REDARC EGT & Boost / Vacuum Gauge
EGT & Boost / Vacuum 52MM Gauge
The REDARC 52mm EGT & boost/ vacuum gauge is a must for your diesel turbocharged vehicle.
The G52-EU is used to monitor the exhaust gas temperature (EGT) of turbo-equipped vehicles in conjunction with a pyrometer probe. EGT is an indication of how hot the combustion process is in a vehicles cylinders. Excessive EGT can cause engine or turbocharger damage. Many conditions can result in excessive EGT (i.e. too much fuel or not enough air) and are made worse when a vehicle is pulling a heavy load, climbing or running at continuous high speeds.
The vacuum feature shows the difference between outside atmospheric pressure and the amount of vacuum present in the intake manifold. This gauge gives you a guide to the engine’s mechanical health. It can give you information about problems such as engine rings, valves, leaking intake manifold gaskets, etc. By monitoring boost, you are also able to keep the vehicle's engine components in the proper power range to achieve the most performance from your vehicle.
The gauge is supplied with a “K” type EGT sensor and electronic boost MAP sensor interface. The boost/ vacuum has a peak hold function with a display range from -12 to 23 PSI and programmable alert level between -10 and 10 PSI. The EGT function also has a peak hold function with a range from 0 to 1,000°C and is programmable between 500 and 800°C. The EGT probe has a 1/8” NPT compression fitting and is supplied with a weld in mounting bung.
The G52-EU gauge diameter requires a 52mm hole for mounting. REDARC offer a range of mounting solutions including a 2” black plastic mounting cup (GH-CUP) and one (GH-MP1), two (GH-MP2) and three (GH-MP3) hole gauge mounting panels. Radio inserts are also available for the Toyota Hilux (GH-RI05).
2.5” (GMC-2.5) and 3.25” (GMC-3.25) muffler clamps are also available from REDARC to hold the EGT probe.
The REDARC 24 to 12-volt adaptor (GA-2412V) can be used to connect this gauge to a vehicle with a 24-volt ignition and lighting supply.
- Satin Chrome Bezel
- 13 Selectable Backlight Colours
- EGT and boost/ vacuum peak hold functions
- Multiple programmable alert levels with amber or red backlight and audible beep
- Display illuminates when park lights are turned on so you can check battery voltages and discharge or charge current without turning on the ignition.
- If fitting more than one REDARC gauge, a communications link can be connected between the gauges to change the backlight colour of all at once.
Enhanced Lighting Controller*
REDARC recommends the purchase of an Enhanced Lighting Controller (GA-ELC) with this gauge. The GA-ELC is designed to enhance the lighting of your REDARC gauges as only one required for a set. It is to be used when you do not have a dimming circuit to connect your gauge to or the dimming circuit in your vehicle does not dim the REDARC gauge to your liking.
The GA-ELC also allows you to program nighttime brightness and colour of your REDARC gauges, including dimming if connected to a dash dimmer. Once programmed your gauges will change colour when turning on your park lights and back to a daylight colour when you turn them off. The GA-ELC is also 24 volt capable.
