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.
NCD builds three wireless pressure sensors, and they differ in exactly one thing: the pressure they are built to read. Pick by the size of the number you expect to see.
Pair the sensor with an Atrium Gateway, open a browser on your network, and drag the readings you care about onto a dashboard. No code to write.
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, in gas, liquid or vapor service, from chemical plants and food lines to power stations.
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.
Wellheads & SeparatorsWatch wellhead, separator and pipeline pressure at field sites without running power or signal wire.
Irrigation & Spray SystemsTrack irrigation, pump and spray-system pressure across remote farm operations.
Mining Hydraulics & DewateringMonitor hydraulic and dewatering-pump pressure on heavy equipment in harsh, remote conditions.
The math is simple. One purchase versus compounding monthly fees.
Pressure shows what the line is doing. These sensors cover the pump and the tank around it, on the same Atrium gateway.
Smart Vibration SensorMount it on the pump motor. A failing bearing shows up in vibration weeks before the pressure drops.
AC Current MonitorClamp the CT on the pump circuit. Current draw shows whether the pump is running and how hard it is working.
Tank Level SensorMount it at the top of the tank the pump draws from. Level and line pressure sit on one dashboard.
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.
We publish our prices. There is no quote form, no login and no sales call between you and the number. The Ordering section of the spec table names each version we sell and its part number, so you can match the one you want before you order.
The wetted part is a 316L stainless steel diaphragm, so the media has to be compatible with 316L: gas, liquid or vapor that will not attack stainless. Media that corrodes stainless needs a different sensor. Tell us what is in the line and we will confirm whether this one suits it.
Our engineers answer in public on the community forum, and the thread stays up for the next person with the same question.
