Introduction

The 3-component sensor K3R110 is a simple, accurate and affordable solution for measuring the force Fz and the moments Mx/My simultaneously, in a minimal space (thickness: 14 to 20 mm).

The K3R110 sensor consists of an outer ring, integral with the frame, and an inner ring, integral with the sample, connected by 4 instrumented beams with a complete strain gage bridge. A 25 mm diameter bore allows the passage of a shaft, an electrical or hydraulic connector.

The K3R110 can also be used as a 3-axis Fx/Fy/Fz force transducer, by dividing the torque values by the distance between the transducer center and the point of introduction of the forces when this is known.

Specifications

8 versions are available, with force measurement ranges between ±50N and ±5kN, and torque measurement ranges between ±1Nm and ±100 Nm. The accuracy is 0.1%.

The 50N/1Nm, 100N/2Nm and 200N/4Nm versions are made of aluminum alloy, the 200N/4Nm, 500N/10Nm, 1kN/20Nm, 2kN/40Nm and 5kN/100Nm versions are made of high strength stainless steel 1.4542.

Installation

The 3-component load cell **K3R110** is easily installed on machine tools, arms, or test benches. The introduction of the forces and the fixing to the bench are carried out by 2 x 4 M6 tappings (inner circle: 50mm, outer circle: 100mm) + 4 centering pins Ø6,5 mm.

The sensor is supplied with 5 VDC. The operating temperature range is -10 to 85°C. The output signal is not amplified. The sensor is delivered with a 3m cable.

Conditioning, Acquisition, Use of the decoupling matrix

The force vector L [Fz; Mx. My] is obtained by applying a matrix A to the 4 output signals U of the K3R110. The decoupling matrix A, with 12 terms, is identified during the calibration and specific with the sensor.

A Ch 1 Ch 2 Ch 3 Ch 4
Fz a11 [N/mV/V] a12 [N/mV/V] a13 [N/mV/V] a14 [N/mV/V]
Mx a21 [Nm/mV/V] a22 [Nm/mV/V] a23 [Nm/mV/V] a24 [Nm/mV/V]
My a31 [Nm/mV/V] a32 [Nm/mV/V] a33 [Nm/mV/V] a34 [Nm/mV/V]

We recommend the following modules for signal conditioning and acquisition:

The visualization and acquisition software included with these modules (GSV-multi) has the ability to apply the A decoupling matrix on the output signals of the K3R110, allowing direct acquisition of real forces.
