IMI Sensors Universal Transmitter Provides 24/7 Industrial Vibration Monitoring

IMI Sensors  model 682A16 is a Universal Transmitter, a DIN rail mounted, relay module with optional detachable front panel LCD display and programmer (Model 070A80 sold separately) for industrial monitoring, control, and alarm requirements. The 682A16 provides loop power for 2-wire, 4-20 mA sensors and ICP excitation for analog 8 mV/g to 120 mV/g accelerometers. It also accepts a variety of sensor input signals including mA, Thermocouple, RTD, Linear Resistance, and Potentiometer.  The transmitter is designed to protect plant and process machinery including pumps, motors, fans and other critical rotating equipment.

IMI Sensors Adds ATEX Approval to its Series 686B Smart Vibration Switch

With ATEX as well as CSA approval for use in hazardous environments, IMI Sensors Series 686B USB Programmable Smart Vibration Switch is positioned to address protection of cooling towers, fin fans, pumps, HVAC systems, and other critical machinery operated in hazardous areas.

Based on an embedded piezoelectric accelerometer, the switch monitors vibration velocity for more consistent results, and improved reliability over mechanical designs. The switch has a remote reset capability and USB programmable threshold and time delays to avoid false tripping. Since the Series 686B has only to wires, it can easily replace legacy switches.

Accelerometer Operates in Continuous 260°C Environment

Designed for monitoring vibration in gas turbines, Meggitt Sensing Systems Endevco Model 6222S accelerometer is a piezoelectric design with sensitivities of either 20, 50 or 100 pC/g. The sensor’s piezoelectric technology does not require an external power supply. The unit’s balance differential output allows its use with any industry differential charge amplifier. The sensor’s packaging is a standard ARINC three-point mounting configuration using three mounting bolts. The unit has an integral two-pin 7/16-27 UNS-2A threaded receptacle as standard with an available three-pin option. 

In addition to gas turbine measurements the accelerometers are also well suited for high temperature and high reliability vibration monitoring in helicopter Health & Usage Monitoring Systems (HUMS) as well as ground and onboard aircraft engine monitoring.
