Effective and affordable monitoring for smaller machinery

While machine monitoring is an essential necessity in many manufacturing and industrial applications, not all need the more substantial investment of high-integrity, stand-alone MMS (Machine Monitoring System) or a MPS (Machine Protection System). However, keeping a continuous eye on critical rotating machinery is still an important requirement, helping to provide its smooth running and evading the potential of a catastrophic failure.

Sensonics recognised the increasing demand for continuous protection and monitoring of smaller rotating plant such as fans and blowers, centrifuges, pumps, motors and conveyors to name a few. To meet this need, they developed the PZDC Accelerometer, a versatile solution that is available in a number of options. These two-wire (+screen) loop-powered 4-20mA sensors have become an established means of smaller machine monitoring, suitable 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 directly connected to an existing DCS (distributed control system), a PLC (programmable logic controller), a BMS (building management system), or a SCADA system.

The PZDC is available as a standard general-purpose device, or there is an intrinsically safe option for use in hazardous areas with potentially explosive atmospheres, including hydrogen or dust, conductive or non, and also for use in mines with methane and dust. Submersible versions are also obtainable with polyurethane cable and IP68 (10bar) sealing, along with specially engineered options for sub-sea applications, utilising specialist corrosion-resistant materials and over-moulded cable entries to withstand greater pressures.

The PZDC can be provided with a top, side exit integrated cable, or with an integral connector and separate connector cable assembly, standard (plain) or armoured options as well as more specialist LSZH options.
