• ®IEPE transmission mode
  • Annular shear mode
  • Dual case isolation with internal Faraday shield
  • Standard sensitivity 100 mV/g
  • Hermetically sealed (laser welded)


GENERAL CHARACTERISTICS (metric): M12 glass seal connector, Dimensions = 1.65×1.12 inch, Height = 0.65 inch,  weight=3.0 Oz, 120°C, 1/4″ 28 UNF thread.

The hermetic sealed triaxial industrial piezoelectric accelerometer model 138 is design to monitor the vibration in harsh industrial environment. It uses the industry standard ®ICP 2-wire voltage transmission technique with a 2 mA minimum constant current supply. Signal ground is isolated from the mounting surface and outer case to prevent ground loops. Faraday shielding will limit sensitivity to ESD to a minimum. Annular shear mode design will prevent from thermal transient and from spurious signal from high transverse vibrations. Low noise electronic and a temperature compensated design will give you accurate result over the complete temperature range. Large choice of frequency range will help to fit almost every customer requirements.


TYPICAL APPLICATIONS: Vibrations measurement in the rugged environments of industrial machinery monitoring. High frequency version will monitor the vibration on roller bearing, pumps cavitation. Medium frequency version will monitor overall vibration on pumps, motors and fans.


INCLUSIONS: All sensors are supplied with interchangeable M6 and 1/4″ UNF Mounting bolt options.
