RLC thermostat - introduction to the performance characteristics of intelligent digital display controller

Model: CH402FS01-8*HN (for PECVD temperature control) 1) Single press SET: SV can be set (set temperature manually) 2) Press and hold the SET button for 2 seconds, ALI=1000 (absolute alarm temperature setting) and then press the SET button, ATU=1 (self-defining, self-interpreting a set of PID parameters) to exit ...

peculiarity 1. Thermocouple, RTD, analog and other signals are freely input, and the range can be set freely. 2. The software adjusts the full degree, the cold end measures the temperature separately, the amplifier is self-stabilizing, and the display accuracy is better than 0.5%FS. 3. Fuzzy theory combined with traditional PID method, fast control ...

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 causes the solder joint to show a breakpoint, and sometimes it is caused by the phenomenon of virtual soldering at the factory. 2. Temperature controller ...

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 ...

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.

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 ...

How liquid expansion thermostats work Liquid expansion thermostat is a physical phenomenon (volume change) that causes the material (generally liquid) in the temperature sensing part of the thermostat to undergo corresponding thermal expansion and cold contraction when the temperature of the controlled object changes, and the diaphragm box connected with the temperature sensing part expands or ...

(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, ...

There are many models of temperature controllers, and the output methods are slightly different, but the wiring principle is the same. The working principle of the thermostat: the main circuit of the power supply is directly connected to the heating device through the main contact of the AC contactor.

1. Under what circumstances should I use a thermostat to expand the module? The gradual development of the heating field is now very well recognized, and more and more users have begun to install electric heating, of course, when installing electric heating for users, they have also encountered some headaches. For example, a large area ...

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 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. According to the theory of cutting off the overvoltage, when the transformer is cut off, the current in the transformer inductance cannot be abruptly changed, and the stored magnetic field energy forms a vibration between the excitation inductance of the transformer and the ground capacitor, and the overvoltage occurs. 2. Transformer ...

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, ...

　　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. ...

In a variety of electronic control equipment, digital display has become an indispensable and important link. The electronic devices and corresponding driving circuits used for digital display are called digital displays. Commonly used digital displays include glow digital tube displays, fluorescent digital tube displays, projection ...

(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 ...

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, ...

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 ...

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: ...
