 Danfoss DST P140 Pressure Transmitter for Water and Air Applications

The DST P140 pressure transmitter is designed to provide unrivalled reliability, durability, performance, and not least, digital possibilities in the water-pump and air-compressor markets. MEMS technology, stainless-steel design, and a hermetically sealed media interface ensure that the transmitter can withstand even the harshest application environments. And, thanks to its diagnostics features and scalable electronics platform, the DST P140 is capable of automatic sensor failure detection – and can also scale sensor performance to the specific application and adapt to applications faster with "test-to-failure" methods and documentation.

Features

  • Hermetically sealed media interface (all stainless steel, fully welded)
  • Compact and cost effective design for OEM applications
  • Superior shock and vibration resistance
  • High overload and burst pressure
  • Robust electronics platform for harsh electrical environments
  • Precision
    The DST P140 provides a +/- 2% Total Error Band across the application-focused temperature range. Custom calibration profiles can be adapted to suit application-specific requirements - supporting a more efficient  superheat control as a result.
  • Reliability
    Optimized product packaging of the MEMS sensor and the signal-conditioning electronics deliver excellent vibration resistance, thermal management properties and protection against moisture ingress.
  • Thorough testing
    A "test-to-failure" method is an important part of the Danfoss product-development process, providing increased product-design and specification insight. This method also allows for faster optimization and testing, improving time-to-market.
  • Future-proof
    The diagnostic capabilities of this transmitter will benefit customers today — saving on troubleshooting costs — and well into the future, as more and more products have integrated electronic capabilities.
  • Scalability
    The new and modular electronics platform enables customers to fine-tune the sensor performance specific to their application.
