Intrinsic Safety

  1. 10-Point Checklist for Buying Ex Cameras

    Buying an Ex digital camera often costs many times that of its non-Ex equivalent. CorDEX has published a checklist to help potential users work their way through the maze of features. Ranging from affordable point-and-shoot models to high end compact digital SLRs, intrinsically safe refers to a method of protection that prevents ignition by spark of thermal means.

  2. Process Loop Calibration Optimises Plant Stability

    The calibration of analogue signals from myriad sensors and transducers in a process plant is essential not only to ensure correct readings on instruments but also for the feedback signals required for stable process plant operation. Continue reading →
  3. Gas Detection from Past to Present

    Testing for gasses has come a long way since the days when Victorian miners would take a canary down a mineshaft as an early warning indicator of toxic gases such as carbon monoxide, methane or carbon dioxide. Continue reading →
  4. Intrinsically Safe Measurement avoids Blasts

    We have covered the issue of intrinsic safety in a previous blog post last June. Now PASS is driving the message forward in the media, recently with a double page editorial feature written by our managing director Barry Atkins on pages 28-29 of the March 2014 Edition of Hazardex magazine, pioneer of hazardous area publishing in the UK.

  5. What is Intrinsic Safety, and What is Ingress Protection?

    Production of testers that can operate in difficult and hazardous areas is a very difficult and time consuming process; the highest levels of protection must be added so that none of the working parts can be affected and more importantly, the test instruments cannot effect the environment.
