Model 372P is a piezo-electrical accelerometer permitting high temperature vibration measurements. 372P features a shear mode ceramic crystal which exhibits excellent output stability over time. With the benefit of special piezo crystal, The accelerometer transmit the acceleration signal by charge output through the low noise cable. Signal ground isolated from the outer case of the unit. The welded Inconel construction provides a hermetic housing high temperature application. The miniature 7/16-27 glass insulated connector provides long-term stability over the operating temperature range. The 372P has triangular through holes for M4 screws mounting on the test object. The 372P provides wide frequency response, which is ideal for dynamic vibration and shock measurement. Senther’s model 17P-L is a 7/16-27 to BNC breakout cable for the sensor. IN-17 charge amplifier is recommended when 372P work under high temperature environment that may cause the lower sensor internal resistance.
