A Revolutionary Addition to the field of 4-20 mA Vibration Trending

IMI Sensors, the same company that revolutionized the vibration switch industry with its line of USB programmable models, announces another groundbreaking design: the model 653A01 Ultra Low Frequency Displacement Sensor. Ideal for monitoring vibration on slow speed rotating equipment, the sensor is loop-powered with a 4-20 mA output that will interface directly to PLC, DCS and SCADA systems common in plant control rooms.

Until now users that wanted to monitor equipment turning at speeds below 180 cpm (3 Hz) with one simple sensor were limited in the frequency bands and scale in which they could measure. IMI’s 4-20 mA displacement sensor changes the game, allowing user’s to trend vibration in displacement at speeds as low as 90 cpm (1.5 Hz). Displacement, as opposed to the traditionally offered velocity and acceleration scales, offers the best signal resolution and consistency at speeds below 600 cpm (10 Hz) and is ideal for balancing applications.

IMI’s model 653A01 Ultra Low Frequency Displacement sensor is the perfect tool for cooling towers that demand 24/7 vibration monitoring. The unit is made of stainless steel, hermetically sealed and simple to install with a small footprint. Its 4-20 mA signal can travel long distances without suffering loss or noise issues. Two-wire and loop powered, the sensor simply plugs right in to an open channel on the plant control system. Reverse-wiring protection allows for the most simple of electrical installations.

The model 653A01 has a vibration range of 40 mils peak to peak. Its frequency span is 90 cpm to 18,000 cpm (1.5 Hz to 300 Hz), giving it the best low-frequency response of any 4-20 mA sensor on the market today. The Ultra Low Frequency Displacement Sensor is available with industry standard 2-pin MIL connector or is fully submersible when ordered with integral cable.

IMI Sensors offers a Lifetime Warranty and Best-Price Guarantee to go along with customer service and technical support that is second to none. For more information contact IMI at 1-800-959-4464.
