Series 433, 435, 436

Barksdale_Press Transducer_433 Description
Barksdale's 430 Series Non-Incendive Transducers prevent an explosion from occurring when operated in a Division II environment. Barksdale's 430 Series, non-incendive transducers prevent personal injury and machinery damage by preventing the explosion in 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. Three models are available: Series 433 (0-5V), Series 435 (4-20mA) and Series 436 (0-10V).
