PTM/N/Ex - Programmable 4-20mA pressure transmitter Modbus

Product catalog summary
Overview: The document provides detailed technical specifications and certifications for the PTM/N/Ex Intrinsically Safe Submersible Transmitters, which are ATEX/IECEx certified and programmable with a 4-20mA output. These transmitters are designed for high flexibility and customization, suitable for use in aggressive media environments.
Customer Benefits: The transmitters are ATEX certified, offer scalable pressure ranges, and allow zero and span adjustments via software. They are available in stainless steel and titanium versions, providing durability in acidic conditions.
Technical Specifications:
  • Pressure Measuring Range: 1 to 250 mH2O with overpressure up to 3 bar and burst pressure over 200 bar.
  • Accuracy: Zero-based accuracy includes hysteresis and repeatability, with long-term stability improving through sensor ageing.
  • Temperature Range: Operating and process temperatures range from -5 to 80°C, with storage temperatures from -10 to 80°C.
  • Electrical Specifications: Resolution is 0.025% FS, with adjustable output and a power supply range of 9 to 28 V DC.
Certifications and Approvals:
  • ATEX Approval: Certified for gas and dust environments with specific temperature classes and ambient/process temperature ranges.
  • GL Approval: Certificate 60332-09 HH for field applications D, F, EMC1.
  • Additional Approvals: Includes ABS and DNV certifications.
Physical Specifications:
  • Materials: Transducer and housing made from stainless steel or titanium, with various seal options like Viton, EPDM, Kalrez, and NBR.
  • Weight: Approximately 157 g for a closed cable version.
Equipment and Accessories: Includes interface options and PC software for configuration, with detailed manuals and safety instructions available.
Ordering Information: Options for pressure type, measuring range, process connection, electrical connection, output signal, accuracy, temperature range, and additional features like special oil filling and ballast weight are provided.
