Clamping force measuring instruments and modules thereof

A sensor module for a clamping force measuring instrument having the following features:

• a. the sensor module has at least one force sensor for detecting a clamping force applied to measurement surfaces of the sensor module by a clamping means in a radial direction outward or in a radial direction inward relative to a center axis,
• b. the sensor module has a coupling device for coupling to an evaluation module and a data communication device for transmitting sensor data to the evaluation module, the evaluation module having a coupling device for coupling to the sensor module and a data communication device for transmitting sensor data from the evaluation module, the evaluation module further including a radio interface for communicating data to a receiver, and/or a memory for storing data for the purpose of later read-out via a cable connection or a radio connection, and/or a display device for displaying data.

A set for a modular clamping force measuring instrument for radial clamping means having the following features:

• a. the set has an evaluation module, the evaluation module having a coupling device for coupling to a sensor module and a data communication device for transmitting sensor data from the evaluation module, the evaluation module further including a radio interface for communicating data to a receiver, and/or a memory for storing data for the purpose of later read-out via a cable connection or a radio connection, and/or a display device for displaying data, and
• b. the set has a plurality of sensor modules, each sensor module having at least one force sensor for detecting a clamping force applied to measurement surfaces of the sensor module by a clamping means in a radial direction outward or in a radial direction inward relative to a center axis, and each sensor module has a coupling device for coupling to the evaluation module and a data communication device for transmitting sensor data to the evaluation module.
