INTRODUCTION
The Model 41382VC/VF Relative Humidity/Temperature Probe com-
bines a high accuracy humidity sensor and temperature sensor in one
probe. The probe is available in Celsius or Fahrenheit calibration.
Output signal is 0-1V for both Relative Humidity and Temperature.
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. Recalibration will
restore probe to acceptable limits.
In areas of high dust or contamination (ie: smokestacks, seawater),
periodic cleaning of the RH sensor protective filter is recommended.
Soaking in clean water or a mild soap solution is recommended. DO
NOT USE SOLVENTS.
CE COMPLIANCE
This product has been tested and shown to comply with European CE
requirements for the EMC Directive. Please note that shielded cable
must be used.
