6.2.5 Virtual Sensors

The Synergy Controller supports a variety of Virtual Sensor for a variety of applications. The virtual accepts
on or more sensors and calculates a new sensor value.
6.2.5.1 Wet Bulb/Dry Bulb Virtual Sensor
The Virtual Wet Bulb/Dry Bulb sensor measures relative humidity using two temperature sensors as an
alternative to an electronic RH sensor. To make these measurements, a wet-bulb sensor infers the amount
of moisture in the air when the evaporation from a moist cloth wick placed over the sensor lowers its
temperature reading. When the air surrounding the wet-bulb sensor is dry, evaporation of moisture from the
wick is faster than when the air is moist. If the air is saturated, no evaporation from the wick occurs and the
temperature of the wet-bulb sensor is the same as the temperature of the dry-bulb sensor.
The Wet Bulb/Dry Bulb Virtual Sensor folder includes all of the parameters that configure the sensor.
