Tính năng sản phẩm

The Series RHP Humidity/Temperature Transmitters combine the voltage or
current humidity transmitter output with a passive temperature thermistor or RTD
output. Featuring polymer capacitance humidity sensors, models are available with
2%, 3% or 5% accuracies. Duct mounted transmitters are available with an optional
two-line alpha numeric LCD display.
BENEFITS/FEATURES
• Reduced installation cost with combined humidity and temperature
• Wide application environment from a large selection of temperature sensors and 2%,
3% and 5% accuracies
• Reduced system operating costs with radiation shield protecting the sensor from
radiant heat
APPLICATIONS
• Air economizers
• Outdoor temperature and relative humidity reference
• Pool room humidity monitoring
