Will the reading change if I decrease the probe length of the water thermostat?

I need to read the water temperature, the problem is the probe of the water thermostat is too long.

the pipe is 2 inches in diameter while the thermostat is 4 inches long.. So If i cut the thermostat

will the thermostat be broken or will the reading be abnormal already.Will the reading change if I decrease the probe length of the water thermostat?Often the thermometer (that is what I think you mean to get a reading) or a thermostat will be placed in a well in the pipe. That way it can be removed easily without opening the pipe. The well maybe diagonal along the length of the pipe. This means that the 4 inch length can be fine.



There will always be some difference due to the external and internal temperature difference that the thermometer is measuring. If the outside air is warmer than what you are measuring, some of this heat ends up heating the thermometer. The more that the thermometer is immersed the better, within reason.



If it is wholly immersed, it would need to be properly sealed, which they rarely are. The top part where the wires come out are best kept out of any water etc.



Cutting it will destroy it.Will the reading change if I decrease the probe length of the water thermostat?No ,cutting the thermostat may damage the bi metal thermostat(it will not Read at all),better to replace a suitable length thermostat ,it may be cheaperWill the reading change if I decrease the probe length of the water thermostat?You are confusing term although the first answer is sort of still valid - a thermostat is a switch that is either on or off based on the temperature - you don't get a %26quot;reading%26quot; off of it other than on/off. Readings are given by thermometers or thermocouples and yes, either one will be damaged/destroyed by cutting them off. Normally, mounting a long temperature measuring device so that only part of it is immersed will produce readings that contain an error of a few degrees in the direction of the place (i.e. warmer if measuring cold temps indoors, cooler if measuring temps hotter that the air temp.)
