Product Overview

Piezoelectric Acceleration Transducers

CA series are built-in-amplifier type piezoelectric acceleration transducers designed for continuous vibration monitoring of rotating machines such as electric motors, pumps, fans and gearboxes. The transducers can be used for machine condition monitoring required by the standards such as ISO 10816, ISO 20816 and API 670.
Since iｍportance of the machine condition and diagnositic systems has increased in recent years, we have released the lower price, but high performance acceleration transducers into our lineup so the transducers can be used for the system in reasonable cost.

Features

  • Built-in-amplifier type (IEPE Type)
  • Small size and reasonable cost
  • Compliant with API standard 670 (API: American Petroleum Institute)
  • Intrinsically safe (TIIS、ATEX、NEPSI、KTL)
  • Type approval certificate for marine use
  • IP67 Dust tight and water proof
  • CE compliat, UKCA compliat

System Configuration Diagram

Mounting techniques and frequency response

The accuracy of high frequency response is directly affected by the mounting technique of the acceleration sensor. In general, the greater the mounted surface area contact between the sensor and the machine surface, the more accurate high frequency response will be.

Selection Guide of an Optimal Vibration Transducer

Measuring the health of your rotating machinery begins at the transducer. Before choosing a transducer, a thorough understanding of the machine type, application and transducer’s specifications must be taken into account.
