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. 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 ...

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 ...

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 ...

1. The temperature controller control method is generally divided into two types: One is controlled by the temperature change of the cooled object, and the vapor pressure temperature controller is mostly used, and the other is controlled by the temperature difference change of the cooled object, and the electronic temperature controller is mostly used. ...

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, ...

　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. 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.

When transporting and unpacking, it is necessary to avoid excessive shock and vibration; The installation should be firm and reliable, and the pontoon should be installed vertically to prevent the pontoon from colliding with the interior wall of the pontoon; When the pontoon is hooked, it should not swing or pull and compress sharply, so as not to damage the sensor and reduce the accuracy of the instrument; ...

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 *** ...

The first output method is relay output, which is output for temperature control through the switching signal of the relay on/off, which is used to directly control the load less than 5A, or directly control the contactor and the intermediate relay, and control the high-power load externally through the contactor. The second ...

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. There is no liquid level display or lower liquid level display When the sewage is discharged, only a small amount of condensate flows out, and it is judged that the pontoon is blocked. Treatment: Dismantle the outer pontoon and find that the pontoon is almost filled with dirt and impurities. Clean, calibrate, and return to normal. 2. The liquid level display is ...

Principle of electronic thermostat: The electronic temperature controller (resistive type) is measured by the method of resistance temperature sensing, and generally uses platinum wire, copper wire, tungsten wire and semiconductor (thermistor, etc.) as the temperature measurement resistor, which has its own advantages and disadvantages. Household Air Conditioner Temperature Controller ...

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 ...

In general, the following points should be followed when installing a float level timer: 1. In order to prevent the float from sliding or hitting the sealed tube at high speed during transportation, causing the measuring belt to fall out, the instrument is fixed at the bottom of the sealed tube with a clamp before leaving the factory, and the magnet is on the top of the sealed tube.

1. The installation of the level gauge must be vertical to ensure that the inner pontoon can move up and down freely in the pipe body. 2. Install a shut-off valve between the container and the liquid level gauge to clean and overhaul the liquid level timing to cut off the material. 3. No magnets are allowed to approach around the main body of the pontoon level gauge, otherwise ...

(1) For the indicator, also known as the display panel, the indicator plays the role of local display, convenient for long-distance observation of the actual situation of the liquid level, the indicator is generally bundled with the pontoon, easy to install. (2) It is a magnetic float, which is located in the pontoon and is in direct contact with the liquid to be measured, ...
