Temperature Alarm Gauges Product Information

Overheating can permanently damage your engine and transmission

Monitor and provide early warning of overheating with a visual and audible temperature alarm you can set

Our gauges allow you to monitor and set alarms for both the engine block and transmission housing temperatures during all driving conditions. There are gauge models available which also monitor coolant level and EGT temperature.

The gauge uses digital technology and has a full colour screen to display temperatures, settings and alarms.

For example: With our Engine and Transmission Temperature Gauge you can set SAFE engine and transmission temperature levels which the display will show in GREEN. By setting the MAXIMUM temperature levels, an audible alarm and flashing RED display will be triggered if the maximum temperature is exceeded. If the temperature is above SAFE but below the MAXIMUM, the display will show an AMBER warning. If the engine or transmission temperatures are below freezing, the gauge display will show BLUE. The gauge can also show the highest engine and transmission temperatures reached since the gauge was powered on.

The display and settings can be in Celsius or Fahrenheit (option set via the Menu and Settings buttons).

 

Why do you need a gauge to display and alarm engine and transmission temperatures?

Standard temperature indicators sometimes provide engine temperature information. But if you’re focused on driving, you may miss the indicator going into the RED until it is too late and your engine or transmission is damaged.

Often standard indicators only measure the engine coolant water temperature. If your engine water is lost or the level drops for any reason, many indicators won’t show that the engine is overheating. You may not be aware that your engine is being damaged.

Most vehicles do not have an indicator showing transmission temperature. If you are 4WD’ing or towing a caravan, boat, trailer etc, your transmission and engine will be working hard, increasing the temperature. The temperature of the transmission can also become excessive during high speed highway driving. If you are not aware of your actual transmission temperature, you have no way of knowing whether it is being damaged by excessive heating.

This gauge allows you to monitor and set alarms for both the engine block and transmission housing temperatures during all driving conditions. The temperature gauge uses digital technology and has a full colour screen to display temperatures, settings and alarms.

You can set SAFE engine and transmission temperature levels which the display will show in GREEN. By setting the MAXIMUM temperature levels, an audible alarm and flashing RED display will be triggered if the maximum temperature is exceeded. If the temperature is above SAFE but below the MAXIMUM, the display will show an AMBER warning. If the engine or transmission temperatures are below freezing, the gauge display will show BLUE. The gauge can also show the highest engine and transmission temperatures reached since the gauge was powered on.

 

The gauge dimensions and bezel conform to the 52mm diameter automotive gauge standard, so the gauge can be easily mounted in gauge housings or pods.  A Dash Gauge style which can be installed on any flat surface is also available.

There are two gauge buttons - Menu and Settings. The steps required to set the temperature alarms, adjust the screen brightness etc are easy to follow.

 

How it Works

 The gauge receives continuous engine and transmission temperature measurements from  digital temperature sensors mounted directly on the engine block and transmission housing.

Each digital temperature sensor can measure temperatures from -55°C to +125°C (-67°F to +257°F). The gauge displays temperatures in one degree increments.

The gauge checks the measured temperature against two temperature levels (SAFE and MAXIMUM) which are set separately for the engine and transmission.

  •  SAFE temperature. An engine (or transmission) temperature at or below SAFE is normal operation.

  • MAXIMUM temperature. An engine (or transmission) temperature at or above the MAXIMUM will flash a RED display and trigger the audible alarm. The alarm will also be triggered If the gauge cannot receive a temperature reading from either sensor. The audible alarm can be cancelled by pressing either the Menu or Settings button or can be turned off using the gauge menu/settings.

The SAFE temperature setting must be lower than the MAXIMUM temperature setting. An engine or transmission temperature in the range between SAFE and MAXIMUM is displayed as a warning in AMBER. By pressing the Settings button, the gauge will display the highest engine and transmission temperatures reached since the gauge was powered on.

The gauge display icons, settings and colours used are clear and easy to understand. One glance at the gauge and, if the display is GREEN, all is normal.

 Options

  • Celsius and Fahrenheit temperature standards are supported. .

  • Two waterproof digital temperature sensors marked engine and transmission (blue stripe on the sensor) are available with the gauge. 

  • The optional coolant sensor attaches to the outside of the plastic coolant bottle at the level you decide. The sensor technology detects if there is coolant inside the bottle up to that level or not. The gauge checks the sensor and triggers both a visual and audible alarm if the sensor detects there is no coolant.  There is also a red light indicator on the sensor which shows whether the sensor has detected the coolant.  Smart technology in the gauge minimises false alarms if the coolant is sloshing in the bottle.

  • The optional EGT sensor is capable of reading temperatures as high as 1024 °C (or 1875 °F) and uses a K type thermocouple probe (with digital output) which is mounted in the exhaust pipe stream.

  • Replacement sensors or sensors with longer cables are also available by contacting gaugeinnovations.

 


The gauge has been designed, developed, manufactured and extensively road tested in Australia. It is backed by a 12 month, return to manufacturer warranty against manufacturing defects.

The firmware, icons etc can also be modified to suit particular requirements. If you have a special requirement or a suggestion for improvement, contact us by email at gaugeinnovations.
