Product Description

IMI Sensors crafts an exceptional range of loop-powered vibration transmitters designed for current output, perfectly suited for the process industry. These transmitters excel in environments where programmable logic controllers (PLCs), distributed control systems (DCS), or supervisory control and data acquisition (SCADA) systems are employed to gather continuous, round-the-clock monitoring signals from vital rotating machinery. Seamlessly interfacing with existing monitoring systems, the current output facilitates straightforward data monitoring and sophisticated analysis.In most industrial settings, PLC, DCS, or SCADA systems are already set up to oversee parameters like pressure, flow, and temperature. IMI's loop-powered 4-20mA vibration transmitters offer seamless integration with a plug-and-play setup, leveraging loop power instead of needing separate dedicated power sources. With a simple loop power supply ranging from 12-30 VDC, these transmitters are powered efficiently, and the process controller adeptly transforms the transmitter's current output into a measurable voltage. This allows for the effortless monitoring of essential equipment without incurring the costs of additional data acquisition systems.

Transmitter designed for M12 connector compatibility.

656A9X Series

Compact yet powerful, this piezoelectric accelerometer can be easily installed in confined spaces, delivering superior accuracy and frequency response.

Perfectly engineered for monitoring slow rotation machinery such as fans and paper machine rollers, ensuring optimal performance and reliability.

This versatile transmitter offers three selectable measurement units: vibration acceleration, velocity, or displacement. The choice typically depends on the frequency, with the accompanying table offering general guidelines for selecting the appropriate unit for varying frequency ranges.
