Presentation

The KR111 is an annular force sensor (load ring type) designed for tension and compression force measurement. Its low-profile design — 30 or 31 mm height for a diameter of 111 mm — allows integration into assemblies with limited axial space. Force is introduced through the central opening, ensuring uniform and reproducible load distribution across the sensing structure. The electrical connection is provided by an M12 connector.

The accuracy class of the KR111 sensor is 0.1, making it suitable for test bench, quality control and industrial automation applications requiring precise and repeatable measurement. The mechanical construction is dimensioned for repeated load cycles in industrial environments.

Main specifications

Parameter	Value
Nominal force	±1 kN, ±2kN, ±5kN, ±10 kN, ±20 kN, ±50kN
Measurement direction	Tension and compression (Fx)
Accuracy class	0.1
Connector	M12
Height	30 mm / 31 mm
Diameter	Ø 111 mm

Mechanical integration

Mounting is performed from the tool side, without requiring complex auxiliary fixings. The central opening guides the loading axis and ensures coaxiality of the applied force. This arrangement simplifies insertion of the sensor into an existing force transmission chain (press, actuator, test frame). The annular design also allows threaded rods or bolts to pass through the sensor for instrumented clamping applications.

Data acquisition

The KR111 delivers a strain gauge bridge signal (mV/V) via M12 connector. This signal is compatible with all conditioners in the GSV range, notably the GSV-3USB which provides signal conversion, bridge excitation and USB transmission to a PC. The signal can also be connected to a conditioner with analogue output (0–10 V, 4–20 mA) for interfacing with a PLC or industrial controller, or to a process display for local visualisation.

Calibration

Each KR111 sensor is delivered by default with a factory-established sensitivity report. For applications requiring formal metrological traceability, documented factory calibration or ISO 17025 accredited calibration (COFRAC equivalent) is available as an option on request. These services enable compliance with quality system requirements (ISO 9001, IATF, etc.) and periodic verification procedures.
