Note: the entire kit counts as a single digital sensor to the host device. The T3HD may be daisy chained from one rack to the next to achieve in-row temperature monitoring for the top, middle and bottom of each rack (see img2) as per ASHRAE guidelines.
Like the Temperature, Humidity, Dew Point Sensor (THD
), the T3HD provides real-time measurements to the host device for data logging and alarming. A 6P6C modular patch cable for connection from sensor to host device is included (please select desired length from dropdown). The sensor mounts nearly anywhere using screws or adhesive.
The T3HD is especially useful for watching out for rapid temperature drops and/or high humidity that can cause condensation to form on electronic equipment, resulting in hardware corrosion and component failure. Electrostatic discharge is likely to occur at low relative humidity levels, which can severely damage sensitive IT equipment. Based on ASHRAE’s recommended humidity range for IT equipment, we suggest setting relative humidity alarm thresholds for when the value exceeds 55% or falls below 40%; however, each facility is unique and may require varied ranges.
Note: The T3HD requires a Watchdog 1200 monitor with v3.9.4 firmware or higher, or a Watchdog-series device with v1.4.0 firmware or higher, and at least one available digital sensor bus jack. The older WxGoos Series I monitors (any model with a v2.xx firmware) do not support the T3HD.
