The Power-over-Ethernet (PoE) High Temperature Sensor uses a glass coated platinum RTD transducer to accurately measure temperatures from -50°C to +370°C (-58°F to +700°F). The High Temperature Sensor outputs the ambient temperature in degrees Celsius or Fahrenheit and alerts the user when a temperature threshold is crossed.
The Power-over-Ethernet (PoE) Sensor products measure various conditions (environmental, power, access). All devices come with flexible settings — including notifications, alerts, reports, and maps — can be customized in the iMonnit online sensor management interface.
No PoE infrastructure in your building? Plug the PoE•X Sensors into your Ethernet network and then power the sensors with the optional AC power supply.
