RELATIVE HUMIDITY/TEMPERATURE PROBE w/4-20mA OUTPUT
INTRODUCTION
The Model 41382LF2 Relative Humidity/Temperature Probe combines
high accuracy humidity and temperature sensors in a single probe. The
output signal is 4-20 mA. RH range is 0-100%. Temperature range is
-50 to +150°F.
INSTALLATION
The Relative Humidity/Temperature probe should always be installed in
a protective radiation shield to ensure accurate data. Use of the probe
without a radiation shield may result in large errors. The probe installs
easily in YOUNG naturally ventilated or motor aspirated shields. For
best performance, the probe and shield should be placed in a location
with good air circulation clear of large masses (buildings, pavement,
solar panels...), Exhaust vents, electrical machinery and motors, water
fountains and sprinklers.
MAINTENANCE
The Relative Humidity/Temperature probe is designed to offer years
of service with minimal maintenance. As with most humidity sensors,
humidity calibration may drift slightly with time, and can be checked
or restored at the factory. Periodically clean the humidity sensor lter
when used in areas of high dust or contamination (smokestacks,
seawater, etc.) Remove from sensor and soak in clean water or use
a mild soap solution. DO NOT USE SOLVENTS.
WARRANTY
This product is warranted to be free of defects in materials and
construction for a period of 12 months from date of initial purchase.
Liability is limited to repair or replacement of defective item. A copy
of the warranty policy may be obtained from R. M. Young Company.
