07-7311-97WP5400 | Produced by BARTEC, explosion-proof design, worry free industrial communication! ​

The BARTEC 07-7311-97WP5400 is an intrinsically safe pressure transmitter engineered for hazardous environments requiring ATEX/IECEx Zone 0/1 gas and dust certifications. Designed for critical process industries, this robust transmitter delivers precise absolute/gauge pressure measurement in explosive atmospheres containing flammable gases, vapors, or combustible dusts. The BARTEC 07-7311-97WP5400 features a welded 316L stainless steel isolation diaphragm with ceramic sensor technology, ensuring long-term stability when exposed to corrosive media like H₂S, ammonia, or chlorinated hydrocarbons. Its explosion-proof enclosure (IP66/IP68) incorporates double-sealed cable entries and hermetically sealed electronics, preventing gas ingress while withstanding high-pressure washdowns, vibration (10g RMS), and extreme temperatures. With configurable 4–20 mA HART® 7 output and SIL 2/3 capability, this device provides reliable data for safety instrumented systems (SIS) in oil refineries, chemical processing, and pharmaceutical facilities where fail-safe operation is non-negotiable.

Main Features and Advantages

Explosion Safety Engineering:

 

Dual-Barrier Protection: Integrated Zener diode barriers and galvanic isolation (250 VAC) prevent energy discharge in hazardous zones.

 

Gas/Dust Dual Certification: Single device complies with ATEX/IECEx for Zone 0/1 gases (IIC) and Zone 20/21 dusts (IIIC).

 

Hermetic Sealing: Laser-welded sensor capsule eliminates internal O-rings – critical for preventing permeation in H₂S environments.

 

Measurement Reliability:

 

Ceramic sensor immune to hydrogen embrittlement and aggressive media.

 

Automatic temperature compensation (-40°C to +125°C) maintains ±0.25% accuracy.

 

HART® 7 digital diagnostics enable predictive maintenance without process interruption.

 

Ruggedized Design:

 

Vibration-resistant construction (EN 60068-2-6 compliant).

 

Salt spray resistance (ISO 9227: 1,000 hrs).

 

Optional Inconel 625 diaphragms for seawater/chloride exposure.

 

Application Field

The BARTEC 07-7311-97WP5400 operates in high-risk processes:

 

Oil & Gas: Wellhead pressure monitoring, flare gas measurement, and separator control in offshore platforms.

 

Chemical Processing: Reactor pressure safety shutdowns (SIS) for ethylene oxide production.

 

Pharmaceutical: Sterile vessel pressure control in solvent extraction (Zone 1 ethanol vapors).

 

Mining: Hydraulic accumulator monitoring in coal processing (Zone 21 coal dust).

 

Tank Farms: Overfill prevention systems for gasoline storage (ATEX Group IIA/IIB).
