Measurement Specialties has applied our decade ofexperience serving the automotive crash test industry to design
the ultimate crash test seat belt restraint sensor.
The EL22 provides a super low mass titanium structure tominimize F=MA errors during the crash event. All exterior
surfaces are smoothed to prevent snagging on dummy or air bagmaterials; smoothed exterior profiles protect your expensive
crash test dummy from damage while reducing drag and frictional
error. The EL22 is offered with the new fast installation axles,
unlocked by push button and a robust armoured cable exit fromthe device. The user-replaceable cable ensures that even if yourcabling is damaged, replacement cables can be rapidly wired,and your test facility remains in full operation at all times.
The low noise Wheatstone bridge consists of metal foil strain
gages which provide full scale outputs of typically 2 mV/V ofexcitation. Option B provides a linearized output signal byintegrated circuit for a better accuracy.
The quasi-static calibration procedure per ISO/TS 17242
delivers a certificate with Linear equation and a Third-Degree
Polynomial equation.
The EL22 can be configured with a variety of options to finetune the instrument to your application: select from non-standard
compensated temperature ranges, supply voltages, cable
lengths, wired connector or specify unique combinations of theseoptions.
The EL22 belt tension load cell can be fine-tuned to meetyour crash test or military test needs.
