Compression Load Washer Load Cells-Series MIN845

DESCRIPTION

A US Manufacturer of: Pressure, Temperature, Load/ Force/Torque, and Displacement Sensors. ISO 9001/AS9100 Certified The Series MIN845 compression load cells are low profile load washers. The miniature thru-hole configurations are often use for measuring tension on fasteners. Constructed of stainless steel, these bonded foil strain gage force sensors are available in a wide selection of both standard and special outside diameters and inside diameters. For best results, MIN845 load cells are recommended to be used with a set of top and bottom hardened washers and/or spherical washer sets to ensure even loading and to protect the load cell from fastener inconsistencies. These mv/v output load washers can be used with Stellar Technology’s selection of inline and DIN rail mount signal conditioners to provide current or voltage outputs. Each unit is shipped with a 5 point calibration record traceable to NIST as standard.
