RK Thermostat - The working principle and device precautions of liquid expansion thermostat

The core control algorithm of the thermostat is PID control, P (Proportional) + I (Integral) integral + D (Differential) differential control. In addition to the traditional PID control algorithm, RKC also has ON-OFF control, self-tuning parameter control, adaptive parameter control and other algorithms, temperature control ...

The terminal post of the thermostat is stuck and falls off Cause the compressor not to start, the thermostat dynamic and static contacts can not be disconnected, so that the compressor does not run, the thermostat contacts can not be disconnected, so that the motor of the refrigerator compressor does not stop, in addition to the balance elastic force is too weak, it can also be ...

Mechanical thermostats are suitable for indoor temperature control in industrial, commercial and residential buildings. The mechanical thermostat uses an inflatable diaphragm box to sense the temperature and compare it with the user's set temperature to automatically control the air conditioning equipment to achieve the purpose of indoor constant temperature. For commercial, industrial and civil construction, available ...

1. Sensor type (this is based on the actual sensor used) 2. Upper and lower limit range (usually marked on the sensor) 3. Output range setting (current or voltage signal output) 4. Alarm value setting 5. Communication parameter setting (if no point 3 is set, ...)

The main technical indicators of RKC thermostat · Input: various thermocouple (TC), RTD standard current and voltage signals (see input type table); · basic error: 0.5% of the input full-scale ±±1 word; · Resolution: 1°C, 0.1°C; ...

1. Welding and installation of the lower support of the guide wire: determine the position at the bottom of the container according to the requirements of the movement direction of the float of the level gauge, and weld or rivet the lower support of the fixed guide wire. If the equipment does not have welding conditions, the heavy anchor fixing method can be used to fix the guide wire under the support. For example, the liquid level wave in the container ...

A digital display controller is a simple controller with indication, control, remote transmission and alarm functions. As a secondary instrument commonly used in sensors, it is very important to operate and use it correctly. Applications such as level control, temperature control, pressure control and parameter value display of measured variables. ...

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. RH400 size: 48*96, depth 60, about 250g 1. Thermocouples: K, J, R, S, B, E, N, T, W5RE/W6RE, PL‖, U, L 2. Temperature measurement heat resistance input: PT100, JPT100 3. Tributary voltage: DC0 - DC5V, DC1 - DC5V ...

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. Shortcoming:...

　　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 ...

It is suitable for measuring the level and interface of the liquid medium in the container. In addition to on-site instructions, it can also be equipped with remote transmitters, alarm switches, and detection functions. The indication is novel, the reading is intuitive, eye-catching, and the direction of the observation indicator can be changed according to the user's needs. Large measuring range ...

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 ...

The rkc controller was developed by Japan and is mainly used in plastics and stoves. Of course, it is also widely used in China's industry, there are many people who do not know much about the rkc controller, and some even feel unfamiliar.

1. There is no display of dry-type transformer thermostat Cause of failure: (1) The power supply of the thermostat is not connected; (2) The fuse is blown out. Solution: (1) Turn on the power supply; (2) Replace the fuse. 2. The dry-type transformer thermostat shows that one or three phases are flashing and displays "-OP-" ...

1. To avoid damage to the instrument, pay attention to the correct protection method: in order to ensure the accuracy of the instrument and avoid damage to the instrument, try not to use the protection instrument of isolator or other isolation devices. If you have to do it, you should also pay attention to the careful selection, determine the isolation solution, and wash the isolation film correctly, ...

(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 ...

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, ...
