1. What Is the DST P1400 Pentair Transmitter?
DST P1400 Pentair: The DST P140 is a pressure transmitter developed by Danfoss (not Pentair) under the DST family of industrial sensor solutions. Designed for water pump and air compressor applications, the DST P140 uses MEMS (Micro-Electro-Mechanical Systems) technology, featuring a stainless-steel, hermetically sealed structure to ensure robustness and resistance in harsh environments
It’s important to note that there appears to be no product named “DST P1400” under Pentair’s or Danfoss’s portfolio. The closest match—DST P140—is likely the intended reference, and this article focuses on that real and well-documented product.
2. Key Features and Industrial Advantages
Precision & Reliability
The DST P140 boasts a ±2% Total Error Band across its application-specific temperature range.
Custom calibration profiles enable optimized performance tailored to specific uses—beneficial for tasks such as superheat control
Durability Under Tough Conditions
The transmitter’s MEMS sensor and signal-conditioning electronics are packaged to resist vibration, manage thermal loads, and prevent moisture ingress
The hermetically sealed, stainless-steel design ensures protection even in corrosive or high-pressure environments
Digital Diagnostic Capabilities
Built-in diagnostics support automatic sensor failure detection, helping reduce downtime and maintenance costs.
Its modular electronics platform allows for scalable configuration and application-specific optimization
3. Technical Specifications at a Glance
Exploring the formal specs for DST P140 reveals critical performance and physical details:
| Specification | Value |
|---|---|

| Response Time | Max 2 ms |
| Total Error Band | ±3% of Full Scale (as per one spec listing |
These specs confirm that the DST P140 is designed for precision, environmental endurance, and fast response, suitable for demanding industrial control systems.
4. Typical Applications and Use Cases
The DST P140 shines in critical sectors, particularly:
Water Distribution & Pumping Systems
Precise pressure sensing helps control pumps in municipal or industrial water systems, reducing water loss and improving energy efficiency
Air Compressor Operations
Widely used with piston and screw compressors, the DST P140 supports varied pressure ranges and ensures stable compressor performance under fluctuating conditions
Future-Ready Integration
With built-in diagnostics and scalable electronics, this sensor is well-suited for Industry 4.0 environments, enabling seamless integration into IoT systems, predictive maintenance platforms, and data-driven automation strategies
5. Certifications and Compliance
The DST P140 is backed by several certifications that underpin its reliability and regulatory conformance:
CE marking and RoHS compliance, confirming adherence to European safety and environmental standards.
Available certificates include NSF, UL, WRAS, and others for hygienic and electrical safety requirements
These approvals ensure the device can be trusted in regulated industries like water treatment, food and beverage, and electrical infrastructure.
6. Why the “DST P1400 Pentair” Reference Is Misleading
A search for DST P1400 specifically under Pentair yields no relevant results—neither product listings nor documentation suggest its existence. Instead:
Pentair is known for pool pumps, water filters, and related equipment, but no DST P1400 sensor appears in their catalog
Danfoss’s DST P140 is the only documented product with that naming convention, suggesting the proper model notation—P140, not “P1400.”
Therefore, readers and professionals should refer to Danfoss DST P1400 Pentair transmitter when seeking precise product information, not an erroneous Pentair reference.
Conclusion
The DST P1400 Pentair transmitter by Danfoss is a robust, accurate, and digitally capable sensor ideal for water pump and air compressor applications. With features like fast response, hermetic stainless-steel design, diagnostic functions, and adherence to critical certifications, it stands out as an industrial-grade component.
The mention of “DST P1400 Pentair” appears to be a misnomer or mistaken reference—no such device exists under that name in either Danfoss or Pentair’s documented offerings. To find the correct product, consider the Danfoss DST P140. If you need further guidance on sensor selection, integration into control systems, or technical configuration, I’d be happy to help!
