Barksdale's 420X Series Explosion Proof Transducers are available in three different versions.
The 423X is available with a 0 – 5 VDC Output, the 425X with a 4 – 20 mA output and the 426X is available with a 0 – 10 VDC output.
The Barksdale Atex pressure transmitters have been designed to prevent an explosion from occurring when operated in a Division 1 environment.
Barksdale's 420X Atex 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 vapours 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.
Standard accuracy is +/- 0.25% full scale.
