Bridge Resistance
The bridge resistance of the wheatstone bridge within your sensor.
To find your resistance:
Use a multimeter to determine the resistance across the +Signal and -Signal wires. This value is your bridge resistance. Typical Futek sensors have a bridge resistance of 350, 700 or 1000 Ohms.
Length
Length of engagement. The distance that the two THREADED regions engage. The typical minimum recommended value is 1.5 times the major bolt diameter.
