Platinum thermal resistor temperature sensor WZPM2-08-102.5-M18-S is widely used in the industrial field for monitoring and controlling temperature fields. Its technical characteristics and design parameters make it a reliable choice in a variety of scenarios. In view of the representative measurement requirements of the temperature field of large-diameter steam pipelines, a comprehensive evaluation is required from the core performance, installation adaptability, environmental compatibility and data reliability of the sensor to determine whether it can meet the technical requirements in actual applications. The following is a discussion on technical parameter analysis, application scenario adaptability, potential challenges and optimization suggestions.

1. Analysis of technical parameters and design characteristics

Platinum thermal resistance WZPM2-08-102.5-M18-S is suitable for installation requirements of medium to large diameter pipes. The thermal response time of the sensor is τ0.5≤45 seconds, which means that when the fluid flow rate is 0.4m/s, the response to a 50% step temperature change can be completed within 45 seconds. This feature has a certain timeliness in a dynamic temperature environment. In addition, the maximum current of 1mA and the three-wire design allowable to pass through effectively reduce the influence of lead resistance on measurement accuracy and improve the stability of signal transmission.

In the high temperature and high pressure environment of steam pipelines, the pressure resistance and temperature upper limit of the sensor are key considerations. The DN300 steam pipeline usually operates at a pressure of several MPa, and the 6MPa nominal pressure of the temperature sensor WZPM2-08-102.5-M18-S can cover the requirements of conventional working conditions. However, it is necessary to pay attention to whether the steam temperature exceeds the upper limit of 350℃. If the actual temperature of the pipeline is close to or exceeds this threshold, the long-term stability of the sensor may face challenges.

2. Installation adaptability and measurement representativeness

For large-diameter pipelines of DN300, the installation position and probe depth of the temperature sensor WZPM2-08-102.5-M18-S directly affect the representativeness of the temperature field measurement. The temperature distribution of the steam pipeline is usually axially symmetrical, but factors such as flow rate, pressure and pipeline insulation layer may cause local temperature differences. According to the principles of fluid mechanics, the probe of the temperature sensor needs to penetrate the pipeline to a sufficient depth to avoid interference with the measurement results caused by heat dissipation on the wall or local flow velocity changes.

The high temperature, high pressure and humid environment of the steam pipeline place strict requirements on the material durability of the sensor. The platinum thermal resistance WZPM2-08-102.5-M18-S uses imported platinum resistance elements, and its long-term stability R0 drift at high temperature is ≤0.04%, indicating that its performance attenuation is controllable.

In long-term operation, the reliability of the lead connection and sealing interface of the thermal resistor sensor is also critical. The installation space of the DN300 pipeline may be relatively compact, and the temperature resistance and tensile strength of the high-temperature wire need to match the pipeline environment. If the sensor cable is exposed to the steam environment, it is recommended to use armored or high-temperature insulating materials to extend the service life. At the same time, regular calibration and maintenance are the basis for ensuring measurement accuracy, and a reasonable maintenance cycle needs to be formulated in combination with the working conditions.

In temperature field monitoring, the measurement results of a single temperature sensor need to be analyzed in conjunction with other parameters (such as pressure and flow) to form a complete working condition map. WZPM2-08-102.5-M18-S supports multiple output modes such as resistance value, 4-20mA or 0-5V, and can be flexibly connected to DCS or PLC systems. However, although the three-wire wiring method can reduce the interference of lead resistance, the signal attenuation problem still needs to be paid attention to in long-distance transmission. If there is electromagnetic interference in the pipeline system, the signal anti-interference ability needs to be improved through shielded wires or isolation modules.

3. Potential challenges and optimization suggestions

Although the temperature sensor WZPM2-08-102.5-M18-S has many adaptability advantages, the following issues still need to be paid attention to in the actual application of DN300 steam pipelines:

Insufficient probe depth: It is recommended to customize a longer probe according to the pipeline diameter, or adopt a multi-point array layout to ensure that the measurement points cover the core area.

Upper temperature limit: If the pipeline temperature exceeds 350℃, it is necessary to evaluate the high-temperature model or use a thermocouple sensor alternative.

Vibration and corrosion protection: Install a shock-absorbing bracket in the high-vibration area, and select a corrosion-resistant probe material or protective sleeve.

System integration optimization: Strengthen signal anti-interference design, regular calibration and maintenance to ensure long-term stability.

Overall, the platinum thermal resistance temperature sensor WZPM2-08-102.5-M18-S has the basic ability to adapt to the temperature field measurement of DN300 steam pipelines in terms of technical parameters and design characteristics, especially in terms of pressure tolerance, accuracy level and signal output mode. However, its insertion depth and upper temperature limit may become potential constraints, and adaptability adjustments need to be made in combination with specific working conditions. By reasonably optimizing the installation plan, strengthening environmental protection measures and improving the system integration design, the sensor can effectively meet the temperature monitoring needs of large-diameter steam pipelines and provide reliable data support for industrial process control.
