3-axis force sensor from ±2/2/10 kN to ±20/20/60 kN – Ø100 mm x 72 mm

Overview

The K3A100 3-axis force sensor simultaneously measures Fx, Fy, and Fz forces along three perpendicular axes. Four measurement ranges are available: ±2/±2/±10 kN, ±5/±5/±10 kN, ±10/±10/±30 kN, and ±20/±20/±60 kN. The overall accuracy is 0.2%, and transverse force sensitivity (crosstalk) is between 1 and 2%. The sensor body is made of IP65-rated steel. Overload capacity is 150% (i.e., a maximum allowable overload of 50% of the rated range). The torque limit is 1500 Nm, and the maximum bending moment is 500 Nm (4000 Nm and 1500 Nm for the highest-capacity version).

The K3A100 sensor can be easily integrated into machine tools, robotic arms, or test benches. Force introduction and stator/bench mounting are achieved via 8 M10x1.5 threaded holes, with specified tightening torques (see here). A clearance of 1 mm must be maintained between the adapter parts and the sensor body.

The sensor operates at 5 VDC supply. Operating temperature range is -10 to 85°C. The output signal is unamplified (0.8 to 1.5 mV/V depending on the axis). The 3 output signals are decoupled by sensor design and directly represent the actual forces — no additional decoupling is required. The sensor is supplied with a connector output, with a 5 m cable available as an option.

Specifications

The K3A100 is available in 2 versions:

Each sensor is supplied with a factory calibration certificate. Calibration for specific ranges is available as an option, as well as ISO-17025 calibration.

• Calibration: Standard or high-precision
• ISO-17025 certificate
• Cable

Applications

The K3A100 is recommended for:

• Robotics testing
• Machine tool instrumentation
• Production machine monitoring
• Medical equipment
• Test benches

• Measuring range
• accuracy class of the sensor
• Connections
• Mounting flanges

• the GSV-4USB (Conditioner / acquisition module, 4 analog inputs) or its Bluetooth version GSV-4BT M12, which can be equipped with an optional 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.
