LTH Series is a Donut Load Cell (aka Thru Hole load Cell) is a variation of a low profile compression load cell and features a compact, smooth thru-hole design for use in applications which require the load structure to pass thru the sensor.
Typical applications include press, Inline compression applications, bolt force measurements (bolt loading), clamping forces, overload monitoring post or leg mount, and rolling mill systems.

Offered in either tension or tension / compression models, measuring load ranges from 5lb to 50,000 lbs. The standard sensor output is mV/V. Amplified output available via in-line amplifiers, such as FUTEK Signal Conditioners (link).
The standard LTH Through Hole Load Cell model has a very robust construction available in 17-4 Stainless Steel, with an I.D. range of 1/8” to 3/8” and a 10 feet long 29 AWG 4 conductor shielded Teflon cable. You will also find Thru-Hole Load Cell and donut load cells for external matched output readily available.
