OMEGA’s LC900 Series bolt force sensor is a compression load cell designed to measure the clamping force of a bolt. With excellent long term stability and all stainless steel construction, the LC900 Series delivers high reliability in severe industrial environments. This unit is designed to operate by mounting on a flat surface between two mounting washers (included).

The LC901 is also available in metric configurations, with ranges from 0-10,000 to 0-500,000 N. Please see the LCM901 for complete details, or contact our Pressure department for more information.

Rated 3 out of 5 by from 120 Ohm Load Cells The load cells have 120 Ohm resistance. Many of the load cell amplifiers available, including the one recommended for this product, require the load cell to have at least 300 Ohms resistance. That makes this device hard to use.
