Made in the USA
No software to install. No cloud accounts to create. Wire your probe, power on, monitor.
Wire an RTD probe to the channel — PT100 3-wire is standard, with PT1000 and 2-/4-wire supported on request. A sample PT100 probe is included to get started right out of the box.
Wall-mount or magnet-mount the enclosure. Run it on a D-cell with Supercap or the external-power option. The IP65 enclosure handles harsh, washdown environments.
900MHz self-forming wireless mesh network. Up to 2-mile line-of-sight range with multi-hop routing across your facility.
Browser dashboards, threshold email alerts, and CSV export. Forward readings to AWS, Azure, or any MQTT broker. Catch temperature excursions early.
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 RTD sensors at it, open your browser, and go, your data stays on your network.
Drag-and-drop widgets let you build custom temperature-monitoring views for any audience, operators on the floor, maintenance managers, or quality teams. Every dashboard auto-refreshes and supports fullscreen mode for wall-mounted displays.
Configure threshold-based triggers on the temperature channel. When a reading crosses your limit, Atrium fires email notifications, logs the event, and can actuate relay outputs to start backup cooling or sound alarms, all without writing a single line of code.

Answers to the most common questions about wireless RTD temperature monitoring.
The Industrial IoT Wireless RTD Temperature Sensor from NCD is a battery-powered industrial sensor that measures temperature on a single RTD channel and transmits readings wirelessly up to 2 miles. It supports PT100 and PT1000 probes in 2-, 3-, and 4-wire configurations, runs for years on a D-cell with Supercap, and carries no monthly fees or subscriptions.
Accuracy depends on the RTD probe you connect. The transmitter itself resolves fine temperature changes, and the included PT100 is a sample for experimentation only. For production accuracy, pair the Industrial IoT Wireless RTD Temperature Sensor with an RTD probe rated for your process.
It works with PT100 RTD probes in the standard 3-wire configuration, and supports PT1000 and 2-/4-wire RTDs on request. The Industrial IoT Wireless RTD Temperature Sensor ships with a sample PT100 probe for experimentation, so you can start taking readings right out of the box.
The measurable range depends entirely on the RTD probe you connect — there is no fixed range built into the transmitter. The included PT100 is a sample for experimentation; for production, connect an RTD probe rated for your process temperatures and the Industrial IoT Wireless RTD Temperature Sensor will report across that probe’s range.
The sensor reaches up to 2 miles line-of-sight using 900MHz long-range wireless mesh networking (about 1000 ft in dense urban environments). Because the Industrial IoT Wireless RTD Temperature Sensor forms a self-healing mesh, a single Atrium gateway can collect readings from many sensors across large or multi-building facilities.
Battery life depends on how often it transmits. The Industrial IoT Wireless RTD Temperature Sensor runs up to 5 years on a D-cell with Supercap. An external-power option is also available for continuous-duty installations.
No. The Industrial IoT Wireless RTD Temperature Sensor has no monthly fees and no proprietary lock-in. You own your data and can keep it on your own network or forward it to AWS, Azure, or any MQTT broker through the Atrium gateway, there are no recurring software costs.
Yes. Readings from the Industrial IoT Wireless RTD Temperature Sensor flow through the Atrium gateway, which supports AWS, Azure, MQTT, Modbus, Node-RED, and a REST API. Data is encrypted with 128-bit AES in transit, and you can route it into existing SCADA, CMMS, or analytics platforms without vendor lock-in.
Yes. The Industrial IoT Wireless RTD Temperature Sensor uses an IP65 main enclosure (rated on the box only, not the probe) also rated to NEMA 1/2/4/4X/12/13 and UL-508, with wall-mount or magnet-mount options. It is built to handle dust, washdown, and harsh plant-floor conditions.
The Industrial IoT Wireless RTD Temperature Sensor is made in the USA and is RoHS compliant. Its 900MHz wireless module carries CE/RED certification, and additional regional certifications (FCC, IC, RCM, Anatel, and more) are available depending on the frequency band, so it can be deployed across many regions.
One purchase. Full ownership. Industrial-grade RTD temperature monitoring that pays for itself.
