DESCRIPTION

The ENDEVCO

Model 25B ISOMIN

™

is an

extremely small, adhesive mounted piezoelectric accel-

erometer with integral electronics, designed specifically

for measuring vibration on very small objects. The

unit weighs 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 25B 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 from

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.
