As a secondary instrument commonly used in sensors, it is very important to operate and use it correctly. Applications such as level control, temperature control, pressure control and parameter value display of measured variables. ...

　　The power indicator is normal, but the temperature control meter has no on-screen display. This kind of fault is mostly caused by the heating of the voltage regulator element (7805 or 7812) of the temperature controller during long-term use, resulting in a break point in the solder joint, and sometimes a virtual soldering occurs at the factory, resulting in re-soldering. ...

　High-temperature melt pressure sensors, transmitters, and high-temperature melt pressure gauges are special equipment in extrusion processing. On the production line, melt pressure sensors play an important role in improving melt quality, increasing production safety and protecting production equipment. Use...

1) The LCD interface is too large or the display symbols are not proportional or standard. 2) The terminal blocks or circuits (components) that control the output cannot withstand large currents. 3) The cable of the external sensor (ground probe) is a thin and flexible wire, which cannot be inserted into the embedded pipe, and it is also a hidden danger for future maintenance. ...

1. Under what circumstances should I use a thermostat to expand the module? The gradual development of the heating field is now very well recognized, and more and more users have begun to install electric heating, of course, when installing electric heating for users, they have also encountered some headaches. For example, a large area ...

1. Heating for a period of time, the temperature does not change. Displays the ambient temperature of the site at all times (e.g. room temperature 25°C) In case of such failures, first check whether the SV value setting value is set, whether the instrument OUT indicator is lit, and whether the No. 3 and 4 terminals of the "multimeter" measuring instrument have 12VDC output.

1. Electrical parameters: (1) VDE, CQC, UL, TüVAC250V 50-60Hz 10A (resistive load) (2) ULAC125V 50Hz 15A (resistive load) 2. Operating temperature range: -50-270°C (optional), temperature accuracy: ≥ ±2°C 3. Reset and action ...

1. Grounding method: It is connected to the grounding metal parts of the equipment through the metal cover of the thermostat. 2. The thermostat should work in the general indoor environment where the relative humidity of the air is not more than 90%, and there are no corrosive gases, flammable gases and conductive dust. 3. The thermostat adopts contact ...

How it works The sudden jump thermostat is a kind of bimetal disc after constant temperature as a heat-sensitive reaction component, when the temperature of the main part of the product increases or decreases, the heat generated is transferred to the bimetal disc, and when the operating temperature is set, it acts quickly, and the contact is broken through the action of the mechanism.

1. The cleanliness and finish of the contact surface have a great impact on the working condition of the contact. When the surface of the contact is rough or there is excess material on the contact, it is easy to cause arcing and reduce the life of the contact. Therefore, the parts cleaning process should be improved to eliminate excess materials; Increasing the process of screening excess materials, ...

1. Used to control fan coil unit, electric valve, damper and other equipment; 2. The switch adopts toggle type, which feels comfortable and has a long life; 3. Set the temperature by twisting (the temperature range can be limited); 4. The thermostat can be installed directly on the wall or on the standard junction box; ...

1. The temperature setting is set by the knob, which is convenient and intuitive 2. It can be directly installed on the standard junction box on the wall. 3. Beautiful appearance and reliable performance. 4. The switch adopts toggle type, which feels comfortable and has a long life. 5. It can control two-wire or three-wire electric (ball...

Principle of electronic thermostat: The electronic temperature controller (resistive type) is measured by the method of resistance temperature sensing, and generally uses platinum wire, copper wire, tungsten wire and semiconductor (thermistor, etc.) as the temperature measurement resistor, which has its own advantages and disadvantages. Household Air Conditioner Temperature Controller ...

The temperature controller is an electrical switchgear that controls the temperature of an air-conditioned room. The temperature range in the air-conditioned room controlled by the temperature controller is generally 18°C--28°C. The temperature controller commonly used in window air conditioners uses the principle of pressure to push the contacts on and off. Its structure consists of bellows ...

First, the use of electronic temperature controller The electronic temperature controller (resistive type) is measured by the method of resistance temperature sensing, and generally uses platinum wire, copper wire, tungsten wire and semiconductor (thermistor, etc.) as the temperature measurement resistor, and these resistors have their own advantages and points. Home Air Conditioner ...

1. Take out the room temperature controller, and then connect the power supply terminal of the temperature controller to the power supply according to the terminal diagram of the temperature control chart 2. Then take out the temperature sensor that comes with the temperature controller and detect it 3. According to the temperature controller terminal, the temperature sensor is connected to the controller's transmission.

1. The power indication is normal, but the temperature controller has no screen display. Most of this fault is caused by the heating of the voltage regulator element (7805 or 7812) on the thermostat during long-term use, which leads to the breakpoint of the solder joint, and sometimes it is caused by the phenomenon of virtual soldering at the factory, and the main re-soldering can be done. 2. Temperature controller ...

The thermostat shows a nonlinear relationship between the temperature and the actual temperature deviation: (1) The input type of the thermostat is selected incorrectly; (2) There is no calibration or calibration error in the analog input; (3) There is interference in the thermostat; (4) There is interference with thermocouples; (5) The use of quality is not ...

1. Do not wipe with acidic, alkaline and other corrosive liquids and water-containing rags when cleaning, so as not to damage the temperature controller and affect its normal use. 2. Do not decorate and cover the temperature controller. The thermostat has a built-in temperature sensor to sense the outside temperature. Therefore, Wen ...
