Description

The LR-Cal LFC 80 is a torque bench for static measurements, composed of a digital indicator and a strain gauge torque, extremely rugged and compact with a precision better than 0.20%.
It is ideal for the calibration and control of torque wrenches, screwdrivers, direct reading and snap.

The indicator is powered by a Li-Ion chargeable battery with an autonomy of 80 hours, with the AUTO POWER OFF function, which occurs when there are not changes in measurement for a programmable period of time.

It allows in static mode a very high resolution and in PEAK mode an acquisition frequency of 4800 measurements per second.

The instrument and PEAK functions are working in clockwise direction as well as in counter-clockwise direction.

The display of the LR-Cal LFC 80 can be rotated by 90° to be able to work both, horizontally and vertically (using the optional 90° bracket).

The device is equipped with an USB 2.0 interface with a transmission rate of 4800 values per second in PEAK mode. A programmable "First PEAK" function makes it easy to avoid mistakes during calibration of torque wrenches.

For gradual and continuous reproducable movements of torque wrenches we recommend the mechanical support code LR-Cal LFC-ATC:

LFC-ATC support tool

LR-Cal LFC-ATC mechanical support with LR-Cal LFC 80 torque meterMechanical support LR-Cal LFC-ATC

The mechanical support LR-Cal LFC-ATC comes with a double linear guide for the calibration and control of release or direct reading keys which allows the application of the load in a gradual and continuous way, by respecting the reference norm EN ISO 26789 (2004).

Code LFC-ATC-1000 for ranges to 1000 Nm, incl. 1 base plate for 1 LR-Cal LFC 80
Code LFC-ATC-2000 for ranges to 2000 Nm, incl. 1 base plate for 1 LR-Cal LFC 80

If the mechanical support LR-Cal LFC-ATC shall be equipped with further LR-Cal LFC 80 instruments, you can increase the calibration range of your equipment.For each additional LR-Cal LFC 80 you need an additional base plate order-code LFC-PLATTE.

LR-Cal LFC-ATC mechanical support with LR-Cal LFC 80 torque meterExample: to cover a range of 1 to 1000 Nm in class 1, you need three LR-Cal LFC 80 instruments, to be mounted into the
LR-Cal LFC-ATC mechanical support:
1 x code LFC80-0010 = range 0...10 Nm
1 x code LFC80-0100 = range 0...100 Nm
1 x code LFC80-1000 = range 0...1000 Nm
2 x code LFC-PLATTE = two additional base plates
1 x code LFC-ATC-1000 = mechanical support incl. one base plate
