Measured Analysis of the Application Performance of PWHE Weighing Sensors in Reactor Stirring Stations

How effective are PWHE weighing sensors in actual applications in reactor stirring stations? As a core technology in the field of flow control equipment, their accuracy and stability directly affect production efficiency. This article provides key decision-making references for technical evaluators through comparative analysis of measured data on the performance of TJH-12, CZL-401 and other series products in high-temperature and high-pressure environments.

1. Core Requirements of Reactor Stirring Stations for Weighing Sensors

In reactor stirring stations in industries such as chemicals and pharmaceuticals, the accuracy of material proportioning is directly related to product quality and process safety. Traditional mechanical weighing devices often encounter the following problems in high-temperature (above 150℃), high-pressure (10MPa+) and corrosive media environments:

• Drift error: Temperature fluctuations cause zero drift of sensors such as the TJH-3 model up to ±0.05%FS/10℃
• Structural deformation: The CZL-401 column-type pressure sensor is prone to creep error under axial force
• Signal interference: Electromagnetic interference generated by the stirring station motor can cause output fluctuation of the LLBHT sensor by ±1.2%

The PWHE series significantly improves reliability under extreme working conditions through an alloy steel sealing structure (IP68) and a temperature compensation algorithm (error <±0.02%FS within the range of -20~200℃).

2. Comparison of Measured Performance of Key Models

Measured data show that under an 80℃ continuous operating environment, the PWHE series has obvious advantages over similar products:

1. Dynamic response: The AC-LC3 model still maintains a response speed of 0.01s under stirring vibration conditions
2. Long-term stability: After 2000 hours of continuous operation, the drift of LZ-GF3 is only 0.03%FS
3. Overload resistance: After a 120% range impact, the accuracy loss of CZL-401 is <0.005%

3. Optimized Solutions Under Special Working Conditions

To address the corrosive media issues in reactor stirring stations, PWHE adopts the following innovative designs:

• Sealing technology: 316L stainless steel welded seal + fluororubber O-ring dual protection
• Signal processing: Built-in ADS1220 chip enables 24-bit ADC conversion, with a signal-to-noise ratio of 110dB
• Installation method: The patented LZ-ZS1 flange structure can eliminate the influence of lateral force

In a strong acid environment test at a pharmaceutical enterprise, the PWHE sensor group (including models such as TJH-3 and LZ-ZS3) operated continuously for 6 months without failure, with data fluctuation controlled within ±0.2kg.

4. Selection Recommendations and Key Points for System Integration

According to the different process requirements of reactor stirring stations, it is recommended that technical evaluators focus on:

During system integration, attention should be paid to: the Profibus-DP communication delay between the weighing module and the PLC should be controlled within 5ms, and calibration should be carried out regularly in accordance with the JJG 539-2016 verification procedure.
