IECEx Explosion proof pressure switches
Explosionproof pressure switches are desingned to contain an explosion potentially generated by the components enclosed within it. A solid "explosion proof" or "flame proof" housing forms the basis of this protection method. It's sturdy construction with carfeully machined flame paths traps and de-energises the expanding gasses of an explosion preventing harm or damage to personal and infrastructer close by.
The explosionproof protection method has a number of benifits to those considering it's use. 1st is the ability to transmit high power into a potentially explosive environement. This could be to run a moter, pump or another high current drawing piece of machinery. Another positive of the method is it's realative simplicity of installation. An understanding of the local standards sealing fittings, conduits and housing is generally all that is necessary to ensure a sound explosion proof installation is performed correctly.
Barksdale manufactures a range of IECEx approved explosion proof pressure switches for vacuum, low, medium and high pressure applications with a full 316SS housing for environmental and spark protection.
