INTRODUCTION
The Model 41342 Platinum Temperature Probe is an accurate 1000
ohm Platinum RTD temperature sensor mounted in a weatherproof
junction box. The probe is designed for easy installation in YOUNG
Multi-plate and Aspirated Radiation Shields.
INSTALLATION
For accurate measurements, the temperature probe should be installed
in a protective radiation shield. Use of the probe without a radiation
shield may result in large errors due to solar heating. The probe installs
easily in YOUNG naturally ventilated or 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, motors, water
fountains and sprinklers
MAINTENANCE
The temperature probe is designed to offer years of service with minimal
maintenance. If necessary, the probe may be periodically checked or
recalibrated using normal bath calibration methods. NIST traceable
calibration is available from YOUNG at additional cost.
NOTE: The terminal marked "EARTH GND" should be connected
to properly grounded tower or grounding conductor as close to the
sensor as possible. Failure to do so may result in damage due to
static discharge.
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.
