RKC thermostat - what should be paid attention to when maintaining the thermostat?

1. Bellows or diaphragm air conditioner thermostat 1. Fault phenomenon: poor contact or burning, resulting in the circuit can not be connected; The frequent action of the contact arc and sticking causes the circuit to be unbreakable; The thermostat in the temperature sensing chamber leaks, causing the contact to fail to operate and lose control. ...

1. There is no liquid level display or lower liquid level display When the sewage is discharged, only a small amount of condensate flows out, and it is judged that the pontoon is blocked. Treatment: Dismantle the outer pontoon and find that the pontoon is almost filled with dirt and impurities. Clean, calibrate, and return to normal. 2. The liquid level display is ...

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 ...

Wiring Warning: If the instrument fails or an error occurs, which can cause a system failure, an external protection circuit is installed to prevent such accidents: In order to prevent damage or failure of the instrument, choose an appropriate fuse to protect the power cord and input and output lines from strong power shocks. Power supply ...

1. The temperature controller control method is generally divided into two types: One is controlled by the temperature change of the cooled object, and the vapor pressure temperature controller is mostly used, and the other is controlled by the temperature difference change of the cooled object, and the electronic temperature controller is mostly used. ...

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 ...

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.

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...

　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...

CH and CD series intelligent temperature controller is a multi-functional adjustment instrument with special microprocessing, which adopts switching power supply and surface mount technology (SMT), so the instrument is delicate and compact, and the performance is reliable. The unique self-diagnosis function, self-tuning function and intelligent control function make it possible for the operator to pass the ...

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.

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 buoy level gauge is welded and installed under the guide wire At the bottom of the container, determine the position according to the requirements of the movement direction of the level gauge buoy, and weld or rivet the support under the fixed guide wire. 2. Buoy level gauge ruler installation 1. The connecting part of the ruler should be flat.

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 ...

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". ...

1. The terminal post of the thermostat is stuck and falls off Cause the compressor not to start, the thermostat dynamic and static contacts can not be disconnected, so that the compressor does not run, the thermostat contacts can not be disconnected, so that the motor of the refrigerator compressor does not stop, in addition to the balance elastic force is too weak, it can also be ...

Generally, there are three buttons to provide the need for setting, one is the Set button, press it once to enter the setting state. The other two offer upward and downward temperature adjustments, which can be adjusted to any temperature point. After adjusting to the desired temperature point, press the Set button again to confirm. 1. Turn on the smart thermostat ...

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.
