The strain sensor is suitable for measuring dynamic and qua - sistatic forces on fixed or moving machine parts. The sensor measures the force-proportional strain at machine or structural surfaces (indirect force measurement). The high sensitivity and acceleration-compensated design of the sensor allows process monitoring on fast-running process machinery (e.g. presses, automatic assembly machines).

• Very high measuring sensitivity even minute forces can be accurately measured.
• Because of its low acceleration sensitivity also suitable for measurements on moving parts.
• Measuring range for tensile and compression forces.
• Extremely simple installation as sensor is secured with only one M6 screw.
• Overload-proof design.
• Degree of protection IP65 (with cable connected).
• Ground-isolated version available for eliminating noise due to ground loops (Type 9232AU41 optional available).

Description

The strain of the basic material acts via the two contact surfac- es on the sensor as a change in distance. The sensor enclosure serves as an elastic transmission element and converts the change in distance into a force. The piezoelectric elements subjected to shear strain produce an electric charge Q (pC) proportional to this force. The particular advantages compared with the familiar wire strain gage technology rest in the high sensitivity, large over - load resistance and practically unlimited life even under fluc - tuating loads. The measuring signal can be further processed as a relative value. For absolute value measurements (e.g. in N or kN), the strain sensor must be calibrated against an appropriate reference. The sensor design allows it to be used in industrial environ - ments. With its connected cable, the measuring chain satis - fies the requirements of protective class IP65. The top part of the strain sensor enclosure is made of stainless steel. A KIAG 10-32 neg. is the integrated connector. This allows the use of a broad selection of connecting cables (see notes on accessories). Application

• Monitoring of all types of machinery in C-frame construc - tion: e.g. presses and automatic assembly machines. Because of its easy installation, the sensor is ideal for retrofitting on existing machinery.
• Machine safety monitoring, e.g. protecting mechanical presses against overload.
• Quality control on manufacturing plants for joining processes, e.g. in orbital riveting, clinching or resistance spot welding.
• Monitoring machine tools, e.g. prompt detection of tool breakage or tool collision.

• Alignment of the sensor to the machine structure. The measuring axis should be positioned according to the best possible strain curve.
• The cable run close to the sensor should be as free as pos - sible from pushing or pulling forces. The cable should be clamped in place to avoid strain or vibration transmission.
