Details:

Barksdale's 420X Series Explosion Proof Transducers prevent an explosion from occurring when operated in a Division 1 environment. Barksdale's 420X Series transducers prevent personal injury and machinery damage by preventing the explosion the first place. Energy generated within the transducer is of such a low level that intermittently present flammable vapors will not be ignited. External zener barriers are not required in order to meet UL requirements for a non-incendive installation. The lower cost of not having to install zener barriers means that the positive aspects of intrinsically safe and explosion proof are combined in Barksdale non-incendive transducers. Three models are available: Series 423X (0-5V), Series 425X (4-20mA) and Series 426X (0-10V).
