As a precision force measurement device, abnormal readings from push-pull gauges can directly impact measurement reliability. According to industrial field statistics, 90% of measurement anomalies can be attributed to the following four main causes:
Sensor Malfunction: Prolonged overload use can lead to decreased sensor sensitivity, manifesting as measurement drift or degraded linearity. Regular full-scale calibration is recommended, and impact loads exceeding 150% of rated capacity should be avoided.
Mechanical Component Wear: Wear in guide mechanisms can reduce measurement repeatability, causing irregular data fluctuations. Regularly inspect sliding component clearances, maintain proper lubrication, and replace worn parts when necessary.
Environmental Interference: Temperature fluctuations (exceeding ±5°C) and electromagnetic interference can significantly affect measurement stability. The equipment should be placed in a constant-temperature environment, kept away from strong electromagnetic fields, and shielded when required.
Improper Operation: Non-standard clamping methods (such as eccentric loading) can increase measurement errors. Ensure the force axis aligns with the sensor centerline during operation, with deviation not exceeding 0.5°.
Preventive Recommendations: Establish a daily inspection system including zero-point checks, repeatability tests, and environmental monitoring; conduct professional calibration quarterly; confirm equipment status before critical measurements. Standardized usage and regular maintenance can ensure continuous and stable operation of push-pull gauges.
