DST P140 pressure transmitter with digital possibilities designed to provide unrivaled reliability and durability

The DST P140 pressure transmitter is designed to provide unrivaled 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 and benefits


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.


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.


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.


The new and modular electronics platform enables customers to fine-tune the sensor performance specific to their application.

The DST P140 pressure sensor is designed for the water pump and air compressor markets.

Water distribution
Better pressure control in water pumps reduces water and energy loss significantly in the water industry.

Air handling
Industrial air compressors – with piston or screw technology – for low, medium, and high-pressure applications.

Welcome to Water Industry 4.0

Thanks to growing possibilities in computer and information technology, digitalization is playing an increasingly important role in the water industry.

Pressure management is key throughout the water cycle

Global Director at Danfoss Drives Segment, Mads Warming, explains why there is a need for more efficient water supply and treatment on a global scale.
