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 -55°C to +125°C (-67ºF to +167ºF). It has a precision of ±0.1ºC (0.18ºF) with an accuracy of ±0.5°C (0.9°F) from -10°C to +85°C / 14°F to 185°F. Please consider that the SensorGateway has different operating temperature ranges.
