Precautions for the selection of RRKC thermostats

1. Select the appropriate level gauge First of all, it is necessary to choose the appropriate level gauge. The following factors should be taken into account in the selection of a level gauge: Measure the properties of the medium: e.g., temperature, pressure, viscosity, corrosiveness, etc. Measuring range: i.e. the height range of the liquid ...

1. First of all, determine the set temperature of the thermostat and make sure that it is the same as the temperature you need. 2. Recognize the operating form of the thermostat, usually there are two forms of cooling and heating, and choose the corresponding form according to the demand. 3. Acknowledging the operating condition of the thermostat, usually with active ...

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) It is a display of the common cathode. It uses the principle of the positive electrode as the segmented input, with the ground wire as the common output, and the segmented input is valid as a high-level input. 2) It is a display with a common anode. It uses an anode as an aggregate input, and in contrast to the common cathode, the segment is effective at a low level output ...

The first output method is relay output, which is output for temperature control through the switching signal of the relay on/off, which is used to directly control the load less than 5A, or directly control the contactor and the intermediate relay, and control the high-power load externally through the contactor. The second ...

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. ...

Fault 1: The device does not display after powering on Solution(s): First of all, check whether the terminals of the device have been connected to the neutral live wire, and make sure that the neutral live power supply can work normally. Then start to check whether the cable between the LCD motherboard and the device drive power supply is ...

Wiring Notes: 1. For thermocouple input, the corresponding compensation wire should be used. 2. RTD input, 3 wires with low resistance and no difference should be used. 3. The input signal line should be far away from the power line of the instrument. Power supply and load lines to avoid noise interference. ...

1) For RTD input, 3 wires with low resistance and no difference should be used. 2) The input signal line should be far away from the power line of the instrument, the power supply line and the load line to avoid noise and annoyance. 3) The power cord of the instrument is generally annoyed by the power supply. 4) Instrument complement ...

When transporting and unpacking, it is necessary to avoid excessive shock and vibration; The installation should be firm and reliable, and the pontoon should be installed vertically to prevent the pontoon from colliding with the interior wall of the pontoon; When the pontoon is hooked, it should not swing or pull and compress sharply, so as not to damage the sensor and reduce the accuracy of the instrument; ...

First, the temperature does not appear 1. Fault with the temperature sensor If the temperature probe of the temperature sensor breaks or the wire is broken, the sensor does not have a digital display when the temperature sensor is connected, but only shows the "----" and sounds an alarm.

1. Setup (XMT201-D): Press the SET button for 3 seconds to enter the inner parameter setting state. E: This parameter is the advance of heating stop when P = 0, when P is not equal to 0, the instrument is the intelligent PID working mode, and when P is not equal to 0, the E parameter is meaningless. 2.P: is the proportional band, that is, the proportional ...

(1) Before use, first check whether the level gauge is within the verification cycle, otherwise, it should be calibrated, and replaced in time if it is unqualified. (2) The sensor should be installed horizontally, and the length of the lower entry should meet the technical requirements. (3) The connection between the sensor and the explosion-proof junction box should be tightened and tightened.

1. Thermostat output control power: The thermostat output control power is the first issue to consider when choosing a thermostat, which is related to the safety and stability of use, and may cause serious consequences if not selected properly, such as: fire. Thermostat products are marked with output control voltage and current, and the ...

Direct transformation method The direct conversion method is to synthesize the "output voltage" through the continuous chopping of the input voltage, which can be divided into coordinate transformation method, harmonic injection method, equivalent conductivity method and scalar method, although all these methods have certain advantages, but also have certain problems, ...

Mechanical thermostat mainly refers to a temperature control method that adjusts refrigeration by rotating the button, with an expanding thermostat, which will automatically expand and contract according to the change of temperature, so as to control the power supply, the most primitive type, and the structure is relatively simple. Advantages of mechanical thermostats: ...

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! ...

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 ...

1. Turn on the power supply of the smart thermostat, and the temperature displayed on the screen is the temperature at that time. Because the sensor is not in contact with other devices, but is directly exposed to the air clock, this is the current temperature: 31 degrees Celsius, which is not too hot. 2. At the bottom right of the display screen is the "starting temperature" setting ...

1. Bellows or diaphragm air conditioner thermostat Fault Symptom: Poor contact or burning, resulting in the circuit cannot be connected; The frequent action of the contact arc and sticking causes the circuit to be unbreakable; The leakage of the thermostat in the temperature sensing chamber causes the contact to fail to operate and lose control ...
