Wet/Dry Bulb Transducers

Wet/Dry Bulb Transducers

The HT-WD-420 provides inexpensive yet very accurate rH measurements over a wide temperature range. It connects to two RTD sensors in a wet/dry bulb arrangement and outputs 4-20mA proportional to 0-100% rH. The board may be used for rH measurements in industrial environment where high temperatures and harsh environment preclude the use of other instruments.
