RKC Level Gauges – Precautions for Level Gauges

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. Heating for a period of time, the temperature does not change. Displays the ambient temperature of the site at all times (e.g. room temperature 25°C) In case of such failures, first check whether the SV value setting value is set, whether the instrument OUT indicator is lit, and whether the No. 3 and 4 terminals of the "multimeter" measuring instrument have 12VDC output.

1. Classification of pontoon level gauges The pontoon level gauge is also divided into two types: inner pontoon and outer pontoon, the so-called internal and external division refers to the place where the pontoon is installed, in the container of the liquid to be measured is the inner pontoon, and the outer pontoon is called the outer pontoon outside the liquid container to be measured.

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; The leakage of the thermostat in the temperature sensing chamber causes the contact to fail to operate and lose control ...

1. Take out the room temperature controller, and then connect the power supply terminal of the temperature controller to the power supply according to the terminal diagram of the temperature control chart 2. Then take out the temperature sensor that comes with the temperature controller and detect it 3. According to the temperature controller terminal, the temperature sensor is connected to the controller's transmission.

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

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.

How it works The sudden jump thermostat is a kind of bimetal disc after constant temperature as a heat-sensitive reaction component, when the temperature of the main part of the product increases or decreases, the heat generated is transferred to the bimetal disc, and when the operating temperature is set, it acts quickly, and the contact is broken through the action of the mechanism.

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) After 6 months to 1 year of operation, the sensor should be visually inspected and routinely calibrated. (2) Regularly check whether the sensor is bent and deformed by external force to avoid ball jamming. (3) Regularly check whether the magnetic induction switch element of the sensor is aging and failing, ...

Thermostat, according to the temperature change of the working environment, physical deformation occurs inside the switch, so as to produce some special effects, a series of automatic control elements that produce on-on or off-action actions, or different principles of electronic components at different temperatures and working states to give ...

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 ...

　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. Heating for a period of time, the temperature does not change. The ambient temperature of the site (e.g. room temperature 25°C) is displayed at all times. In case of such failures, first check whether the SV value setting value is set, whether the 0UT indicator light of the meter is lit, and whether the No. 3 and No. 4 terminals of the meter with the "multimeter" are 12VD ...

1. The temperature setting is set by the knob, which is convenient and intuitive 2. It can be directly installed on the standard junction box on the wall. 3. Beautiful appearance and reliable performance. 4. The switch adopts toggle type, which feels comfortable and has a long life. 5. It can control two-wire or three-wire electric (ball...

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 ...

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 ...

1. Wall installation, the height is about 1.2 meters, generally on the same horizontal line as the electric lighting switch of the home. 2. Installed on a wall where the surrounding air flows freely, and is not affected by other heat sources (e.g. sunlight), air flow from doors and windows, or external wall temperature, etc. 3. Advance ...

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) Before use, first check whether the level gauge is within the verification cycle, otherwise, it should be calibrated, and replaced in time if it is unqualified. (2) The sensor should be installed horizontally, and the length of the lower entry should meet the technical requirements. (3) The connection between the sensor and the explosion-proof junction box should be tightened and tightened.
