How to install water temperature and water level sensor in solar water heater

Water temperature and water level sensors can be installed from the top, side and bottom. However, it is necessary to have a special opening on the water tank for loading below, so there is generally no need to install a water temperature and water level sensor except for replacing the original one.

Most top-mounted and side-mounted water temperature and water level sensors are universal. The simplest thing is to remove the original water pipe from the overflow port on the side of the water tank (the innermost horizontal pipe can be kept). Insert water temperature and water level sensors, leaving only a little behind the pole; If installing from the upper exhaust port, pay attention to the insertion depth, so that the height of the upper electrode is slightly lower than the overflow port.

Extended data:

The sensor has to work in the water tank of the water heater for a long time, because the vacuum tube gets a lot of heat, and it transfers a lot of heat to the water tank of the water heater, so that the temperature of the water tank can reach about 100 degrees for a long time, and 130 degrees or even 150 degrees for a short time, which brings high temperature resistance to the sensor.

Sensor materials have always had defects in high temperature resistance. In the long-term air drying process, long-term water boiling process and long-term cooking process, both electronic devices and other sensor materials are prone to aging and damage.
