Xi'an Qintai Automotive Emission Technology Co. Ltd., a national high-tech enterprise since 2001, brings you industrial-grade Pressure transmitters ATEX safe engineered for explosive atmospheres. Our transmitters comply with ATEX 2014/34/EU directive and feature 316L stainless steel housings with piezoresistive sensing elements. With protection concepts including Flameproof (Ex d) and Intrinsic Safety (Ex i), these devices operate reliably from -40°C to +120°C. Backed by our ISO9001, IATF16949, and Ex certifications, plus 58 invention patents, we deliver accuracy of 0.1% to 0.5% FS. As China's No.1 OEM supplier with annual production exceeding two million sensors, we serve Weichai Power, Yuchai Power, and Quanchai Power with proven enterprise-level performance.

Working in unsafe situations requires more than standard gear. You require rebellious that avoid start sources in Zone 0, Zone 1, or Zone 2 ranges where combustible gasses or combustible clean exist.
Standard weight transmitters can gotten to be disastrous start focuses. A single start in the off-base environment leads to blasts, wounds, and office shutdowns. That's why administrative bodies order ATEX compliance for your European operations.
The item unravel three basic torment focuses for your operations. To begin with, they kill fire dangers in oil and gas handling through explosion-proof development. Moment, they guarantee you pass worldwide security reviews without compliance crevices. Third, they convey high-precision information from unsteady airs without compromising electrical integrity.
Our transmitters utilize two essential assurance concepts based on your particular risk classification. Ex d (Flameproof) development contains inner blasts inside heavy-duty lodgings, avoiding fire proliferation to encompassing environments. Ex i (Inherent Security) plan limits electrical vitality to levels unable of touching off dangerous mixtures.
Both plans join Hastelloy or 316L stainless steel development. This fabric determination gives predominant resistance to destructive chemicals, salt splash, and mechanical solvents you experience daily.
Piezoresistive and ceramic detecting components provide long-term drift-free execution. Coordinates temperature recompense keeps up precision over extraordinary warm ranges. Tall EMI/RFI protecting anticipates flag impedances from mechanical electrical frameworks and engine drives.
Our transmitters meet IECEx, ATEX, and SIL2/SIL3 utilitarian security benchmarks. Indeed in disappointment states, the gadget remains naturally secure, securing your workforce and resources.

Your wellhead monitoring and mud pump control systems operate in concentrated hydrocarbon atmospheres. Salt spray and extreme weather demand robust construction. Our transmitters withstand these harsh marine conditions while maintaining measurement precision.
Reactor vessel monitoring during exothermic reactions creates dual hazards. Volatile solvents create flammable atmospheres while combustible powders generate dust-ignition risks. Dual-certified II 1 GD transmitters handle both gas and dust environments simultaneously.
Methane digesters and pipeline systems combine moisture, hydrogen sulfide, and flammable gas. This corrosive, explosive combination requires specialized sensing solutions. Our Pressure transmitters ATEX safe deliver reliable data without creating ignition sources in these challenging applications.

We collaborate with industry-leading organizations across automotive, energy, and industrial sectors. Our partnerships with Weichai Power, Yuchai Power, and Quanchai Power demonstrate our commitment to quality and reliability. These relationships have established us as the preferred supplier in China's pressure sensor market.

Each transmitter ships in protective packaging designed for international transport. Anti-static materials protect sensitive electronics. Shock-absorbing inserts prevent mechanical damage during handling.
Documentation accompanies every shipment including calibration certificates, ATEX declarations of conformity, and installation guides. You'll have everything needed for compliant installation and commissioning.

Q: What's the distinction between Ex d and Ex i protection?
A: Ex d (Flameproof) contains inside blasts inside heavy-duty lodgings that anticipate fire engendering. Ex i (Inherent Security) limits electrical vitality to levels deficiently to touch off encompassing climates. Select Ex d for tough applications and Ex i where circuit vitality control is preferred.
Q: Can I utilize one transmitter for both gas and tidy hazards?
A: As it were if the gadget carries double certification such as II 1 GD. The "G" shows appropriateness for Gas situations whereas "D" certifies Clean environment compatibility. Continuously confirm your transmitter's checking matches your risk classification.
Q: How regularly ought to I recalibrate my ATEX transmitters?
A: Industry best hone prescribes yearly recalibration to confirm precision and distinguish sensor weariness. Your particular handle conditions may require more visit confirmation. Keep up calibration records for security audits.
Q: Do all ATEX transmitters require security barriers?
A: Security obstructions or galvanic isolators are required for Natural Security (Ex i) circles to constrain circuit vitality. Flameproof (Ex d) establishments regularly do not require obstructions since the lodging itself gives protection.
Q: What if my transmitter lodging gets damaged?
A: Any scratches, marks, or physical harm can compromise explosion-proof keenness or IP appraisals. Halt utilizing the gadget promptly. Have it assessed by certified specialists or supplant it to keep up location security certification. Never endeavor field repairs on ATEX equipment.
Q: Are your transmitters certified for North American markets?
A: Contact our specialized group for particular territorial certifications. We hold different worldwide endorsements and can direct you on proportionate guidelines for your location.
