Read-Out Instrument

The LL Link and LLA load links can be used as a force transmitters for weighing and measuring tension forces. The LL and LLA are suitable as transmitters and overload guards, for overload protection and load indication. The LL-Link without transducer amplifier has an output of approx. 1,7 mV/V. The LLA-Link with built-in transducer amplifier has an output of 4-20mA.

LL-Link function

The tension force affecting the LL-Link is measured by means of strain gauges. Four gauges in a Wheatstone bridge are fed with a constant voltage. The output signal from the bridge is proportional to the force on the LL-Link. The transducer amplifier of the LLA amplifies and converts the signal to a current signal of 4-20mA which is resistant to interference. The amplified signal can be transmitted over distances of at least 500 m.

The signal can be connected to a PLC Programmable Logic Controller or to any Gigasense Electronic Unit. The Gigasense Electronic Units are provided with outputs for alarm and switch functions for indicators and signal processing.
