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.
Its custom full-bridge strain gauge and unique monolithic gauge design reduce output errors caused by extraneous or off-axis loads, providing more accurate and repeatable measurements.
Its low power consumption makes it ideal for battery-operated applications or systems where minimizing heat generation is essential.
Constructed from durable 17-4 PH stainless steel, the LTH300 operates over a temperature range of -60°F to 200°F (-50°C to 93°C), making it suitable for demanding industrial environments.
Its nominal deflection of only 0.001 in (0.025 mm) provides a fast dynamic response for high-speed measurement applications.
The load cell is RoHS compliant and incorporates a cable strain relief for enhanced mechanical protection and signal integrity.
Calibration and Customization
FUTEK's ISO-certified calibration laboratory offers multiple calibration options to ensure precision, reliability, and compatibility with a wide variety of instrumentation.
For specialized applications, FUTEK can develop custom versions designed to operate in environments such as:
- Extreme temperatures.
- Radiation environments.
- Vacuum or low-outgassing applications.
- High vibration or shock environments.
A customized version of the LTH sensor family was integrated into NASA's Curiosity Mars rover. Manufactured by FUTEK in 2008, it continues to provide accurate drilling force measurements under the extreme conditions of the Martian environment.
