Precautions for Installation and Use of Tension Sensors
Handle tension sensors with care, especially small-capacity models using aluminum alloy as the elastic body. Any impact from vibration or dropping may cause significant output errors.
When designing and installing the loading device, ensure the load force line aligns with the sensor’s force axis to minimize the impact of inclined or eccentric loads.
For level adjustment:
If using a single sensor, adjust its base mounting surface to level with a spirit level.
If using multiple sensors simultaneously, keep their base mounting surfaces as level as possible to ensure each sensor bears roughly equal force.
Select the sensor’s rated load according to the specified range in its manual.
The sensor’s base mounting surface should be as flat and clean as possible (free of oil, film, etc.). The mounting base itself should have sufficient strength and rigidity (usually higher than the sensor’s own strength and rigidity).
The sensor’s housing, protective cover, and wire joints are sealed—do not open them.
To prevent chemical corrosion, apply petroleum jelly to the sensor’s surface during installation. Avoid using it in scenarios with direct sunlight or sudden temperature changes.
If such conditions are unavoidable, install protective or mitigation devices.
To prevent damage from large currents passing through the sensor, do not perform welding operations after sensor installation. If necessary:
Add a copper braided wire bypass at both ends of the sensor’s loading device.
Do not extend the cable arbitrarily. If extension is necessary, solder the joints and apply moisture-proof sealant.
Cover the sensor with baffles or a protective to prevent debris from entering its moving parts (which could reduce measurement accuracy).
Keep the sensor cable away from high-power power lines or pulse wave areas. If unavoidable, route the cable through a separate iron pipe and minimize the connection distance.
Select the sensor’s rated load per its specified range. Though the sensor has some overload capacity, avoid overloading (even short-term overload may cause permanent damage).
For high-precision applications, preheat the sensor and supporting instruments for 30 minutes before use.
Store the sensor in a dry, ventilated room free of corrosive gases.
