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 ...

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

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.

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

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 ...

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 ...

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 ...

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 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 ...

1. Set temperature: Press the SET button to set or view the temperature set point. Press the SET key digital tube character start flashing, indicating that the appearance 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 The appearance will return ...

Pop-up thermostat Bimetal Disc Jump Thermostat is a kind of bimetal sheet after constant temperature as a heat-sensitive reaction component, when the temperature of the main part of the product rises, the heat generated is transferred to the bimetal disc, and when the operating temperature is set, it acts quickly, and acts through the mechanism to act as a contact ...

In general, the following points should be followed when installing a float level timer: 1. In order to prevent the float from sliding or hitting the sealed tube at high speed during transportation, causing the measuring belt to fall out, the instrument is fixed at the bottom of the sealed tube with a clamp before leaving the factory, and the magnet is on the top of the sealed tube.

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...

The float level gauge is widely used, mainly used in petroleum processing, food processing, chemical industry, water treatment, manufacturing, electric power, papermaking, metallurgy, ships and boilers and other industrial automation processes to measure and control the level. 1. Pay attention to the specific working conditions. As introduced ...

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 ...

In most cases, in Europe, the thermostat is a necessary accessory for the wall-hung boiler, and the two are delivered to the user at the same time, and most of the thermostats equipped are intelligent thermostats. In China, nearly 95% of the wall-hung boilers that have been installed in operation and are being installed and debugged and ready to be put into use are not equipped in advance.

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, ...
