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.
