RKC Level Gauge – How the level gauge works

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 scale of the operating temperature, the required accuracy, the atmosphere of the application, the performance of the measurement target, the response time and the economic benefits. 1. Selection of measurement accuracy and temperature measurement scale 1) The operating temperature is 1300-1800 °C, and the accuracy is required to be more accurate than ...

1. There is no liquid level display or lower liquid level display When the sewage is discharged, only a small amount of condensate flows out, and it is judged that the pontoon is blocked. Treatment: Dismantle the outer pontoon and find that the pontoon is almost filled with dirt and impurities. Clean, calibrate, and return to normal. 2. The liquid level display is ...

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 ...

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 ...

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. The buoy level gauge is welded and installed under the guide wire At the bottom of the container, determine the position according to the requirements of the movement direction of the level gauge buoy, and weld or rivet the support under the fixed guide wire. 2. Buoy level gauge ruler installation 1. The connecting part of the ruler should be flat.

　　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 ...

Fault 1, the indication is abnormal The float level gauge is not indicated properly and is a very common fault of the float level gauge. Usually there are the following manifestations: Phenomenon 1: The float level gauge in the atmospheric pressure workshop has the largest indication. Troubleshooting: The float was found to be ...

In most cases, in Europe, the thermostat is a necessary accessory for the wall-hung boiler, and the two are delivered to the user at the same time, and most of the thermostats equipped are intelligent thermostats. In China, nearly 95% of the wall-hung boilers that have been installed in operation and are being installed and debugged and ready to be put into use are not equipped in advance.

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.

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.

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 ...

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 ...

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. Used to control fan coil unit, electric valve, damper and other equipment; 2. The switch adopts toggle type, which feels comfortable and has a long life; 3. Set the temperature by twisting (the temperature range can be limited); 4. The thermostat can be installed directly on the wall or on the standard junction box; ...

The working principle of dry-type transformer thermostats The dry-type transformer temperature controller is a new generation of controller designed for the safe operation of dry-type transformers. The controller adopts single-chip microcomputer technology, and uses three platinum thermal resistors embedded in the three-phase winding of the dry-type transformer to detect and display the transformer.

1. The level gauge is adjusted normally, and it is found that the float is "absorbed" for a period of time in a certain position after it is put into use. This is mainly caused by the level gauge passing through the steel platform device and being spaced too close to the steel plate. Therefore, it is necessary to pay special attention to the level gauge to connect the pipe wall with the steel platform device.

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, ...

Motors are divided into two categories: DC motors and AC motors, and AC motors are divided into asynchronous motors and synchronous motors, and their respective speed regulation principles are also different. According to the speed regulation requirements of the motor, it can be divided into two categories: DC power converter and AC power converter: ...
