IMI Sensors - A PCB Piezotronics Division Protecting Cooling Towers & HVAC Systems Reliable and Cost-Effective Vibration Monitoring Solutions for Cooling Fans and Other Low Frequency Equipment

Process Monitoring & Protection Protecting Cooling Towers Cooling towers are a critical component of production in many industries today. Most towers use a horizontal electric motor driving a jack shaft into a right angle gearbox with vertical output to a large fan. Vibration monitoring of this drive train is essential to provide signals for early warning or provide shutdown when vibration levels exceed a predetermined threshold. The classic legacy solution involved the use of “earthquake” mechanical switches. These devices utilize a spring and magnet concept and are designed to mechanically...

Electronic Vibration Switches - Process Monitoring & Protection Electronic Vibration Switch ■ Lower cost than competitive models ■ Dual set points (relays) ■ Explosion proof options available ■ On-board or remote piezoelectric USB Programmable Smart Switch ■ Programmable delays eliminate false trips ■ Competitive price compared ■ Hazardous area approvals available Mechanical Vibration Switches - Process Monitoring & Protection Mechanical Vibration Switch for less critical applications magnetically coupled ■ External reset button Mechanical Vibration Switch approved, explosions proof less critical...

Process Monitoring & Protection Heating, Ventilation & Air Conditioning (HVAC) In some cooling applications there may be a need for vibration trending or route based inspection of critical bearing and critical gearbox conditions. It this case vibration switches may not be the correct solution. IMI Sensors supplies industry leading general purpose vibration sensors to interface with any data collector used for classic condition monitoring applications. For 24/7 vibration trending the 640 Series 4-20 mA output sensors provide current signals to interface with any PLC, SCADA, or DCS panel. These...
