Applications of the SEJ-Z Sensor<\/strong><\/span><\/h2>\n

The SEJ-Z mechanical stop-type force sensor is used in any application where the measurement of average forces must be combined with robust overload protection:<\/p>\n

Laboratory test benches<\/span><\/strong>
\nMeasurement of tensile and compressive forces on samples that may fail suddenly (brittle materials, films, adhesives, seals). The mechanical stop protects the sensor if the sample breaks, preventing the need for frequent cell replacement.<\/p>\n

Cosmetics and packaging<\/span><\/strong>
\nMeasurement of the actuation force of pumps and sprays, the opening force of closures and caps, and the tear resistance of packaging components. The load capacities ranging from 10 to 2,000 N cover the vast majority of forces encountered in these applications.<\/p>\n

Medical and Medical Devices<\/strong><\/span>
\nMeasurement of the activation force of injectors, auto-injectors, and administration devices, where the required force is a regulated safety parameter and must be measured in a traceable manner.<\/p>\n

Manufacturing and Assembly<\/span><\/strong>
\nVerification of insertion and extraction forces for snap-fit components, testing the strength of bonded or welded assemblies, and monitoring clamping forces on the production line.<\/p>\n

R&D and Product Development<\/strong><\/span>
\nCharacterization of the mechanical properties of new materials or assemblies, prototype validation, and repeatability studies requiring traceable measurements in accordance with ISO 17025.<\/p>\n

SEJ-Z vs. Mini SEJ-Z vs. SEJ: Which sensor should you choose?<\/span><\/strong><\/h3>\n

ACRN offers three families of S-shaped force sensors, designed for different measurement ranges:
\nThe Mini SEJ-Z is designed for very low loads (1 N to 5 N) and features a mechanical stop. It is designed for high-end watchmaking, electronics, and cosmetics applications where the forces involved range from a few grams to several hundred grams.
\nThe SEJ-Z is designed for medium loads (10 N to 2,000 N) and features a mechanical stop. This is the versatile solution for laboratories, test benches, and quality control stations where the risk of overload is a real concern.
\nThe SEJ covers high loads (15 daN to 3,000 daN) without a mechanical stop, offering superior accuracy (0.02% EM vs. 0.05% PE for the SEJ-Z). It is recommended for high-precision metrological applications where the risk of overload is controlled.<\/p>\n
