Special force transducer for friction clutch testing

A reliable test set for demanding applications

The fSENS FRKPS special force transducer is used to check the friction clutches of chain hoists by measuring shear forces. The set consists of a force transducer, chain adaptors, and a handheld indicator. Your benefits at a glance:

  • High measurement accuracy
  • Simple to use
  • Easy reading of the measured values

Product Description

To perform a test, the transducer is hooked into the chain and travels up with it until it encounters the base of the hoist, thereby locking the chain. The force required to activate the friction clutch is displayed on the handheld indicator, which is powered by a rechargeable battery. The transducer’s output signal travels to it via a cable. The indicator integrates two useful features: a maximum value memory and automatic power off when not in use. Optionally, up to 99 different datasets can be stored electronically. A large illuminated graphical display makes it easy to read measurements. For testing all chain hoists in the specified load range, two chain adaptors, and three centering sleeves are included.

Your main benefit: there is no need to wrestle with heavy test weights. A sturdy design and straightforward use make the FRKPS a valuable instrument for maintenance and repairs.
