: they can reduce the risk of dangerously high pressure which may rupture the filter, resulting in contaminants entering the system; they can also trigger automatic flushing (backwash) in irrigation systems.

20/25VWC, A25VWC Air Filter Restriction Swichgauge

The VWC Series Swichgauge® instruments are direct reading gauges for use with dry air filters. As the filter deteriorates, air inflow will decrease creating increased vacuum between the air filter and the carburettor. The vacuum is monitored by the Swichgauge®, which gives a visual readout of the filter condition. A built-in adjustable limit contact can operate an alarm to alert the operator when it is time to service or replace the air filter element. Murphygauge® indicating-only models are also available.

20BPG & 20BVG B-Series Murphygauge

The B-Series Murphygauge® is a high quality, diaphragm-actuated indicating gauge. Built by Murphy with the same heavy-duty design as the standard 20 series and 25 series, the B-gauge is more compact and is the optimum instrument for gauge-only applications. It has a high impact polycarbonate lens, sturdy steel case, and a polished, low-profile stainless steel bezel. Accuracy and protection from moderate over-pressure is assured by a unique, unitized diaphragm chamber, superior quality materials, and the design of the gauge movement.

OPL series 4.5 Pressure Gauge and Swichgauge

The OPL series Pressure Swichgauge® instruments are combination pressure indicating gauges with adjustable low and high limit switches. Limit switches can be wired directly to electric pilot circuits to operate alarms, shutdown or start/stop of engines and electric motors.

Base models:

Features:

SDB Series Direct-Mount Temperature Swichgauge

The SDB series are direct-mounting temperature Swichgauge® 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 Swichgauge® allows you to adjust the limit switch trip point. Pointer movement is actuated by a bi-metallic sensing element.

Exhaust Pyrometers and Pyroswitches

The single and dual port pyrometers monitor exhaust temperatures in all types of engines. The dual port pyrometers are for use with
V-type engines, allowing side-by-side comparison of left and right exhaust temperatures.

Both pyrometers feature an easy-to-read illuminated dial with scales in both Celcius and Fahrenheit. They require no outside power (except for dial lighting). Spring loaded jewels and alloy pivots increase durability. Murphy offers pyrometer accessories such as thermocouples and wire lead assembly. A range of pyroswitches is also available for automatic warning or shutdown on high exhaust temperature.

Features:

• Single or dual port reading
• 2% accuracy
• Sealed construction
• Thermocouple measurement with ambient temperature compensation
• Easy to read scales
