Bestech Australia presents the M-2230 thread friction sensor, from Lorenz. This sensor measures the pre load, friction torque underneath the screw head and thread friction torque.
The thread friction sensor is applicable to hexagonal screws (DIN 931), screws with hexagon socket (DIN 912), and cheese head screws with slot (DIN 84).
This thread friction sensor has a measuring range of ±100Nm for nominal thread friction torque and screw head friction torque, and a nominal pre load range of 100kN. It has an accuracy of 0.2% full scale, and sensitivity is ±0.5mV/V. This thread friction sensor can take dynamic measurements, up to a maximum of 70% full scale (peak to peak). Ultimate load is above 400% full scale.
An excitation voltage of 2 – 12 V is required. The nominal temperature range for this thread friction sensor is 5 – 45 °C, and the unit is protected to a rating of IP50.
This thread friction sensor is available in Australia and New Zealand from Bestech Australia .
