RRKC thermostats – the commissioning steps of mechanical thermostats

After heating for a while, 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 a fault, first check whether the SV value setting value is set, whether the OUT indicator of the meter is lit, and whether the No. 3 and No. 4 terminals of the meter are 12VDC output with the "multimeter". ...

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 ...

RKC thermostat operation attention · Clean the instrument only after the power is off; · Please use a soft cloth or cotton paper to remove stains on the monitor; · The display is easy to be scratched, it is forbidden to use hard object to operate the panel buttons, otherwise the keys will be damaged or scratched. 　　Key features: ...

　　The core control algorithm of the temperature regulator is PID control, P (Proportional) ratio + I (Integral) point + D (Differential) differential control. In addition to the traditional PID control algorithm, RKC also has ON-OFF control, custom parameter control, adaptive parameter control and other algorithms, ...

Fault 1, the indication is abnormal The float level gauge is not indicated properly and is a very common fault of the float level gauge. Usually there are the following manifestations: Phenomenon 1: The float level gauge in the atmospheric pressure workshop has the largest indication. Troubleshooting: The float was found to be ...

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...

(1) After 6 months to 1 year of operation, the sensor should be visually inspected and routinely calibrated. (2) Regularly check whether the sensor is bent and deformed by external force to avoid ball jamming. (3) Regularly check whether the magnetic induction switch element of the sensor is aging and failing, ...

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 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. Set temperature: Press the SET button to set or view the temperature set point. Press the SET key digital tube characters to start flashing, indicating that the instrument has entered the setting state, press the △ key to increase the set value, press the ▽ key to decrease the set value, press and hold the △ key or ▽ key The data will change rapidly, press the SET key again ...

　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...

Explosion-proof float level switch Explosion-proof float level switch, also known as explosion-proof float level controller. It is a liquid level control instrument specially designed and manufactured for use in explosive atmospheres, this product is designed based on the principle of buoyancy and the principle of lever, when the liquid level in the container changes, ...

The rkc controller was developed by Japan and is mainly used in plastics and stoves. Of course, it is also widely used in China's industry, there are many people who do not know much about the rkc controller, and some even feel unfamiliar.

1. The level gauge is adjusted normally, and it is found that the float is "absorbed" for a period of time in a certain position after it is put into use. This is mainly caused by the level gauge passing through the steel platform device and being spaced too close to the steel plate. Therefore, it is necessary to pay special attention to the level gauge to connect the pipe wall with the steel platform device.

First, the selection of the orientation of the thermostat device 1. Easy to operate locally; 2. It can include the average temperature of the local area; 3. Localities with more human activities; 4. It can avoid cold and heat sources; That is to say, the orientation of the device should be far away from radiators, away from doors and windows...

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

Programmable logic controllers (PLCs) and temperature controllers (thermostats) offer similar benefits in ensuring effective process control, achieving consistent quality, and minimizing user error in manufacturing. Since the 17th century, process control equipment has been used in a variety of forms.

The correct selection of the level gauge can ensure the better use of the level gauge. What kind of level gauge should be selected according to the physical and chemical properties of the fluid medium to be measured? What is the diameter of the level gauge, the flow range, the lining material, the electrode material, and the output current? can adapt to the ...

Many household appliances and large-scale equipment products will be installed in the use of thermostats, thermostats will be combined with the change of ambient temperature in the switch when working physical deformation, which will produce some special effects, resulting in conduction or disconnection action, in order to achieve automatic ...

1. The specific gravity of the liquid to be measured must be greater than the specific gravity of the float 2. The measured medium should not contain ferromagnetic impurities 3. The float level gauge should be installed in an unobstructed position when the float moves up and down 4. Magnets are not allowed to be close around the float level gauge, otherwise it will affect the float.
