Overview

GTHD digital sensorThe GTHD digital sensor collects and transmits real-time temperature, humidity and dew point data to protect critical data center equipment from heat and moisture. The GTHD model offers two RJ12 ports, an uplink port to connect to a host device and a supplementary input for daisy-chaining.

The GTHD requires a host device to transmit data. It counts as a single digital sensor while reporting multiple temperature readings. The unit may be daisy chained with other GTHD or GT3HD sensors to form a sophisticated climate monitoring network with real-time data logging and alarming. This is especially useful when achieving in-row temperature monitoring for top, middle, and bottom of each rack as per ASHRAE guidelines. The plastic enclosure mounts easily anywhere in the data center with screws, magnets or adhesive.

Each GTHD comes standard with a 10’ uplink cord (50’ cord is optional).

Sensor Details
Temperature Range
-4 °F to 176 °F (-20 °C to 80 °C) +/-0.5 °C
Humidity: 5% to 95%, +/-3%
Dew point: -58 °F to 185 °F (-50 °C to 85 °C)

Overview

GT3HDThe GT3HD digital sensor collects and transmits real-time temperature, humidity and dew point data to protect critical data center equipment from heat and moisture.

The GT3HD model offers four RJ12 ports to connect two remote temperature (SRT) sensors, one uplink to connect to a host device and a supplementary input for daisy-chaining. The unit comes equipped with a 3' and 6' temperature sensor to monitor locations within the server rack. 

The GT3HD requires a host device to transmit data. It counts as a single digital sensor while reporting multiple temperature readings.

Overview

Geist Analog to Digital ConverterThe Analog to Digital converters, better known as the A2D, converts an analog sensor into a digital sensor that can be connected to a digital sensor port on a PDU or Watchdog 15/100 environment monitor. Useful for adding additional analog sensors when all of your existing analog inputs are already used up with other sensors. It is compatible with Geist sensors as well as any industry standard sensors that are dry-contact or that emit a 0-10VDC or 4-20mA signal.

RTAFHD3

Temperature, Airflow, Humidity, and Dew Point Sensor

Tabs

Overview

Remote Temperature, Airflow, Humidity and Dew Point (RTAFHD3) SensorThe Remote Temperature, Airflow, Humidity, and Dew Point (RTAFHD3) sensor provides real-time values and feeds data back to the unit for data logging and alarming. All sensors are instant plug and play with standard RJ-12 jacks. Monitor temperature and humidity to identify hot spots, and adjust the ambient temperature of your data center to reduce cooling power consumption while increasing efficiency within ASHRAE guidelines.

Sensor Details: Accurate to +/-0.5° C within the normal operating range of 5° C to 60° C; Accurate to +/-2% RH within the normal operating range of 20% to 80% RH at 25° C; maximum operating range of -40° C to 85° C (-40° F to 185° F)
Note: The maximum combined cable length for digital sensors is 600 feet.

Overview

SRTWatchdog digital sensors communicate with climate monitors through a digital serial bus. On those units that support digital sensors - up to 16 can be added by using splitters. The monitor auto detects the sensor type and identifies it on the web interface. Each digital sensor has a friendly name that can be set by the user. Sensors are available in several different lengths, however the total cable length of all digital sensors combined should not exceed 600'.

Sensor Details: Temperature: -55°C to +125°C (-67°F to +257°F)
Accuracy: +/-0.5°C accuracy from -10°C to +85°Ch
