		to Tension Measurement in Suspension Cables Main Page

The LL Link is designed to measure forces and weights in an aggressive environment and conforms to the International Protection Specification Class IP 67 acc. to IEC 529.

RANGE OF APPLICATION

The LL Link is designed to measure tension forces and weights. It is made to withstand extreme environmental conditions and conforms to the International Protection Specification Class IP 67 (dust-proof and water pressure tight) acc. to IEC 529. For a very aggressive environment polyester lacquering is recommended.

FUNCTION

The tension force affecting the LL Link is measured by means of strain gauges. Four strain gauges are connected in a Wheatsone bridge and fed with a stablized voltage. The signal output from the bridge is proportional to the force on the LL Link. The signal is amplified, converted and the force (weight) is shown on the digital display (LCD) of the Remote Read-Out Instrument.

The Remote Read-Out Instrument and LL Link are operated by a built-in 9 V battery. An extension cable can be connected between the Link and Instrument.

TRANSPORT CASE

The Link and Instrument are delivered in a tough transport case with space provided for a 33 ft (10 m) extension cable.
