3 axis force sensor - ± 10 kN to ± 60kN - Ø100 mm x 72 mm

Introduction

The K3A-100 3-axis sensor is designed for measuring force in three mutually perpendicular axes. The calibration document contains the individual calibration factors and crosstalk data of the sensor. The crosstalk optionally can be minimized by application af an additional error compensation matrix.

The K3A sensors can be operated without additional compensation matrix. During the application, please take care to ensure that the maximum bending moments are not exceeded. The lever arms are calculated from the sensor origin, which is in the center of the mounting surface (on the top surface)

Specifications

The K3A100 sensor is available in 2 measuring ranges:

• 10kN (Fx) - 10kN (Fy) and 20kN (Fz) or
• 25kN (Fx) - 25kN (Fy) and 60kN (Fz)

Accuracy is about 0.2% of the measurement range, thanks to the temperature compensation of the calibration over the range -10 ) 70°C, and the compensation of crosstalks. The overload capacity is 150% (i.e. a maximum admissible overload of 50% of the measuring range). The torque limit is 1500 Nm, and the maximum allowable bending moment is 500 Nm.

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

Conditionnement, 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
