Perpetua Power Pucks thermoelectric energy harvesters are now certified ‘Intrinsically Safe.’

The introduction of Intrinsically Safe products has been driven by a growing use of wireless sensors throughout industrial applications that monitor critical processes or equipment health where the highest environmental safety standards are required, according to the company.  Perpetua's new certifications cover Classes I, II, III, and include protection from dust and water immersion, with an Ingress Protection rating of IP67.  

Environmentally friendly Power Pucks rely on temperature differences to generate long-life, continuous, renewable energy for wireless sensors.  A benefit for customers is that near real-time data can be captured with rates as fast as every second, resulting in increased input for analysis and modeling, important to efficiently managing processes like enhanced oil recovery.

The new Intrinsically Safe products are available now to meet the power requirements for industrial wireless sensors in hazardous locations.  The Intrinsically Safe label assures customers that Power Puck energy harvestors will not exceed ignition levels critical in facilities like refineries and agriculture processing where continuous ignitable concentrations of liquids, vapors or dust exist.
