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 ...

Many household appliances and large-scale equipment products will be installed in the use of thermostats, thermostats will be combined with the change of ambient temperature in the switch when working physical deformation, which will produce some special effects, resulting in conduction or disconnection action, in order to achieve automatic ...

(1) Size selection When replacing the thermostat, choose according to the original size; The newly added thermostat should take into account the overall coordination of the cabinet installed, too large to fit, too small to see the display, the same function of the thermostat, the price of large volume will be more expensive, small size may function expansion...

There are many types of instrumentation and have a wide range of applications in many fields. Because of this, there are many problems with the failure of instruments in the process of use, so it is necessary to pay more attention to the repair and maintenance of instruments and meters, which can effectively improve the performance of instruments and meters, and can extend the performance of instruments and meters.

1. The specific gravity of the liquid to be measured must be greater than the specific gravity of the float 2. The measured medium should not contain ferromagnetic impurities 3. The float level gauge should be installed in an unobstructed position when the float moves up and down 4. Magnets are not allowed to be close around the float level gauge, otherwise it will affect the float.

1. Grounding method: It is connected to the grounding metal parts of the equipment through the metal cover of the thermostat. 2. The thermostat should work in the general indoor environment where the relative humidity of the air is not more than 90%, and there are no corrosive gases, flammable gases and conductive dust. 3. The thermostat adopts contact ...

CH102 (48×48×100mm) CH402 (48×96×100mm) CH902 (96×96×100mm) 1. RH400 size: 48*96, depth 60, about 250g 1. Thermocouples: K, J, R, S, B, E, N, T, W5RE/W6RE, PL‖, U, L ...

1. Set temperature: Press the SET button to set or view the temperature set point. Press the SET key digital tube character start flashing, indicating that the appearance has entered the setting state, press the △ key to increase the set value, press the ▽ key to decrease the set value, press and hold the △ key or ▽ key The data will change rapidly, press the SET key again The appearance will return ...

(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.

1. Electrical parameters: (1) VDE, CQC, UL, TüVAC250V 50-60Hz 10A (resistive load) (2) ULAC125V 50Hz 15A (resistive load) 2. Operating temperature range: -50-270°C (optional), temperature accuracy: ≥ ±2°C 3. Reset and action ...

1. Do not wipe with acidic, alkaline and other corrosive liquids and water-containing rags when cleaning, so as not to damage the temperature controller and affect its normal use. 2. Do not decorate and cover the temperature controller. The thermostat has a built-in temperature sensor to sense the outside temperature. Therefore, Wen ...

1. The cleanliness and finish of the contact surface have a great impact on the working state of the contact. When the appearance of the contact is rough or there is residue 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 the residues; Add the process of residue selection, ...

1) Separate households are independently heated, and floor heating is installed in small households, and boiler temperature control is applicable. 2) Separate households independent heating duplex building installation floor heating room temperature control. 3) Separate households for independent heating, large duplex villas are suitable for floor heating stratified temperature control. ...

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-" ...

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. 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, ...)

In temperature measurement, thermocouples and RTDs are both contact temperature measurements, and although they both measure the temperature of an object, their principles and characteristics are different. This article first introduces thermocouples, which are widely used in temperature measurement temperature control devices.

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 ...
