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 ...

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 ...

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 ...

1. The temperature setting is set by the knob, which is convenient and intuitive 2. It can be directly installed on the standard junction box on the wall. 3. Beautiful appearance and reliable performance. 4. The switch adopts toggle type, which feels comfortable and has a long life. 5. It can control two-wire or three-wire electric (ball...

CH and CD series intelligent temperature controller is a multi-functional adjustment instrument with special microprocessing, which adopts switching power supply and surface mount technology (SMT), so the instrument is delicate and compact, and the performance is reliable. The unique self-diagnosis function, self-tuning function and intelligent control function make it possible for the operator to pass the ...

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 ...

1. The three wiring methods of Pt100 RTD are different in principle: The two-wire system and the three-wire system are measured by the bridge method, and the relationship between the temperature value and the analog output value is given after ***. There is no bridge on the four wires, it is completely just sent with a constant current source, measured by a voltmeter, and the test is given after *** ...

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 causes the solder joint to show a breakpoint, and sometimes it is caused by the phenomenon of virtual soldering at the factory. 2. Temperature controller ...

(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. 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.

The core control algorithm of the thermostat is PID control, P (Proportional) + I (Integral) integral + D (Differential) differential control. In addition to the traditional PID control algorithm, RKC also has ON-OFF control, self-tuning parameter control, adaptive parameter control and other algorithms, temperature control ...

First, the selection of the orientation of the thermostat device 1. Easy to operate locally; 2. It can include the average temperature of the local area; 3. Localities with more human activities; 4. It can avoid cold and heat sources; That is to say, the orientation of the device should be far away from radiators, away from doors and windows...

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...

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, ...

　　Analog-to-digital converters The analog-to-digital converter comprises a first transmission circuit, which receives an input voltage and an output clock signal, which is phase-shifted, depending on the input voltage, and a second transmission circuit receives a reference voltage and an input clock signal, and outputs a reference clock signal, which ...

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, ...)

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 ...

1. Power conversion: convert the voltage (rated 100V) and current (rated 5A or 1A) of the transformer into voltage (several volts) to meet the requirements of weak current components. 2. Isolation: current, secondary side security, and work grounding are used to ensure the safety of people and equipment, while weak current ...
