Ellenex PLM2-N: Submersible Miniature Level Sensor for Underground Water bore monitoring. Modern LPWAN technologies ensure longevity and compatibility with future infrastructure. The choice between cellular (PLM2-N) and LoRaWAN (PLM2-L) depends on the specific operational requirements and existing infrastructure.

Traditional wastewater monitoring is often reactive, leading to costly overflows and environmental hazards. By harnessing IoT-integrated sensors, municipalities can now transition to a proactive stance. These smart systems provide real-time data on manhole and wastewater levels, enabling teams to detect blockages or surge events before they escalate. With long-range connectivity and low-power consumption, IoT is transforming aging infrastructure into a responsive, digital net

LPWAN technologies such as LoRaWAN, NB-IoT, and LTE-M are transforming industrial monitoring by making large-scale IoT sensor networks practical, scalable, and cost-effective. This article explains how LPWAN supports long-range connectivity, low power consumption, and wide-area deployment for water infrastructure, HVAC, utilities, and remote industrial assets.

Executive summary Differential pressure (ΔP) measurement sits at the intersection of energy, IAQ, compliance, and reliability in HVAC. It’s used for filter loading, duct static pressure, airflow inference, fan performance, and room pressurization (cleanrooms / isolation rooms). Three types of sensor dominate the market: Mechanical gauges : lowest cost and simplest deployment, but usually local-only visibility unless you add switches or manual rounds. Wired electronic transm

Groundwater is a vital but depleting resource. Monitoring 2-inch wells has long been a challenge due to size and cost constraints. Ellenex introduces the PLM2 series—the 'Tiny Tech Titan.' With a 15.8mm sensor head, it fits narrow wells perfectly. Available in PLM2-N and PLM2-L, it offers 40% lower costs than alternatives. From aquifers in Germany to sites in Canada, these sensors deliver real-time data for precision water stewardship.

Ensure safety and regulatory compliance in medical, pharmaceutical, and aerospace sectors with LoRaWAN® and NB-IoT differential pressure monitoring. This technical guide examines how the Ellenex PDT2 series manages positive and negative pressure environments to prevent contamination and infection spread. Discover the advantages of LPWAN-based condition monitoring for HVAC filters, hospital isolation rooms, and ISO-rated cleanrooms, featuring high-precision data for audit-read

Choosing the right differential pressure sensor can significantly impact accuracy, efficiency, and long-term operating costs. This article compares the modern, wireless Ellenex PDT2 with the traditional Dwyer Magnehelic gauge, highlighting key differences in precision, data integration, installation, and scalability. While the Magnehelic remains a reliable mechanical option for simple visual monitoring, the PDT2 stands out with high accuracy, low-power operation, and seamless

Replacing AHU filters on a fixed schedule is simple—but it often wastes money or misses the moment performance starts to drop. Wireless differential pressure sensors solve this by continuously measuring the pressure drop across the filter, revealing clogging trends, efficiency losses, and the true end-of-life point. In this guide, we cover how differential pressure data supports condition-based maintenance, reduces energy waste, and improves indoor air quality—while enabling
