CA Series
Compact piezoelectric Acceleration transducers. Responds to a wide frequency range.
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

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. The following table is an overview of applications for displacement, velocity and acceleration measurements. Please consult a vibration expert to find out what is right for your plant.
