Application Use
The LTH300 Through Hole Donut/Washer Load Cell is a miniature, low-profile sensor designed for compression applications requiring the load structure to pass through the sensor such as bolt clamping force measurement.
Design
The LTH300's compact dimensions, light weight, and flexible inner diameter enable seamless integration into space-constrained setups without adding significant bulk to the assembly. The custom full bridge strain gauge and unique monolithic gauge design reduce output errors from extraneous/off-axis loads. Its low power consumption makes it ideal for battery-operated applications or setups where minimizing heat generation is crucial.
A durable 17-4 PH stainless steel construction and operational temperature from -60°F to 200°F (-50°C to 93°C) make it ideal for demanding environments. Its low deflection of 0.001 in (0.025 mm) nominal satisfies applications that require a fast dynamic response. The load cell is RoHS compliant and includes a strain relief cable for enhanced protection and signal integrity.
