RKC Level Gauge – the correct way to use the float level gauge

1. Setup (XMT201-D): Press the SET button for 3 seconds to enter the inner parameter setting state. E: This parameter is the advance of heating stop when P = 0, when P is not equal to 0, the instrument is the intelligent PID working mode, and when P is not equal to 0, the E parameter is meaningless. 2.P: is the proportional band, that is, the proportional ...

　　PT100 RTD is a platinum RTD, which can be regarded as a more commonly used thermometer in the range of medium and low temperatures, and it has a wide range of uses, including medical, electric, industrial production, thermometers and other high-precision thermometers. But due to the range of use ...

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 terminal post of the thermostat is stuck and falls off Cause the compressor not to start, the thermostat dynamic and static contacts can not be disconnected, so that the compressor does not run, the thermostat contacts can not be disconnected, so that the motor of the refrigerator compressor does not stop, in addition to the balance elastic force is too weak, it can also be ...

Wiring Notes: 1. For thermocouple input, the corresponding compensation wire should be used. 2. 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. ...

1. Thermostat contact contact failure Poor contact of the thermostat contacts will cause the compressor to not operate properly. If the contacts are sticky, the compressor will fail without downtime. For this, you can use a small screwdriver to open the metal shell of the thermostat, and then use a fine abrasive cloth to polish the surface of the contacts ...

Take CD901 as an example, L(1) pin to 220 volt live wire, N(2) pin 220 volt neutral wire, 3,4 pins for the first output, 5,6 pins for the second output, 7, 8, 9 pins are alarm output, Finally, the three pins are connected to thermocouples or PT100 ...

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...

The main technical indicators of RKC thermostat · Input: various thermocouple (TC), RTD standard current and voltage signals (see input type table); · basic error: 0.5% of the input full-scale ±±1 word; · Resolution: 1°C, 0.1°C; ...

Measuring principle with hydrostatic pressure: When the level transmitter is placed at a certain depth in the liquid to be measured, the pressure on the welcome surface of the sensor is formulated as: Ρ = ρ .g.H + Po where: P: The pressure on the fluid surface of the transmitter ρ: the density of the liquid to be measured g ...

* 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. ...

How liquid expansion thermostats work Liquid expansion thermostat is a physical phenomenon (volume change) that causes the material (generally liquid) in the temperature sensing part of the thermostat to undergo corresponding thermal expansion and cold contraction when the temperature of the controlled object changes, and the diaphragm box connected with the temperature sensing part expands or ...

Common faults of thermostats 1. There is no display when the power is on. This type of problem first determines whether the power supply is available and whether the power supply matches the power supply required by the thermostat, and then checks whether the wiring is secure. The problem is still there, then it is the problem of the thermostat itself. 2. There is a display, and the control is wrong. This...

1. Prepare the thermostat, wires, and thermal resistance, and print out the wiring diagram of the thermostat 2. Use wire strippers to strip off the wire skin, use crimping pliers, and press the wire end to the cold-pressed terminal. 3. Connect the 220V power supply to the inlet terminal of the thermostat, and connect the thermal resistance to the thermostat ...

1. Set temperature: Press the SET button to set or view the temperature set point. Press the SET button 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, long press the △ key or ▽ key The data will change rapidly, press the SET key again ...

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. 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 ...

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 ...
