Made in the USA
No software to install. No cloud accounts to create. Thread it in, power on, monitor.
Thread the industry-standard 1/4" NPT male connector into your line, tank, or manifold, no special adapters and no wiring to run.
Run on a D-cell with supercapacitor or the external 5–12 V DC power option. The IP65 enclosure handles dust and washdown environments.
Readings hop sensor-to-sensor across a wireless mesh, so one gateway covers a large plant or a spread-out site without new cabling.
Watch live pressure on browser dashboards, get threshold email alerts, and export to CSV, or forward readings into the cloud, historian, or SCADA you already run.
The Atrium Gateway isn’t just a data receiver. It’s a complete industrial IoT platform with dashboards, alerts, reporting, and built-in apps. Point your pressure sensors at it, open your browser, and go.
Drag-and-drop widgets let you build custom pressure-monitoring views for any audience, operators on the floor, maintenance managers, or process engineers. Every dashboard auto-refreshes and supports fullscreen mode for wall-mounted displays.
Configure threshold-based triggers on pressure or battery. When a reading crosses your limit, Atrium fires email notifications, logs the event, and can actuate relay outputs to stop a pump or sound an alarm, all without writing a single line of code.

Atrium works as a fully self-contained system, but when you need to integrate, Node-RED is built in and ready. Push data to cloud platforms, databases, SCADA systems, or custom APIs, all configured through a visual flow editor.
Rugged pressure monitoring designed to run for years and be read from anywhere on site.
Choose the pressure range you need, from 0–20 psi up to 0–10,000 psi. One sensor family covers everything from low-pressure air to high-pressure hydraulics.
±0.5% full-scale pressure accuracy with ±0.3% FS/year long-term stability, plus on-board temperature to ±1.5°C, readings you can trust over the life of the deployment.
An OEM piezoresistive sensor with a 316L stainless-steel corrugated diaphragm and isolated oil-fill construction reads your process media directly at the port — compressed air, liquids, and vapor compatible with 316L stainless, no separate transmitter.
A built-in retry re-sends any packet lost to RF noise, so a busy plant floor never leaves gaps in your pressure trend.
Runs up to 5 years on a D-cell with supercapacitor, with real-time battery-status reporting. An external 5–12 V DC power option is also available.
Update firmware wirelessly across your fleet over the wireless mesh network. No climbing ladders, no removing sensors from service.

Anywhere a pressure needs to be watched continuously and wirelessly.
Hydraulic & Pneumatic SystemsMonitor working pressure on presses, actuators, and power units to catch seal wear and pump fade before a line goes down.
HVAC & RefrigerationMonitor refrigerant-line and compressor pressure in HVAC and refrigeration systems, so a slow refrigerant leak or a struggling compressor shows up as a pressure trend before cooling drops off.
Pump & Filter HealthWatch discharge and differential pressure to see a clogging filter or a cavitating pump as a trend, not a surprise failure.
Tank & Vessel PressureHigher-range sensors suit sealed tanks, autoclaves, and pressurized vessels, and bottom-mounted pressure tracks the fill level inside.
Boiler & Steam SystemsRegulate and watch pressure on industrial boilers and steam lines, keeping operators clear of hot, hazardous areas while the pressure reports back to the control room in real time.
Water & Wastewater SystemsMonitor line, lift-station, and filter pressure across treatment sites and remote pump stations miles apart.

Answers to the most common questions about wireless pressure monitoring.
It’s a battery-powered industrial sensor that reads pressure through a 1/4" NPT connection and sends the data wirelessly to a gateway. You get ±0.5% full-scale accuracy, on-board temperature, wide media compatibility, and years of battery life, with no monthly fees.
Pick the range that brackets your working pressure with some headroom, options span low-pressure air up to high-pressure hydraulics. Sizing the range to your process keeps the ±0.5% full-scale accuracy meaningful, since accuracy is a percentage of the full range.
No. This sensor is not rated for vacuum or sustained negative pressure, long-term exposure can damage the sensing element. If you need to measure below atmospheric or in both directions, NCD builds a dedicated wireless differential-pressure sensor with the right element for that job; talk to an engineer and we’ll point you to it.
Ranges run from 0–20 psi up to 0–10,000 psi, selected by variant, at ±0.5% full-scale accuracy with ±0.3% FS/year long-term stability, so each unit holds its calibration across long deployments.
Each sensor sends readings to a gateway over a long-range wireless link, up to 2 miles line-of-sight (about 1000 ft in dense urban areas). Sensors relay through a mesh, so one gateway collects from many sensors across a large or multi-building site.
Just the sensor and one gateway. A single gateway talks to many sensors at once, so you add sensors without adding infrastructure. Wi-Fi isn’t required, though a Wi-Fi/MQTT gateway is an option if you have it, and cellular gateways cover remote sites with no local network.
Up to 5 years on a D-cell with supercapacitor, with battery status reported in real time. External-power variants (5–12 V DC) are available for permanent installations.
None. There are no subscriptions and no per-device software fees, you buy the hardware once and own it outright, along with all of your data. No contracts, no proprietary lock-in.
Yes. Through the Atrium gateway, readings can go to AWS, Azure, MQTT, Modbus, Node-RED, or a REST API, and into existing SCADA, CMMS, or analytics platforms. Data is AES-128 encrypted in transit.
Yes. The main enclosure is IP65 rated (the box only, not the pressure port) and also meets NEMA 1/2/4/4X/12/13 and UL-508, built for dust, washdown, and harsh plant-floor conditions.
Made in the USA and RoHS compliant. The 900 MHz wireless module carries FCC (USA), IC (Canada), C-Tick (Australia), Anatel (Brazil), IDA (Singapore), and CE/RED certifications for deployment across many regions.
One purchase. Full ownership. Industrial-grade pressure monitoring that pays for itself.
