Dear sir,
I want to monitor the temperature of the exhaust of my boat engine.
Therefore I need a kit for the monitoring of the temperature and a kit for a flashing led and piëzo sound alarm
The temperature of the exhaust is around 55⁰C.
I found your kit Mk 138 but the temperature range is from 5 to 30⁰C.
I would like to monitor in the range 40 to 70⁰C
Is it possible to change a few components in the Mk 138 kit and if so will the potentiometer still be as sensitive as in the present situation?
I hope you can help me
Kind regards,
Basically, you need an NTC of say 10K that is able to withstand 55°C or more.
Most likely, you do not need to change any resistors on the board, try it first.
If you need to change values, the board indicates which ones to change and if you should increase or decrease them.
Sorry, no values, please experiment.
