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 accuracy Explosion proof enclosure for hazardous locations Superior EMI, ESD and RFI protection Rugged stainless steel construction NEMA 4X, 7 and 9 ATEX/IECEx certification for 425X Series only Modular concept Built-in high pressure snubber (2000 PSI and above) cULus, CE approved Applications: Oil & gas pipelines Oil patch Petrochemical plants Refineries Pulp and paper mills Coal and oil fired power plants Cement plants Gas transfers for fuel systems Gas panels Gas mixing systems State of California Proposition 65 WARNINGCancer and Reproductive Harm - www.P65Warnings.ca.gov.
