Remote Boiler Monitoring System
Remotely monitor temperature, pressure, and water leaks for industrial/commercial boilers. Identify boiler room issues before they become major problems.
Overview
ControlByWeb® products can help you with your boiler monitoring system and avoid potential, costly damage. Remotely monitor temperature, pressure, and water leaks for industrial/commercial boilers.
Connect any ControlByWeb temperature monitoring device to a local area network to access the built-in control and setup web pages using a standard web browser. No additional software or cloud services are needed.
Boiler Monitoring Example
In this example, an X-420 is connected to three sensors to monitor the pressure and temperature of an industrial boiler, as well as to detect water leaks.
Features
- Email Notifications
- Logging & Graphing
- Built-In Web Server (For Local & Remote Access)
- Monitor Sensors Such as:
- Temperature Sensors
- Pressure Sensors
- Water Leak Sensors
- Carbon Monoxide Sensors
- AC Current Sensors

X-420 used for remotely monitoring a boiler's temperature, pressure, and water leaks.
*The above illustration is for demonstration purposes only, it does not represent actual wiring and is not to scale.
Boiler Pressure Monitoring
Monitor boiler pressure with a compatible pressure sensor installed in a boiler and connect it to an analog input on a ControlByWeb device to watch for pressure spikes or drops.
Boiler Temperature Monitoring
Connect a digital temperature sensor via 1-Wire Bus to monitor boiler supply and return line temperature. Monitor and graph temperature data over time on the ControlByWeb device. For high-temperature monitoring we recommend using an isolated thermocouple with a thermocouple to 1-Wire adapter.
Water Leak Detection
Place a water sensor near your boiler and attach it to a digital input on a ControlByWeb module to detect water leaks.
Custom Email/Text Alerts
Set email alerts based on custom high/low thresholds for temperature, pressure, and water leak sensors.
