Hello
I intend to fit a dual monitor/alarm to the exhausts on my TAMD 61A engines to avoid problems if the water supply fails.
Does any one have any knowledge of what correct exhaust temp. should be and at what level the alarm should be set to.

Thanks
 
We have “inlet pump pressure “ amongst many other deltas being monitored .
Theres an alarm if it drops , but the ECU also knows the rpm, and can figure out what the pressure should be @ 600 rpm and 1750 rpm .
 
silvercloud, how is that going to work? what type of sensor and where are you meant to fit it?

I was worried about the same thing and following some research and testing, decided to fit sea water pressure sensors reporting well, the pressure of the sea water within the engine. Decided to fit the sensor at the inlet endcap of the first heat exchanger after the impeller. It means that:
if pressure drops, inlet issues, impeller shreaded, seacock closed or strainer blocked.
if pressure rises, blockage AFTER this point in the system.
for good measure I also have EGT probes just before the mixer, but they honestly are not going to be of any help if seawater cooling is blocked...
 
There is a temperature sensor available that goes into the exhaust hose immediatly after the turbo.
If the water injection into the exhaust fails the temperatur rises and the alarm will sound.
You do not have to remove the hose as a collar is supplied that clamps round it and just drill a hole for the sensor
The temp. values can be set for each engine.
Sounds like a good system to me.
 
yep, should be simple and good, however I cannot help on your query no idea how hot the gas/water mix is, I'm afraid it's going to be trial and error thing!

I fitted one of the cheep eBay ones with a digital temperature readout and fitted the sensor on the outside of the exhaust injection fitting just before the flexible hose using a hose clamp. Ran at full throttle on a sea trial and watched the temperature rise then stabilise. Note that temperature then set the alarm temperature 10 degrees higher.

don;t know if literature mentions anything, I'd be tempted to drill the hole for the sender on the "top" side of the hose, so that when engine off, seawater and other sh1t wont spend lots of time draining onto this. Lambda sensors in racing cars are also recommended to be on the top side so that fumes/unburnt fuel, whatnot wont drain into the sender (similar logic, different materials functions though)
