MDM7000 Series Pressure Transmitters: ATEX-Certified for Hazardous Areas

In hazardous areas, instrumentation is a critical part of the safety chain. In oil & gas, chemical, and storage & transport industries, pressure measurement instruments must operate reliably under high temperatures, high pressures, and in flammable atmospheres. In these conditions, stability is essential, but high safety reliability is paramount.

Micro Sensor’s MDM7000 Series Pressure Transmitters have recently obtained ATEX flameproof certification (Ex d IIC T6 Gb), authorizing their use in Zone 1 and Zone 2 hazardous areas across Europe and other international markets.

Why it matters

ATEX sets strict EU standards for explosion protection, covering materials, mechanical design, sealing, and manufacturing control.

Achieving certification means the device:

・Avoids sparks, excessive heat, or ignition sources—even under fault conditions

・Maintains integrity under fully sealed conditions

・Is manufactured and tested under a traceable quality system

For a compact, highly integrated instrument, meeting ATEX requirements is challenging. This approval is a strong endorsement of our engineering design, product architecture, and quality management.

MDM7000 Series: Built for Long-Term Reliability

MDM7000 Series Pressure Transmitters were specifically developed for high-reliability industrial applications, designed from the outset for harsh conditions in oil & gas, chemical, and other hazardous sectors, with key parameters and structural features tailored for hazardous areas.

Key Features

・Fully welded, sealed construction for shock and vibration resistance

・Excellent temperature stability and long-term reliability

・Optional corrosion-resistant materials for complex media

・Multiple ranges and output options

・Certified for Zone 1 and Zone 2 hazardous areas (per recent ATEX approval)

These features may seem unremarkable, but in hazardous environments, reliability and long-term stability are paramount.

Key Benefits for Users

The ATEX certification acts as a “passport” for the MDM7000 Series, providing tangible advantages for users:

1. Smoother Project Bidding and Compliance

ATEX is a mandatory requirement for foreign-funded, international, or safety-compliant projects.

2. More Confident Device Selection

The MDM7000 Series already meets the required flameproof rating, eliminating concerns about on-site hazard level compatibility.

3. Reduced Supply Chain Risk

International certification ensures lifecycle stability, material consistency, and strict batch control.

4. Supports International Project Expansion

Certification gives customers a competitive edge when supplying equipment to global oil & gas projects.

Next Steps in Certification

This ATEX certification marks the first step in a comprehensive certification roadmap.

Micro Sensor will continue to pursue ATEX, IECEx, SIL, and other international certifications across more product lines, enhancing the global presence, competitiveness, and credibility of our instruments.

Our goal is to provide measurement instruments that industrial customers can trust for reliable, long-term performance worldwide.
