I NTRODUCTION
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
Install the probe in a naturally ventilated or fan aspirated radiation
shield. Mount probe and shield in a location with good air
circulation clear of large thermal masses (buildings, pavement,
solar panels, etc.), exhaust vents, electrical machinery and motors,
water fountains and sprinklers. Typical wiring diagrams appear on
next page.
MAINTENANCE
The probe provides years of service with minimal maintenance.
Humidity calibration, which may drift slightly with time, can be
checked or restored at the factory.
Periodically clean the humidity sensor filter when used in areas of
high dust or contamination (smokestacks, seawater, etc.) Soak in
clean water or use a mild soap solution. DO NOT USE SOLVENTS.
CE COMPLIANCE
This product complies with the European CE directive on EMC
compatibility. Shielded cable must be used.
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.
