FUTEK offers a variety of miniature donut / thru hole load cells. One of the more popular standard models is the LTH300. It has low profile robust construction available in 17-4 stainless steel with an I.D. range from 1/8" to 3/8" [3.40mm to 9.80mm] and available in capacities from 50 lbs to 1000 lbs. It comes standard with a 10 foot long 29 AWG 4 conductor shield Teflon cable with a very effective mechanical strain relief. The LTH300 has high stiffness due to its low deflection of 0.002" nominal and operating temperature of -60ºF to 200ºF. Some product highlights include:

• Weight: 2 oz
• high selection of standard Inside Diameter in many capacity ranges
• Low deflection
• 17-4 steel construction
• Compression
• Utilizes metal foil strain gauge technology
• Quick delivery
• TEDS option available
• In-line signal conditioned, amplified or digital output available

This product, as well as other LTH models, is typically used to monitor loads in the press or punching, inserting operation. It can be substituted with load washers and pancake load cells if needed. However, donut / thru hold load cells offer a far higher accuracy than load washers but more sensitive to Torque or other extraneous load or moments. Although pancake load cells are slightly more accurate, they are much bigger in size. With FUTEK's constant goal of improvement and design innovations, similar models are constantly being offered with the thinner height while maintaining the large diameters. FUTEK offers a complete turnkey system with related instruments, to interface with PLC or computer or other controllers and can provide full DAQ system with Software in support of automation.
