Spec Sheet
 
Description

Model LTH300 is a Donut Load Cell built for Press, or Inline compression applications. The standard LTH300 Donut 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 option for external matched output readily available.

 

Donut Load Cells

FUTEK's Donut Load Cells (LTH Series) offer high accuracy and high stiffness. 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, bolt force measurements (bolt loading), clamping forces, overload monitoring post or leg mount, and rolling mill systems. Measurement range for begins at at 5 lb and goes up to 50,000 lbs. Standard sensor output is mV/V. Amplified output available via in-line amplifiers, such as FUTEK Signal Conditioners.
