Specifications and models of RKC thermostats

Thermocouples, RTDs, analog and other signals are freely inputted, and the range can be set freely; The software zeros 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; Fuzzy theory combined with traditional PD method, fast and stable control, advanced tuning ...

(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, ...

The reasons why the temperature control table shows HHH are as follows: 1. The thermocouple signal line is reversed, or short. 2. If the temperature control meter is in normal use before, it is recommended to check whether the signal line of the thermocouple is broken. 3. The wire inside the thermocouple is broken. 4 ...

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.

1) For RTD input, 3 wires with low resistance and no difference should be used. 2) The input signal line should be far away from the power line of the instrument, the power supply line and the load line to avoid noise and annoyance. 3) The power cord of the instrument is generally annoyed by the power supply. 4) Instrument complement ...

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 ...

Master the common problems of several common intelligent temperature controllers, and solve them by yourself when you encounter problems, and you don't need to spend time and effort to find someone to repair, the common problems are as follows: 1. Heating for a period of time, the temperature does not change. Ambient temperature (e.g., room temperature 25°C) is displayed at all times ...

1. The special integrated instrument chip has more reliable anti-interference and stability. 2. Signal input, ordinary heat signal can be connected through menu settings. 3. You can modify the display range, transmission output range, alarm value and online report J mode. 4. Soft ...

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.

* Alarm table {ALM1} (standard built-in) A: Upper limit deviation alarm G: Standby upper and lower limit deviation alarm attached B: Lower limit deviation alarm H: Upper limit input value alarm C: Upper and lower limit deviation alarm J: Lower limit input value alarm D: Alarm in the range K: Attached standby ...

The instrument can be cleaned only after the power is off; To remove stains from the monitor, use a soft cloth or cotton paper; The display is easy to be scratched, and it is forbidden to use hard objects to operate the panel buttons, otherwise the keys will be damaged or scratched. ...

Principle of electronic thermostat: The electronic temperature controller (resistive type) is measured by the method of resistance temperature sensing, and generally uses platinum wire, copper wire, tungsten wire and semiconductor (thermistor, etc.) as the temperature measurement resistor, which has its own advantages and disadvantages. Household Air Conditioner Temperature Controller ...

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 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 ...

1. First of all, determine the set temperature of the thermostat and make sure that it is the same as the temperature you need. 2. Recognize the operating form of the thermostat, usually there are two forms of cooling and heating, and choose the corresponding form according to the demand. 3. Acknowledging the operating condition of the thermostat, usually with active ...

1. Set temperature: Press the SET button to set or view the temperature set point. Press the SET key digital tube characters to start flashing, indicating that the instrument 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 ...

fold When the RKC thermostat comes out, it is a single-loop regulator, that is, it only has a heating function, which is called the basic meter, which is generally sent to the agent, and the agent will expand the multi-channel adjustment and alarm output control function, which is called "changing the meter" in the industry, so as to ensure that there is very little hardware cost.

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. 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 ...

Press the SET button to set or view the temperature set point, press the SET key digital tube characters to start flashing, indicating that the instrument 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 instrument returns to normal working condition ...
