INTRODUCTION

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 lter 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.
