• Capacitance polymer humidity sensor for long-term stability and reliability
• Duct mount configuration with plenum plastic probe and hydrophobic filter
• Selectable analog output: 4-20 mA, 0-5 VDC, or 0-10 VDC (field selectable)
• Small enclosure design with IP66 environmental rating
• Temperature measurement with solid state band gap sensor technology
• Optional calculations for absolute humidity, dew point, and enthalpy
• UL 2043 compliant for plenum space installation
• Power requirements: Analog model requires 10-35 VDC or 15-35 VDC/15-29 VAC depending on output type

The Series RHPX transmitter accurately monitors humidity and temperature for building control functions to maximize occupant comfort and minimize operating costs. With its high accuracy and reliable operation, this transmitter is ideal for building energy management systems, commercial HVAC applications, clean rooms, museums, and data centers where precise environmental monitoring is critical.
