1. The upper and lower types of the induction probe of the solar water heater have no effect on the response of the instrument. 2. The water temperature sensor mainly uses the thermistor and water induction to produce a temperature display, which is actually the same as that on the air conditioner, but the outside of the brain is added with a layer of waterproof silicone. As for the water level display, it is based on endpoint-to-endpoint sensing.
As for the four lines that come out, two are for the water temperature and two for the water level. 3. The solar water heater is a device that converts sunlight energy into heat energy, and heats water from low temperature to high temperature to meet the use of hot water in people's life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat panel solar water heaters according to their structural form, mainly vacuum tube solar water heaters.

Solar water heaters.
The probe, i.e. the water temperature sensor, is damaged and cannot be repaired, but can only be replaced. Reasons for damage to the water temperature sensor: 1. Because the temperature in the solar water tank is 100 degrees Celsius for a long time.
Above, the temperature sensor.
When placed in a water tank, exposed to air, boiling and steam, the sensor's electronics are susceptible to aging or damage. 2. After the water heater is used for a period of time, there will be a lot of scale attached to the electrode and temperature sensing block of the temperature sensor, which will affect its normal output. 3. Lightning strikes make the sensor acquisition circuit fail.
Replacement method: The probe of the solar water heater is divided into two types: side-mounted and bottom-mounted. The lower position means that the sensor is at the bottom of the water tank, and the nut can be removed by unscrewing it; Side-mounted means that the sensor is near the exhaust pipe of the water tank, and it can be withdrawn with a little force.
After removing the original probe, cut off the signal cable connector. Attach the new probe and connect the signal cable.
-
It varies depending on the model.
Different models of the same brand may also have different solar energy.
However, in general, the outlet bucket has an upper reserved opening, and most of the solar energy is an upper side entrance.
Therefore, even if it is not top-mounted, it can be modified to top-mounted.
-
Whether the solar bottom sensor and the side sensor can be seen are not the same mode of the two sensors, if they can be universal, but the installation position is different. The versatility of different manufacturers is even worse.
-
The under-mounted sensor is generally threaded, and the sensor can be removed with a wrench and replaced with an upper one.
Unless your solar wood has upper exhaust outlets and side exhaust holes, use the undermount sensor.
If there is a downward sensor during installation, you can also install the upper sensor downward, provided that your solar overflow pipe is alive, remove the overflow pipe, pass the signal line of the sensor out of it, and then install the overflow pipe. If you want to replace the sensor, you need to remove the overflow tube.
Replace the water level sensor probe of the solar water heater:
1.The water temperature sensor is in the lower part of the water tank, and you can take it off by unscrewing the nut on the side of the connector, and take it out slowly.
2.The water level sensor in the container transmits the perceived water level signal to the controller, and the computer in the controller compares the measured water level signal with the set signal to obtain a deviation, and then sends it to the water supply electric valve according to the nature of the deviation"On""off"to ensure that the container reaches the set water level.
3.After the water inlet process is completed, the computer in the temperature control part sends out to the electric valve that supplies the heat medium"On"The system then begins to heat the water in the container.
4.When it comes to the set temperature. The controller issued a command to close the valve, cut off the heat source, and the system entered the insulation state.
In the process of programming, to ensure that the system does not reach the safe water level, the electric control valve that controls the heat source does not open the valve, so as to avoid heat loss and accidents.
-
The wiring of the same manufacturer is the same, as long as the original sensor is not bad after changing the controller, you can continue to use it, in fact, the side-mounted type is just the opposite of the bottom-mounted type, one is from the top to the bottom, and the other is from the bottom to the top.
-
This has to be made clear: sideways or downward?
The side-mounted ones can be pulled out slowly.
The lower one is screwed with a wrench, and this wire tooth is the same as an ordinary bolt.
-
If the solar probe can't be pulled, don't be hard, and you have to figure out how to get it out.
-
Is it stuck inside, you can take a look at it from the maintenance master.

1. You will find something like a rubber stopper on the too energy, hold the song like a rubber stopper and swing it back and forth and drag it down, you don't need to use a lot of strength when dragging, you can shake it gently, and you need to pay attention to the four or two lines when you choose it. Next, install the solar sensor that you just bought that meets the standard and meets the model.
2. Another way is not to remove the previously broken sensor, you can choose to buy a set of instruments online or in a physical store, which also contains sensors and solenoid valves, and then insert the newly bought sensor into the exhaust hole at the top of the water tank, so that it can be used again, and the replacement method is also very simple.
-
The analysis is as follows:
1. There is a rubber stopper similar to the plug of a thermos, hold the rubber stopper and swing back and forth, and pull it down.
2. You can also do not dismantle the original sensor, and then buy a set of instruments online including solenoid valves and sensors, which is 100 yuan, and insert the sensor into the exhaust hole above the water tank, which is very convenient to use.
Extended Materials. Like air velocity, water velocity can also be measured through orifice plates. However, the main purpose of measuring water velocity is to determine the amount of heat. There are many types of heat meters on the market that can measure flow rates, and they all work on different principles.
