KSI84AR - Description
The KSI84AR current loop accelerometer is built for industrial applications requiring precise vibration monitoring at higher frequencies. It outputs vibration acceleration in RMS via a 4-20 mA loop, providing real-time data suitable for direct connection to control and measurement systems, including PLCs and panel meters.
The accelerometer’s double-shielded stainless steel housing provides excellent electromagnetic interference (EMI) protection, while the M12 connector allows for simple and secure connections. The IP68 waterproof rating ensures reliable operation in harsh environments, while galvanic isolation helps protect the sensor and connected systems from electrical disturbances.
The KSI84AR series is available in various types, each offering different measurement ranges and frequency limits, making it versatile for numerous vibration monitoring tasks. This model is particularly suited for high-frequency applications, such as bearing and gearbox condition monitoring and shock vibration analysis.
