WZPK-436S armored platinum resistor

Explosion proof armored thermistor is a temperature sensor widely used in industrial automation systems. Through temperature sensors, the temperature parameters of the controlled object can be converted into electrical signals, which are transmitted to display, record, and regulate instruments to detect, adjust, and control the system.

In chemical plants and production sites, various explosive and flammable chemical gases and vapors are often present. Using ordinary platinum resistors is very unsafe and can easily cause environmental gas explosions. Therefore, explosion-proof thermal resistors must be used as temperature sensors in these situations. The explosion-proof platinum resistor products produced by our factory are suitable for use in places with explosive gas hazards within the temperature range of dIIBT4 to dIICT6.

The explosion-proof thermistor produced by our factory adopts imported components as temperature sensing elements, and its technical performance meets the technical requirements and division table of JB/T8622-1997 Industrial Platinum Electrotechnical Conditions. At the same time, the general requirements for explosion-proof electrical equipment GB33836.1-2000 and GB3825.2-2000 are used for product compliance. The explosion-proof inspection station for instruments and meters shall conduct specialized review and approval of the product's drawings, technical documents, and prototypes, and issue explosion-proof certificates.

Nominal pressure

Generally refers to the static external pressure that the protective tube can withstand without breaking at room temperature, and the test pressure is generally 1.5 times the nominal pressure. In fact, the allowable nominal pressure is not only related to the material, diameter, and wall thickness of the protective tube, but also to its structural form, installation, insertion depth, flow velocity of the measured medium, and various other factors.

Thermal resistance insulation resistance

The test voltage for insulation resistance at room temperature can be taken as 10-100V. The temperature should be within the range of 15-35 ℃, and the relative humidity should not exceed 80%. The insulation resistance value at room temperature should not be less than 100M Ω.

Thermal resistance allows current to pass through

The current measured through a platinum resistor should not exceed 5mA

Explosion proof type and level

Explosion proof level: dIIBT4 or dIICT4; DIIBT6 or dIICT6

Shell protection level: IP65

Instruments must be calibrated and calibrated before use. Instruments that are used for a long time should also be regularly calibrated, and their cycle should depend on the degree of use and emphasis. When the instrument is equipped with long-distance transmission and secondary instruments, it should be calibrated and calibrated together with the secondary instruments.

7. Stainless steel pressure gauges should be equipped with barrier devices and buffering devices when measuring media with high viscosity and fluctuating pressure.

4. After setting and connecting the electrical circuit of the pressure gauge (refer to the schematic diagram), carefully inspect and test it.

The evaluation of custodial data intermediaries must be conducted from time to time to attract investors to complete the level of development. "In the future, investors with divergent and unfavorable views are stopping evaluating custodial data intermediaries. The theme of this lecture is" Attracting Investors: What Common Knowledge Do Custodian Data Intermediaries Need to Know ", and will focus on key topics such as financial evaluation, customers, trade plans, competitive positioning, future plans and strategies.

Stainless steel pressure gauges are widely used in industries such as petroleum, chemical, synthetic fiber, metallurgy, power plants, and food to measure the pressure of various fluid media in processes that require high corrosion and high temperature resistance

6) Short circuit breaking talent (Ics) for operation: 6A-40A: 6000A, 50A-63A: 4500A. 7) Number of poles: a. Monopole (1P); b. Bipolar (2P); c. Three poles (); d. Quadrupole (4P). Schneider miniature circuit breaker 8), instantaneous trip type: a. C type (5ln-10ln); b. D-type (10ln-16ln).

The concave convex hollow vertical reinforcement structure of the water guiding and drainage waterproof and drainage protection board can quickly and effectively discharge rainwater, and even eliminate the static water pressure of the waterproof layer. Through this type of water guiding principle, the consequences of waterproofing can be achieved. Waterproof function: Poly (HDPE) polystyrene (PVC) waterproof and drainage protection board material itself is a good waterproof material.

The transformation and upgrading investment in the manufacturing industry is rapid. From January to May, the reform investment was 15.6%, with a growth rate 10.4 percentage points higher than the manufacturing investment; The proportion of homework investment accounted for 45.4%, which is 4.1 percentage points higher than the same period last year. 2. Since previous years, the investment growth rate has continued to be higher than the total investment from January to May, with an investment rate of 8.1%, which is 1.3 percentage points higher than the same period last year; The proportion of investment to total investment is 59.3%, which is 1.1 percentage points higher than the same period last year; The contribution rate to investment is 78%.

The independent laboratory relies on rapid development to handle the consequences of instrument costs, which brings a small amount of diagnostic demand. However, the equipment required for diagnosis is expensive, and there is also a need for responsive personnel on a daily basis. This is a significant cost for any field, which inevitably limits the application of diagnosis. After nearly 10 years of development, the independent medical laboratory has begun to take shape, including Di'an Diagnosis, Jinyu Medicine, and other independent medical laboratories, which have undergone a rapid expansion stage.
