Field of application and notes on use

The KMR are designed to measure static and dynamic compressive forces,

and are especially suitable for themonitoringof forces, e.g. with production

processes or bolted connections. Furthermore, they are used in the food industry,

for example.

The IP67 degree of protection also permits outdoor measurements to be taken.

Measuring element

The KMR have been designed as welded construction and are completely

made from corrosion-resistant, hardened steel. They can be mounted in any

position.

In the measuring element, strain gauges are connected to form a Wheatstone

bridge. The balancing elements are located in the cable end.

Therefore, do in no case shorten the cable.

The connection-cable sheathing is made from polyurethan (PUR).

Measurement, output signal

With axial forces, the measuring element is upset and the Wheatstone bridge

detuned. With a bridge excitation voltage fed, the circuit supplies an output signal

that is proportional to the change in resistance and thus proportional to

the force applied.

Measurement signal conditioning requires an electronic system (e.g. an amplifier)

that is part of the complete measuring chain.

 Disturbance variables

Torsion, bending and side forces are disturbances that may reduce accuracy

or even damage the KMR.

 Ambient temperature

To obtain optimum measuring results, the nominal temperature range of

-10...+70 oC (+14...+158 °F) has to be observed. Constant or, at the most,

slowly changing temperatures are most suitable. The specified temperature

coefficients apply to an ambient temperature changing no faster than 5 K/h.

Protection against humidity

Ambient humidity and tropical climates do not impair the function of the KMR.

The KMR complies with IP67 degree of protection according to EN60529.

IP67 means: Protection against the penetration of dust, and protection against
