Product Description

IMI sensors manufacture an impressive array of loop-powered vibration transmitters with current output. These transmitters are perfectly suited for the process industry, where they seamlessly integrate with programmable logic controllers (PLCs), distributed control systems (DCS), or supervisory control and data acquisition (SCADA) systems. Designed for continuous 7x24 hour monitoring, they excel at collecting signals from critical rotating equipment. The current output effortlessly interfaces with existing monitoring systems, simplifying data monitoring and analysis.In many factories, PLC, DCS, or SCADA systems are already in place to monitor crucial parameters like pressure, flow, and temperature. IMI's loop-powered 4-20mA vibration transmitters are designed for ease and efficiency, offering a plug-and-play solution without the need for separate power supplies. Utilizing a loop power supply of 12-30 VDC, these transmitters efficiently convert current output to voltage for measurement by the process controller. Integration with existing systems is straightforward, enabling critical equipment monitoring without the need for costly additional data acquisition systems.

Equipped with a military standard connector, this transmitter ensures robust and reliable performance under demanding conditions.

Model number 640B00, 640B01, 640B02 represent the epitome of precision and reliability in vibration monitoring technology.

The compact and small size of these transmitters ensures ease of installation, even in the most confined and narrow spaces.

Perfect for monitoring slow-rotation equipment, such as fan and paper machine rollers, these transmitters deliver accurate and reliable data.

This versatile transmitter offers three selectable units of measurement: vibration acceleration, velocity, or displacement. The choice of measurement unit depends on the frequency, offering flexibility based on your specific needs. The accompanying table provides general guidelines on measurement unit selection for varying frequency ranges.
