Introduction

The K3A155 sensor is designed to measure forces in the three components Fx, Fy, Fz. With a cylindrical profile and reduced dimensions, this 3-axis sensor is easily installed on machine tools, robot arms, and test benches. The mounting is done by 8 M16x2 threads and centering pins. Output connector MP11 24 pins. The measurement ranges are :

Option 1: 50kN in x and y, and 200kN in z.
Option 2: 100 kN in x and y, and 250 kN in z

The accuracy is about 0.2% of the measurement range, thanks to the temperature compensation of the calibration over the range -10 to 70°C, and the compensation of crosstalks. The overload capacity is 150% (i.e. a maximum allowable overload of 50% of the measuring range). The torque limit is 6000 Nm, and the maximum allowable bending moment is 2000 Nm.

Each transducer is delivered with a factory calibration certificate. Calibration to specific measuring ranges is possible (optional), as well as ISO-17025 calibration.

Packaging, Acquisition

The acquisition of the raw measurement signals is done with :

a PC or PLC acquisition system equipped with a strain gage bridge input card
or via a conditioning module for strain gage bridge with analog or digital output, then a PC or a standard acquisition system.

PM Instrumentation recommends the GSV series of digital interface conditioning modules for their ease of use and accuracy:

the GSV-4USB (Conditioner / acquisition module, 4 analog inputs) or its Bluetooth version GSV-4BT M12, which can be optionally equipped with a data logger
the GSV-8DS (High performance module, 8 analog inputs)
the GSV-6LTE, equipped with a data logger and wireless connectivity

The GSV-1A4 conditioner is equivalent to the GSV-4USB, with 4 analog outputs instead of one serial output.

A visualization and acquisition software is included with these modules (GSV-multi). Dll and VI files are also provided for the development of an application under Labview or in C / Visual Studio / C++ / .net
