Is inaccurate force measurement at your mixing plant disrupting production? Xi'an Shenghongchuang provides you with a professional troubleshooting solution for the RSZ-G3 weighing sensor. This manual addresses common issues with weighing sensors in the HJK-304, RSZNC, and other series, providing rapid diagnosis and solutions to help contract executors effectively resolve force measurement deviation problems and ensure production accuracy and efficiency.

I. Core impact of weighing sensor failures on mixing plant production

In the production process of a concrete mixing plant, the force measurement accuracy of weighing sensors such as the RSZ-G3 series is directly related to the accuracy of raw material proportioning. When a measurement deviation of more than 5% occurs, it will lead to quality issues such as substandard concrete strength grades and abnormal slump. According to the requirements of the GB/T 7551-2008 "Load cells" standard, the non-linearity error of industrial-grade sensors under rated load should be ≤0.03%FS, while in actual working conditions, due to factors such as improper installation and environmental interference, models such as RSZQF and RSZ04 may accumulate errors exceeding 0.1%. Based on statistics from 200+ mixing plant cases, Xi'an Shenghongchuang found that 83% of abnormal force measurement issues can be resolved through systematic troubleshooting.

II. Illustrated fault diagnosis process for RSZ-G3 sensors

Step 1: Power supply stability check - Use a multimeter to measure the sensor excitation voltage （recommended value: 10VDC±5%）, voltage fluctuation exceeding ±0.5V will affect the output sensitivity of models such as RSZ-P1 and SHL350.
Step 2: Mechanical structure inspection - Focus on troubleshooting three common installation issues in reaction-kettle mixing plants: ① sensor base level deviation ＞0.5° ② uneven bolt preload ③ insufficient overload protection clearance.
Step 3: Signal output test - Compare the mV/V output value of the RS-HCW sensor under no-load and rated load conditions, and if the non-linearity is ＞0.05%FS, immediate calibration is required.

III. Comparison of maintenance points for different sensor models

Column-type compression sensor：The RSZNC series requires quarterly inspection of the sealing ring condition to prevent slurry ingress from causing abnormal bridge resistance.
Cantilever beam sensor：For the RSZQ model, it is recommended to perform an eccentric load test monthly to ensure that the four-corner error is ＜0.02%FS.
High-temperature environment application：The RSZQF model should be used together with a water-cooling jacket under reaction-kettle operating conditions to keep the working temperature ≤150℃.

IV. Key considerations for contract executors

1. Clarify acceptance standards：The technical agreement should specify the exact indicators of the RSZ-G3 sensor, including: ① creep （30 minutes）≤0.02%FS ② temperature compensation range -10℃~+60℃ ③ IP67 protection rating
2. Spare parts management strategy：It is recommended to stock 10% of sensors of the same model （such as RSZS, HJK-304, etc.） to ensure replacement within 4 hours in case of sudden failure
3. Data traceability requirements：Keep complete calibration records in accordance with the ISO9001 system, including: initial calibration data, periodic verification reports, fault repair logs
