• Ultra rugged low-mass titanium design
• Seat belt restraint testing
• Tension only
• Replaceable cable
DESCRIPTION
Measurement Specialties has applied our decade of experience serving the automotive crash test industry to design
the ultimate crash test seat belt restraint sensor. The EL20-S458 provides a super low mass titanium structure to
minimize F=MA errors during the crash event. All exterior surfaces are smoothed to prevent snagging on dummy or
air bag materials; smoothed exterior profiles protect your expensive crash test dummy from damage while
eliminating drag and frictional error. The EL20-S458 is offered with optional ultra low mass slotted titanium axles and
super robust armoured cable exit from the device. The user-replaceable cable ensures that even if your cabling 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 of excitation. The EL20-S458 is also available with internal linearization (Option B) to provide +/- 0.5% FS
maximum nonlinearity. Option C provides linearization and high level output of 0.5 to 4.5 V. The EL20-S458 can be
configured with a variety of options to fine tune the instrument to your application: select from several standard
compensated temperature ranges, slotted or knurled axles, input voltages, lead lengths or specify unique
combinations of these options. The EL20-S458 belt tension load cell can be fine-tuned to meet your crash test or
military test needs.
