Maintaining positive pressure is fundamental to contamination control in clean rooms across pharmaceuticals, semiconductor manufacturing, and healthcare. Wireless differential pressure sensors using LoRaWAN and cellular technologies (LTE-M and NB-IoT) provide a modern, low-power, and scalable approach to continuous pressure monitoring. By delivering real-time data, remote visibility, and automated alerts, these IoT solutions help facilities ensure regulatory compliance, prote

Hospital construction zones must remain under negative pressure to prevent particulates and potentially harmful airborne contaminants from migrating into occupied clinical areas. But fans, doors, and temporary barriers can make pressure stability difficult to prove—or to maintain consistently. In this guide, Ellenex explains how LoRaWAN-connected differential pressure monitoring provides near real-time visibility, threshold alerts, and reliable reporting across large faciliti

Maximize HVAC efficiency and indoor air quality with Ellenex’s NB-IoT technology. This post explores how the PDT2-N differential pressure sensor optimizes air filter performance through real-time, remote monitoring. Discover how to reduce energy costs, prevent equipment strain, and automate maintenance with LPWAN-based IoT solutions. Perfect for facility managers in smart cities and industrial hubs seeking reliable, battery-operated sensors for sustainable building management

Optimize your HVAC performance with the Ellenex PDT2-L Differential Pressure Sensor. This SEO-optimized guide explains how to eliminate energy waste caused by clogged filters through precision monitoring. Learn how LPWAN-enabled predictive maintenance reduces utility bills, prevents component strain, and ensures superior indoor air quality (IAQ). Ideal for facility managers seeking smart building IoT solutions to automate filter replacement and reach peak sustainability.

Replacing an air filter too early wastes money—but waiting too long quietly drives up energy bills as your HVAC works harder through a clogged filter. In this guide, we break down how to find the “sweet spot” by weighing efficiency loss, filter cost, and labor. We also introduce an IoT-based calculator powered by real-time readings from the Ellenex PDT2 Differential Pressure Sensor, helping you know when to order a new filter and when it’s time to schedule maintenance.

Data centers live and die by airflow. When server racks lose positive pressure, cooling becomes less efficient, contaminants can creep in, and fans work harder—raising risk and operating cost. In this customer story, Ellenex shows how positive pressure monitoring delivers near real-time visibility into rack health, enabling predictive maintenance and smarter interventions before issues turn into outages. Using the PDT2-L differential pressure sensor (with temperature), operat
