 The Endevco Model 26B ISOMIN™ is an extremely small,
adhesive mounted piezoelectric accelerometer with integral
electronics, designed specifically for measuring vibration
on very small objects. The unit weights only 0.2 gm, reducing
unwanted mass loading effects. The "B" version of Model
25 offers a flexible, detachable coaxial cable which can
be replaced by the user in the field. This feature provides
extended service life when repetitive installations or
heavy use are expected. As with the "A" version, Model
25B is ideal for measuring vibration in scaled models,
small electronic components and biomedical research. An
optional triaxial mounting block (Model 2950M16) is available
for setting up three-axis measurement.
The Model 26B features Endevco's Piezite® Type sensing
element operating in shear mode. The internal electronics
inside the accelerometer convert high impedance input
into low impedance voltage output through the same cable
that supplies the required 4 mA constant current power.
Signal ground is isolated form the mounting surface of
the unit by a hard anodized surface. A removal tool is
included for proper removal in the field. A 4,000 g's
full scale range is available in the 25BM1 version.
Endevco Signal Conditioner Models 133, 4416B, 2792B, 2793,
2775A (set to 4 mA +/-0.5 mA), are recommended for use
with this accelerometer.
Features:
• Low impedance output
