1. Select the appropriate level gauge First of all, it is necessary to choose the appropriate level gauge. The following factors should be taken into account in the selection of a level gauge: Measure the properties of the medium: e.g., temperature, pressure, viscosity, corrosiveness, etc. Measuring range: i.e. the height range of the liquid ...

(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...

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, the power supply line and the load line to avoid noise and annoyance. 3) The power cord of the instrument is generally annoyed by the power supply. 4) Instrument complement ...

The reasons why the temperature control table shows HHH are as follows: 1. The thermocouple signal line is reversed, or short. 2. If the temperature control meter is in normal use before, it is recommended to check whether the signal line of the thermocouple is broken. 3. The wire inside the thermocouple is broken. 4 ...

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 ...

Fault 1: The thermostat does not turn on (does not light up) Analyze the causes 1. Wrong wiring 2. The voltage of the input terminal is not enough or the input terminal is damaged by empty opening and leakage 3. Whether the cable between the panel and the power board is broken or plugged incorrectly 4. Load short circuit or open circuit, probe ...

Faulting and troubleshooting of vapor pressure temperature controllers (1) Common faults and common faults of the vapor pressure type temperature controller include contact burning or adhesion, failure of the mechanical transmission mechanism and leakage of temperature sensor in the temperature sensing tube. Its detection method is: put the thermostat knob in a parking position, and use ...

In winter, the surface of the power plant's measuring instruments is frozen and condensed, which can lead to poisoning, fire and even explosion. Therefore, the cold and freeze protection of the appearance of the instrument is particularly important. First, the selection method (1) Choose the appearance with insulation device. According to the category of appearance ...

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 ...

Wiring Warning: If the instrument fails or an error occurs, which can cause a system failure, an external protection circuit is installed to prevent such accidents: In order to prevent damage or failure of the instrument, choose an appropriate fuse to protect the power cord and input and output lines from strong power shocks. Power supply ...

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.

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. 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 ...

* 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 ...

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.

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 ...
