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. There is no manifestation when the power is on. For this kind of problem, first confirm whether the power supply is there and whether the power supply matches the power supply required by the thermostat, and then check whether the wiring is strong. The problem is still there, then it is the problem of the thermostat itself. 2. There is a manifestation, and the manipulation makes mistakes. The first thing to look at this kind of problem is to look at the control ...

1. The installation of the level gauge must be vertical to ensure that the inner pontoon can move up and down freely in the pipe body. 2. Install a shut-off valve between the container and the liquid level gauge to clean and overhaul the liquid level timing to cut off the material. 3. No magnets are allowed to approach around the main body of the pontoon level gauge, otherwise ...

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 ...

　High-temperature melt pressure sensors, transmitters, and high-temperature melt pressure gauges are special equipment in extrusion processing. On the production line, melt pressure sensors play an important role in improving melt quality, increasing production safety and protecting production equipment. Use...

(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 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: ...

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 ...

Fault 1: The thermostat does not turn on (the screen does not display) Analyze the causes 1. Wrong wiring; 2. The voltage of the input terminal is not enough or the input terminal is damaged by the empty leakage guarantee; 3. Whether the cable between the panel and the power board is broken or plugged incorrectly; 4. Load short circuit or broken ...

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 ...

(1) RH400 size: 48*96, depth 60, about 250g Details: ●A variety of input types are available: 1) Thermocouples: K, J, R, S, B, E, N, T, W5RE/W6RE, PL‖, U, L 2) Temperature measurement RTD input: PT100, JPT100...

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. 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) 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. Power supply and load lines to prevent noise disturbances. 　　3) The power cord of the instrument is generally disturbed 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 ...

1. For thermocouple input, the corresponding compensation wire should be used. 2. For RTD input, 3 wires with low resistance and no difference should be used 3. The input signal line should be far away from the power line of the instrument. Power supply and load lines to avoid noise interference 4. The instrument power cord is usually ...

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.
