　　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 ...

Programmable logic controllers (PLCs) and temperature controllers (thermostats) offer similar benefits in ensuring effective process control, achieving consistent quality, and minimizing user error in manufacturing. Since the 17th century, process control equipment has been used in a variety of forms.

　High-temperature melt pressure sensors, transmitters, and high-temperature melt pressure gauges are special equipment in extrusion processing. On the production line, melt pressure sensors play an important role in improving melt quality, increasing production safety and protecting production equipment. Use...

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 ...

Floor heating thermostats can be divided into digital thermostats and analog thermostats according to different input and output forms. Digital thermostats generally have liquid crystal display or digital tube display panels, and set and control the temperature through buttons, while analog thermostats generally use knobs or slider band wave wheels to set ...

1. Wiring method 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, The last three legs are connected to ...

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 ...

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. 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. To avoid damage to the instrument, pay attention to the correct protection method: in order to ensure the accuracy of the instrument and avoid damage to the instrument, try not to use the protection instrument of isolator or other isolation devices. If you have to do it, you should also pay attention to the careful selection, determine the isolation solution, and wash the isolation film correctly, ...

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. 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 ...

1. Sudden jump thermostat The type of various sudden thermostats is collectively called KSD, such as KSD301, KSD302, etc., the thermostat is a new type of bimetal thermostat, mainly as a variety of electric heating products with overheat protection, generally connected with the thermal fuse in series, sudden temperature ...

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 leads to the breakpoint of the solder joint, and sometimes it is caused by the phenomenon of virtual soldering at the factory, and the main re-soldering can be done. 2. Temperature controller ...

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 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. ...

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 ...

1. The indicated value is large (or out of range). According to the investigation of our staff, this kind of problem often appears in the atmospheric pressure workshop. When we find that the counterweight of the float in the float level gauge is at a low point, the liquid level must be very high at this time, and the glass plate is inconsistent with the indication of the instrument.

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 ...
