Technical Information

 

The Engine Watchdog TM4 Twin Sensor Marine is an invaluable piece of equipment for your marine enbgines –

  • TM4 Twin Sensor Marine uses the most reliable monitoring method
    All engines radiate heat to their outer casing at a constant rate (air cooled engines depend on it).The TM4's electronic 'Easy Fit' heat sensor simply fits like a washer under any suitable bolt that is close to the cylinder head or engine block. Here it accurately monitors the engine metal temperatures and if overheating is detected for any reason, the TM4 alarms with an alarm light, loud buzzer and 'Stbd Hot' or 'Port Hot' message.
  •  
  • The TM4 Twin Sensor Marine tells you the exact temperature of both your engines
    Many factory fit gauges indicate normal after you cruise just a few nautical miles and then do not alter on even the hottest days. Obviously the temperatures of both engines are constantly altering as you travel at varying speeds and in varying conditions, yet the gauges are not responding. This is because they have a 'flat spot' around the normal mark and will not move until something is very wrong, often once it is too late. The TM4 Twin Sensor Marine has the sensitivity required to display every temperature change for both your engines as they occur and in an emergency will alert you before your existing console gauges have even moved.
  •    
 
  • You can program the TM4's alarm sensitivity to suit each engine
    With a TM4 Twin Sensor Marine you don't even need to know your engine's temperature specifications to set the overheating alarm. You simply note the highest temperatures your engines reach during normal cruising and then set the audible alarm to go off at a few degrees higher by pressing the button on the front. You get to set the alarm sensitivity for the starboard and port engines indendently, and it's no harder than setting an alarm clock.   If the alarm goes off while either engine is working hard, you can simply press the front button to stop the alarm, or give it another press to increase the alarm temperature for that particular engine.
  •  
  • The TM4 Twin Sensor Marine is very easy to fit
    TM4's can be fitted by any home handyman. The main unit fits under or inside the boat's dashboard (Compact size - 80 x 30 x 60 mm, plus mounting tabs). The 'Easy Fit' temperature sensors take a few seconds to fit, bolting one to each engine. The power just plugs into the cigarette lighter socket or it can be hard wired to your boat's electrical system. TM4 Twin Sensor Marine suits 12 or 24 volt systems.

  •  
  • The TM4's sensor cannot cause coolant leaks, or void the engine's warranty
    The TM4 Twin Sensor Marine is perfectly safe to fit because it does not require you to break into the cooling system in any way.
