CruzPro ETM20 Engine and Exhaust Temperature
||The ETM-20 Engine and Exhaust
Temperature Monitor and Alarm uses modern electronics and a reliable solid
state temperature sensor to accurately monitor the temperature at any
point it is attached. The alarm is factory pre-set at 90 degrees C (194
deg F) but can be easily adjusted with a small screwdriver over a range of
50 deg C to 125 deg C (122 to 257 deg F). When the ETM-20 detects an
over-temperature condition it sounds a built-in 85 dB audible alarm. The
alarm will continue to sound for the duration of the out-of-limit
condition, or until the reset button is pressed.
If the alarm is silenced by the use of the reset
button, the ETM-20 will automatically arm itself again as soon as the
temperature falls below the alarm set point. The ETM-20 draws only 0.012 amps at
12 VDC and can be connected to an external alarm (LA-20) to provide 105 dB of
volume, if desired.
