Analysis of common fault causes of RKC temperature controller

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 ...

In winter, the surface of the power plant's measuring instruments is frozen and condensed, which can lead to poisoning, fire and even explosion. Therefore, the cold and freeze protection of the appearance of the instrument is particularly important. First, the selection method (1) Choose the appearance with insulation device. According to the category of appearance ...

When using a temperature controller to control a heater, it is necessary to convert the control calculation results of the temperature controller into electricity and apply it to the heater. Electromagnetic relays, solid state relays or phase controllers are usually used for conversion. Depending on the conversion method, the output of the temperature controller is different ...

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) Size selection When replacing the thermostat, choose according to the original size; The newly added thermostat should take into account the overall coordination of the cabinet installed, too large to fit, too small to see the display, the same function of the thermostat, the price of large volume will be more expensive, small size may function expansion...

1. Confirm the angle sample first. See where the angle of the sample is today. 2. Pick up the thermostat, first confirm whether the switch of the thermostat is tight, stuck, whether the white dot falls off, whether there is sound when the thermostat contacts are in contact, and if there is no sound, there should be two possibilities! ...

Thermostat, according to the temperature change of the working environment, physical deformation occurs inside the switch, so as to produce some special effects, a series of automatic control elements that produce on-on or off-action actions, or different principles of electronic components at different temperatures and working states to give ...

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 ...

peculiarity 1. Thermocouple, RTD, analog and other signals are freely input, and the range can be set freely. 2. The software adjusts the full degree, the cold end measures the temperature separately, the amplifier is self-stabilizing, and the display accuracy is better than 0.5%FS. 3. Fuzzy theory combined with traditional PID method, fast control ...

The working principle of dry-type transformer thermostats The dry-type transformer temperature controller is a new generation of controller designed for the safe operation of dry-type transformers. The controller adopts single-chip microcomputer technology, and uses three platinum thermal resistors embedded in the three-phase winding of the dry-type transformer to detect and display the transformer.

The level gauge is composed of five parts: float, traction cable, guide pulley, hammer pointer, display ruler or magnetic flap. 1. Float: The float is welded with two stainless steel (or carbon steel) fasting cones and one stainless steel (or carbon steel) fasting cylinder.

Fault 1: The thermostat does not turn on (does not light up) Analyze the causes 1. Wrong wiring 2. The voltage of the input terminal is not enough or the input terminal is damaged by empty opening and leakage 3. Whether the cable between the panel and the power board is broken or plugged incorrectly 4. Load short circuit or open circuit, probe ...

1. Prepare the thermostat, wires, and thermal resistance, and print out the wiring diagram of the thermostat 2. Use wire strippers to strip off the wire skin, use crimping pliers, and press the wire end to the cold-pressed terminal. 3. Connect the 220V power supply to the inlet terminal of the thermostat, and connect the thermal resistance to the thermostat ...

1. Set temperature: Press the SET button to set or check the temperature set point. Press the SET button at the beginning of the digital tube character flashing, indicating that the appearance has entered the setting state, press the △ key to add the set value, press the v key to decrease the setting value, press and hold the △ key or √ key The data will change rapidly, press the SET key again ...

In temperature measurement, thermocouples and RTDs are both contact temperature measurements, and although they both measure the temperature of an object, their principles and characteristics are different. This article first introduces thermocouples, which are widely used in temperature measurement temperature control devices.

1. There is no manifestation when the power is on. For this kind of problem, first confirm whether the power supply is there and whether the power supply matches the power supply required by the thermostat, and then check whether the wiring is strong. The problem is still there, then it is the problem of the thermostat itself. 2. There is a manifestation, and the manipulation makes mistakes. The first thing to look at this kind of problem is to look at the control ...

What problems are easy to encounter in the use of PT100 temperature sensor probes? 1. Is the output signal unstable? A: Maybe it's the temperature instability of the temperature source itself, or the problem of on-site disturbance. 2. Is there a big error in the output of the transmitter? Answer: This ...

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. Lower limit deviation alarm setting: press the SET key to select and display "SLP", the green display screen displays the value of the parameter, and select the shift, increment, and decrement keys to set or modify the parameter. This parameter indicates the difference between the alarm point and the master setpoint. 2. The upper limit deviation alarm is set ...

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 ...
