about the temperature probe
The external temperature sensor adds an additional monitoring point to the SensorGateway, the base unit. For example by using 2 external temperature probes you can monitor with one single device temperature in 3 different points. This ideal to monitor one rack: front top and bottom. When using floor cooling you will get front the bottom front temperature sensor the temperature of the air getting to the rack. The top front sensor will inform you if sufficient cool air gets to the top of the rack. The hottest point in a rack is the top back of the rack, as hot air climbs. The delta between intake and outtake temperature may not exceed 20°C or 34°F.

The sensor can monitor temperature in degrees Celsius or Fahrenheit within a range of -55C to +125C (-67F to +167F). It has a precision of 0.1C (0.18F) with an accuracy of 0.5C (0.9F) from -10C to +85C / 14F to 185F. Please consider that the SensorGateway has different operating temperature ranges.

Sensor Drifting & Calibration.
Fact is that all sensors do drift over time mainly due to physical factors.

Our temperature sensors are tested in the factory for tolerance prior to shipping to you. Customers requiring calibration certificates for compliancy or assurance purposes can request a calibration certificate from our in-house lab with their purchase. It is recommended to have your temperature sensor calibrated at least once per year.

Daisy Chain Option Available
Illustration showing the operation of the InfraSensing daisy chained temperature sensor
Need to connect multiple temperature sensors? A base unit supports up to 8 sensors to be connected with the optional Sensor Hub. If you need more than 8, then our daisy chain version of the sensor allows you to connect up to 20 temperature sensors to one base unit.
