Product Description

IMI sensors present an outstanding range of loop-powered vibration transmitters, boasting a current output designed to excel in the process industry. These transmitters seamlessly gather continuous 7x24-hour monitoring signals from critical rotating equipment, interfacing effortlessly with programmable logic controllers (PLCs), distributed control systems (DCS), or supervisory control and data acquisition (SCADA) systems. By integrating directly with existing systems, they provide a straightforward pathway for data monitoring and analysis, ensuring optimal performance and reliability.In factories where PLC, DCS, or SCADA systems are prevalent for monitoring pressure, flow, and temperature, IMI's innovative loop-powered 4-20mA vibration transmitters offer a seamless plug-and-play solution. Utilizing loop power instead of a separate power supply, they can be effortlessly powered by a 12-30 VDC loop. This design allows the process controller to convert the transmitter's superior current output into a measurable voltage, ensuring seamless integration. By enabling monitoring without the need for expensive additional data acquisition systems, these transmitters represent a cost-effective approach to maintaining critical equipment efficiency.
