Effective and affordable monitoring of smaller machinery

     While machine monitoring is essential in many manufacturing and industrial applications, not all applications require significant investments in high-integrity, stand-alone MMS (Machine Monitoring Systems) or MPS (Machine protection systems). However, constant attention to critical rotating machinery remains an important requirement to help provide its smooth operation and avoid potentially catastrophic failures.

     Sensonics recognizes the increasing need for continuous protection and monitoring of small rotating equipment such as fans and blowers, centrifuges, pumps, motors and conveyors. To meet this need, they developed the PZDC accelerometer, a versatile solution with multiple options. These two-wire (+ screen) loop-powered 4-20mA sensors have become an established means of small machine monitoring for a wide range of industrial applications.

     A key reason for the success of this flexible, cost-saving solution is that the accelerometer (g) or velocity (mm/s) vibration transmitter can be connected directly to an existing DCS (distributed control system), PLC (Programmable logic controller), BMS (building management system) or SCADA system.

     PZDC is available as a standard general-purpose device, or with an intrinsically safe option, for use in hazardous areas with potentially explosive environments, including hydrogen or dust, conductive or non-conductive, and also in mines with methane and dust. Submersible versions are also available with polyurethane cables and IP68 (10bar) seals, as well as special design options for subsea applications, utilizing professional corrosion resistant materials and over-molded cable inlets to withstand greater pressure.

     The PZDC can be offered with a top, side outlet integrated cable, or an integral connector and separate connector cable assembly, with standard (plain) or armor options as well as the more specialized LSZH option.
