Transmissor de Pressão eletrônico HDA 4300 com Flush Membrane IECEx intrisecamente seguro IECEx Dustproof Enclosure IECEx que não produzam faíscas

Description:

The pressure transmitter HDA 4300 in IECEx Intrinsically Safe version has been especially developed for use in potentially explosive atmospheres and is based on the HDA 4000 series. As with the industrial version HDA 4300, the devices with IECEx Intrinsically Safe approval have the field-proven ceramic measuring cell with thick-film strain gauge.

The pressure connection is achieved with an all-welded stainless steel front membrane filled internally with a pressure transfer fluid. The process pressure is transmitted hydrostatically to the measurement cell via the pressure transfer fluid. This device is used for applications in which a standard pressure connection could become blocked, clogged or frozen by the particular medium used.

Further applications include processes where the medium changes regularly and any residues could cause mixing or contamination of the media. Intended areas of application are, for example, the oil and gas industry, in mines, or in locations with high levels of dust, e.g. in mills.

  • Accuracy: ≤ ± 0.5 % FS typ.
  • Certificate: IECEx KEM 08.0014X
  • Robust design
  • Very small temperature error
