PLATINUM TEMPERATURE PROBE 4-20mA OUTPUT

INSTRUCTION SHEET 41342L-90

REV 9-97

INTRODUCTION

The Model 41342LC/LF Platinum Temperature Probe is an accurate 1000
ohm Platinum RTD temperature sensor and 4-20 mA line driver interface
mounted in a weatherproof junction box. The probe is available in
Celsius or Fahrenheit calibration. 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. YOUNG naturally ventilated or motor
aspirated shields are recommended. 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 nominal cost.
