MODEL 41342
PLATINUM TEMPERATURE PROBE
INSTRUCTION SHEET 41342-90
REV: C111215
INTRODUCTION
The Model 41342 Platinum Temperature Probe is an accurate 1000
ohm Platinum temperature sensor mounted in a weatherproof junction
box. The sensor output uses a 4 wire RTD conguration. 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.
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.
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.
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.
CE COMPLIANCE
This product has been tested and complies with European CE
Requirements for the EMC Directive. Please note that shielded cable
must be used.
EMC COMPLIANCE
This device complies with Part 15 of the FCC Rules. Operation is
subject to the following two conditions: (1) this device may not cause
harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.
This equipment has been tested and found to comply with the limits
for a Class A digital device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with
the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area
is likely to cause harmful interference in which case the user will be
required to correct the interference at his own expense.
This ISM device complies with Canadian ICES-001.
Cet appareil ISM est conforme à Ia norme NMB-001 du Canada.
EN55011/CISPR 11, Group 1, Class B device.
Class B equipment is suitable for use in domestic establishments and
in establishments directly connected to a low voltage power supply
network which supplies buildings used for domestic purposes.
