Description

Application Use

The LTH150 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

Its compact dimensions, light weight, and 0.14" [3.5 mm] 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.

LTH150’s 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 0.0005 in (0.013 mm) nominal satisfies applications that require a fast dynamic response. The load cell is RoHS compliant and includes a #34 Gauge Braided Shielded cable for enhanced protection and signal integrity.
