Intrinsically Safe devices are engineered to operate in areas classified as a ‘hazardous area.’ This means that the environment or atmosphere in the area is flammable/explosive. The device must be designed in a way that it cannot create a spark and ignite the atmosphere. Proportion-Air is planning to make our DS Series pressure transducer intrinsically safe (I.S.). We have already received an I.S. rating for our QB Series electro-pneumatic controller. Since the DS Series transducer is often used as a secondary loop to enhance accuracy and response time, we aim to ensure it is also certified for intrinsic safety when used alongside the QB unit. This project will involve modifying the DS Series circuit board to meet I.S. requirements and documenting all necessary compliance and certification processes. Picture 1 is a ISQBX intrinsically safe electro-pneumatic controller that is currently I.S. rated. Picture 2 is a DS series pressure transducer that we are wanting to put through I.S. testing and rating. Picture 3 How we plan to use the two units together in hazardous locations.
