138.02 : Triaxial Piezo Side (Compact)

General Characteristics (metric): M12 glass seal connector, Dimensions = 1.65x1.12 inch, Height = 0.65 inch,  weight=3.0 Oz, 120°C, 1/4" 28 UNF thread.

For precise vibration monitoring in challenging industrial settings, the hermetically sealed triaxial piezoelectric accelerometer model 138 is an excellent solution. It features the industry-proven ICP® 2-wire voltage transmission (minimum 2 mA constant current) for reliable operation. Enjoy accurate and stable measurements thanks to its isolated signal ground, which prevents ground loops, and Faraday shielding, which reduces ESD interference. The innovative annular shear mode design ensures consistent readings by preventing errors from thermal transients and high transverse vibrations. Moreover, its low-noise electronics and temperature compensation deliver consistent accuracy throughout its entire operating temperature range. With a wide array of frequency ranges available, this accelerometer can address nearly all customer needs.

Typical applications: 

These accelerometers are designed for vibration measurement in the demanding environments of industrial machinery monitoring. The high-frequency variant is suitable for monitoring vibrations in components such as rolling element bearings and detecting pump cavitation. The medium-frequency variant is appropriate for assessing the overall vibration levels of equipment like pumps, motors, and fans.
