Description Specifications Literature Description 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 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. 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).Features:Diffused silicon sensor for high accuracyExplosion proof enclosure for hazardous locationsSuperior EMI, ESD and RFI protectionRugged stainless steel constructionNEMA 4X, 7 and 9ATEX/IECEx certification for 425X Series onlyModular conceptBuilt-in high pressure snubber (2000 PSI and above)cULus, CE approvedApplications:Oil & gas pipelinesOil patchPetrochemical plantsRefineriesPulp and paper millsCoal and oil fired power plantsCement plantsGas transfers for fuel systemsGas panelsGas mixing systems State of California Proposition 65 WARNINGCancer and Reproductive Harm - www.P65Warnings.ca.gov.
