PDTN12S25-D Presigo (PDTN…) - Differential pressure transmitters
Engineered for performance in the toughest environments, the Presigo PDTN differential pressure transmitter combines a sleek, IP54-rated design with advanced capabilities. Its high-contrast shine-through display remains clear even from a distance, while a versatile range of available pressure sensors ensures you’re ready for both current and future demands. Seamless integration with native support for BACnet, Modbus, and EXOline in communicating models, plus analogue models offering configurable 0–10V or 4–20mA outputs for simple, precise measurements. Designed for both positive and negative pressure applications such as cleanrooms, hospitals, and other mission-critical spaces. The PDTN guarantees accurate monitoring where it matters most. Installation is effortless thanks to generous wiring space, clearly marked PCBs, and an intuitive rotary switch. Quick commissioning via the Regin:GO app gets you up and running in no time, so you can focus on performance, not setup. Presigo PDTN – where innovation, accuracy, and ease of use come together.
