Historically DJB has focused on the Test & Measurement vibration market, supplying sensors for product developments in the automotive, aerospace and defence markets to name just a few, featuring miniaturisation in addition to high temperature testing to 900°C. But, with this launch, the company enters the competitive ‘low cost’ machine health monitoring market with an offering that, it says, will provide a completely new solution.

The combination of low cost and Konic Shear means significant improvements in cross-axis control without any cost penalty. DJB says this is a step up from compression and shear plate designs.

The A/140 range is sealed to IP67 and manufactured in corrosion-resistant stainless steel for use in harsh environments. At only 80g, it is 25% lighter than some of its competitors and has a low noise floor. With a range of cabling solutions available, it offers effective performance at low cost, in a package that is a direct replacement for other existing solutions.

Gary Chadwick, DJB’s operations manager said of the design: "The Konic Shear design continues to provide consistent cross-axis control despite the inevitable degradation of polarisation that occurs in all piezoelectric materials; this unique feature means the potential 40% errors that can occur in cross-axis are avoided over prolonged use, a critical aspect of accelerometer technology overlooked by 90% of users."

The A/140 IEPE accelerometer is available in several different versions:

• Mil-C-5015 2 pin top connector – A/140
• Integral top entry cable – A/140/C
• Integral side entry cable – A/140/SC
• Waterproof integral cable, top entry – A/140/W
• Waterproof integral cable, side entry – A/140/SW

Neill Ovenden, DJB’s MD, adds: "Our high temperature industrial accelerometers have been part of the UK’s power generation capability for over 40 years and these new low cost accelerometers bring that pedigree and performance to the wider industrial machine monitoring market."
