About the MDM7000-LP Smart differential pressure transmitter

The MDM7000-LP is a high-performance differential pressure transmitter designed for critical industrial applications where remote diaphragm seals are required. These seals allow for accurate pressure measurement in systems with high temperatures, aggressive chemicals, or difficult-to-access pipework, such as tanks, reactors, or distillation columns.

Key features

• Remote diaphragm seal design: ideal for extreme process conditions including high temperature, corrosive media, or long-distance tank installations.
• High accuracy & long-term stability: delivers up to ±0.2% URL accuracy and ±0.2% span stability over 10 years, even under fluctuating conditions.
• Modular, certified, and flexible: supports HART & Bluetooth, multiple flange types and fill fluids, with certifications for global hazardous environments.
  

Further description

Equipped with monocrystalline silicon sensor technology, the transmitter provides ±0.2% URL accuracy, a 100:1 turndown ratio, and long-term stability of ±0.2% span over 10 years. The modular design supports a wide range of flange standards (EN, ANSI, HG/T), pressure classes (up to PN100/Class 600), and custom capillary lengths up to 10 meters. It’s available with a variety of wetted materials including 316L, Hastelloy C, Tantalum, Titanium, and more for excellent chemical resistance.

The transmitter supports 4–20mA HART communication and offers optional Bluetooth, high-accuracy calibration, and integrated valve manifolds for easy setup and maintenance. Its IP67 housing and intrinsically safe or flameproof certifications (ATEX, IECEx, CSA, NEPSI, EAC, etc.) make it suitable for deployment in hazardous areas across chemical, oil & gas, marine, and power generation industries.

Typical applications

Thanks to its remote diaphragm seal design, wide configurability, and high accuracy, the MDM7000-LP is ideal for:

• Chemical and petrochemical: for level, flow, and pressure measurements in reactors, separators, and corrosive fluid systems
• Oil and gas: accurate monitoring in pipelines, offshore platforms, and process skids—especially in hazardous areas
• Power generation: for pressure drop measurement across filters, turbines, and high-pressure steam systems
• Marine & offshore: approved by CCS, DNV, ABS, etc., ideal for ballast systems and engine room monitoring
• Water & wastewater: monitoring differential pressure across membranes and filters in treatment facilities
• Food & pharmaceutical (when configured accordingly):
  For hygienic pressure measurement in CIP/SIP processes with PTFE or gold-plated diaphragms

The MDM7000-LP is suitable for outdoor installations, aggressive media, and areas exposed to mechanical stress or thermal fluctuations.
