1. Wall installation, the height is about 1.2 meters, generally on the same horizontal line as the electric lighting switch of the home. 2. Installed on a wall where the surrounding air flows freely, and is not affected by other heat sources (e.g. sunlight), air flow from doors and windows, or external wall temperature, etc. 3. Advance ...

The following points should be paid attention to in the selection of intelligent thermostats: (1) Dimensions (panel size, length) (2) Enter the sensor graduation number (according to the matching sensor), display accuracy, and display resolution (3) What is the main output (selected according to the controller) ...

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

1. Electromagnetic induction (refers to the coupling of magnetism). There is a strong alternating magnetic field in the surrounding space of high-power transformers, AC motors, high-current power grids, etc., and the closed loop formed by the lines of the control system (detection, transmission, conversion, regulation, calculation, execution, auxiliary, display, etc.) is located in the ...

How it works The sudden jump thermostat is a kind of bimetal disc after constant temperature as a heat-sensitive reaction component, when the temperature of the main part of the product increases or decreases, the heat generated is transferred to the bimetal disc, and when the operating temperature is set, it acts quickly, and the contact is broken through the action of the mechanism.

The selection of thermocouples should be based on comprehensive considerations such as the scale of the operating temperature, the required accuracy, the atmosphere of the application, the performance of the measurement target, the response time and the economic benefits. 1. Selection of measurement accuracy and temperature measurement scale 1) The operating temperature is 1300-1800 °C, and the accuracy is required to be more accurate than ...

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) 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. 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. The principle of central air conditioning thermostat Mechanical thermostats can be divided into vapor pressure thermostats, liquid expansion thermostats, gas adsorption thermostats and metal expansion thermostats. Among them, the vapor pressure thermostat is divided into inflatable type, liquid-gas mixed type and liquid-filled type. Domestic...

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. ...

Take CD901 as an example, L(1) pin to 220 volt live wire, N(2) pin 220 volt neutral wire, 3,4 pins for the first output, 5,6 pins for the second output, 7, 8, 9 pins are alarm output, Finally, the three pins are connected to thermocouples or PT100 ...

1. The cleanliness and finish of the contact surface have a great impact on the working state of the contact. When the appearance of the contact is rough or there is residue 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 the residues; Add the process of residue selection, ...

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 ...

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. 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 ...

　　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, ...

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.

1. Thermostat contact contact failure Poor contact of the thermostat contacts will cause the compressor to not operate properly. If the contacts are sticky, the compressor will fail without downtime. For this, you can use a small screwdriver to open the metal shell of the thermostat, and then use a fine abrasive cloth to polish the surface of the contacts ...
