Starrett BLC-10, 10 lbF S-Beam Sensor for L1 System; 10 lbF / 160 ozF / 50 N / 5 kgF / 5000 gF; M6 Thread. These sensors are used exclusively with Starrett L1 Force Systems. Starrett BLC load cell sensors are full-bridge, temperature compensated, strain gage instruments designed and optimized for basic force testing applications. These S-beam sensors feature high axial stiffness and minimal deflection at full capacity which leads to improved measurement accuracy. The BLC sensors are general purpose sensors available in capacities from 2lbf to 500lbf (10 to 2500N).
