Series 423X, 425X, 426X Explosion-Proof Transducer
Brand: BarksdaleBarksdale'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)
- Series 426X (0-10V)
- 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 (psi: 2,000 (kPa: 13,790, bar: 137.9) and above)
- cULus, CE approved
