Acceleration Sensor

The model MNPZE-55 is a general purpose Piezoelectric accelerometer

The unit features a top connector mounting convenience in limited space.

The accelerometer is a self-generating device that requires no external power

source for operation.

The model MNPZE-55 have crystal/Quartz/Ceramic element operating

in annular shear mode. This sensor exhibits low base strain sensitivity, high resonance

frequency, and excellent output stability over time.

Signal ground is connected to the outer case of the unit and, when used with an isolated

mounting stud, the accelerometer case is electrically isolated from ground .

A low-noise coaxial cable is supplied for error-free operation.

a small. Low-cost piezoresistive acceleration sensor suitable for automotive applications such as advanced breaking control and suspension control systems has been developed.

a piezoresistive semiconductor sensor has such advantages as high output linearity, long-term output repeatability and dc response a piezoelectric sensor doesn't feature. One drawback. However, is that piezoresistive characteristics are quite temperature sensitive: such that temperature dependence of dc offset and span have to be compensated with a certain electrical circuit. With 1 mv/vs/g, the low sensitivity of the acceleration sensor [vs:bridge voltage. G:gravitational acceleration], the temperature shift of dc offset represented in terms of the sensitivity, becomes relatively high

The MAS 501 is a general purpose accelerometer that is especially useful for measuring very low Frequencies. Compared with oil damped Accelerometers, the air-damped MAS 501  is less Sensitive to temperature variations, thus Providing more accurate measurements. The sensing element is fitted with a fully Temperature-compensated Wheatstone bridge comprised of high stability, micro-machined silicon strain gauges. Packaged in a rugged Aluminum alloy case, the MAS 501 Accelerometers are designed to be easy to mount.
