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. 4. Instrument power cord ...

(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) For the indicator, also known as the display panel, the indicator plays the role of local display, convenient for long-distance observation of the actual situation of the liquid level, the indicator is generally bundled with the pontoon, easy to install. (2) It is a magnetic float, which is located in the pontoon and is in direct contact with the liquid to be measured, ...

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 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; Leakage of thermostat in the temperature sensing chamber, causing the contacts to fail to operate and lose control ...

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. 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. Mechanical The sensitive gas diaphragm box or thermal bimetal sheet is used as the temperature sensing element to form the temperature control switch of the mechanical contact. This kind of thermostat is more in the European and American markets, and only a few domestic manufacturers promote such products. Mechanical floor heating thermostats usually have contact currents of no more than 8A, which are suitable for ...

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: ...

(1) Categorize by display color 1. Monochrome display There are two types of displays: multi-grayscale monochrome display and VGA multi-frequency monochrome display. These displays are small, lightweight, clear and inexpensive, making them suitable for highly mobile workplaces. 2. Color ...

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 ...

1. What is the principle of the sudden jump thermostat? The sudden jump thermostat is a kind of thermostat, which is a series of automatic control elements that are physically deformed inside the switch according to the temperature change of the working environment, resulting in some special effects and on-off action. Sudden jump ...

　　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. ...

1. The three wiring methods of Pt100 RTD are different in principle: The two-wire system and the three-wire system are measured by the bridge method, and the relationship between the temperature value and the analog output value is given after ***. There is no bridge on the four wires, it is completely just sent with a constant current source, measured by a voltmeter, and the test is given after *** ...

1. Support welding under the guidewire: According to the direction of the movement of the buoy of the level gauge, determine the position at the bottom of the container, and fix the guide bracket (piece 1) under the welded or riveted steel wire 2. Install the guide rail joint. (1) Straighten the wire forcefully and fix it at the lower support, taking care not to ...

　　A relay is an electrical appliance that works automatically. When the amount of electricity such as voltage, current, and frequency or non-electricity such as temperature, pressure, and rotational speed is input to the relay, and when the specified value is reached, the contacts of the relay connect or cut off the circuit that controls or protects it. Relays are widely used in motor control and power ...

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 ...

1. In which room should the thermostat be installed? It is very important to choose a reasonable location to install the thermostat, which will directly affect the work of the wall-hung furnace in your home, the main living room (living room) should be your best choice, you can also install the thermostat in the bedroom according to your personal needs.

1. Float level gauge is an instrument that relies on the principle of buoyancy to measure the liquid level. Usually by means of a float in conjunction with a scale, the observer can visually read the height of the liquid level. Advantages: fast and intuitive reading; Low price; Easy to install.
