RKC Level Gauge – The correct maintenance method for float level gauges

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 ...

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.

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. Bellows or diaphragm air conditioner thermostat 1. Fault phenomenon: poor contact or burning, resulting in the circuit can not be connected; The frequent action of the contact arc and sticking causes the circuit to be unbreakable; The thermostat in the temperature sensing chamber leaks, causing the contact to fail to operate and lose control. ...

1. Confirm the angle sample first. See where the angle of the sample is today. 2. Pick up the thermostat, first confirm whether the switch of the thermostat is tight, stuck, whether the white dot falls off, whether there is sound when the thermostat contacts are in contact, and if there is no sound, there should be two possibilities! ...

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 ...

　　The power indicator is normal, but the temperature control meter has no on-screen display. This kind of fault is mostly caused by the heating of the voltage regulator element (7805 or 7812) of the temperature controller during long-term use, resulting in a break point in the solder joint, and sometimes a virtual soldering occurs at the factory, resulting in re-soldering. ...

(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. The cleanliness and finish of the contact surface have a great impact on the working condition of the contact. When the surface of the contact is rough or there is excess material on the contact, it is easy to cause arcing and reduce the life of the contact. Therefore, the parts cleaning process should be improved to eliminate excess materials; Increasing the process of screening excess materials, ...

(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.

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, ...

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 ...

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.

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 dry-type transformer thermostat does not appear 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 shining and showing "-OP-" ...

1. After heating for a period of time, it is found that the temperature has not changed, and the temperature has been displayed at the time of the ambient temperature. In this case, you need to check that the SV value setting value is set, whether the OUT value indicator of the meter is not lit, and whether the No. 3 and 4 segments of the universal meter are 12VD ...

The correct selection of the level gauge can ensure the better use of the level gauge. What kind of level gauge should be selected according to the physical and chemical properties of the fluid medium to be measured? What is the diameter of the level gauge, the flow range, the lining material, the electrode material, and the output current? can adapt to the ...

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 ...

1. Set temperature: press and hold the SET key, at this time the tube character begins to flash, proving that the instrument has entered the set state, increase the up button, decrease the down button, and press and hold the up and down buttons to quickly change, when the desired temperature is reached, then press the SET button The instrument is set. 2. Return control: press SET ...

Mechanical thermostat mainly refers to a temperature control method that adjusts refrigeration by rotating the button, with an expanding thermostat, which will automatically expand and contract according to the change of temperature, so as to control the power supply, the most primitive type, and the structure is relatively simple. Advantages of mechanical thermostats: ...
