Hx-68P3 Series Outside Humidity and Temperature Transmitters

The Hx-68P3 Series Outside Humidity and Temperature Transmitter measures and transmits outside relative humidity (RH) from 0 to 100% and temperatures from -40 to 140F (-40 to 60C). In addition to RH, the transmitter offers selectable parameters including dew point, wet bulb temperature, and enthalpy. The humidity sensor is impervious to dust and most chemicals and is not damaged by condensation. The weather shield protects the sensors from solar radiation and precipitation without affecting performance. The multiple discs have a unique profile that permits easy passage of air. The disc material is especially formulated for high reflectivity, low thermal conductivity and maximum weather resistance. This rugged enclosure will assure a long life, even under extreme weather conditions. The sensor and shield function as one unit for optimal performance. Mount the transmitter outside on a pole or on a side of a building. It requires no routine maintenance or recalibration.

Features
• 0 to 100% RH offers a full range of accurate RH measurement
• rugged shield construction protects sensors from solar radiation and precipitation without affecting performance
• multiplate shield design maximizes airflow for precise RH and temperature readings
• excellent long-term stability provides accurate RH measurement over long periods of time without degeneration
• no routine maintenance or calibration ensures low maintenance cost
• two wire loop powered connection 4 to 20 mA or four wire 0 to 10 VDC looped power-output enables easy installation
• polymer thin film sensor omits inaccuracies due to dust, water vapor, harsh environments or most chemicals
• negligible temperature coefficient ensures that temperature changes are immaterial to accurate RH measurement
