SENSORS

General Description

The HydroLynx relative humidity and temperature sensors are designed for use in meteorological monitoring stations. Model 2048RH/T has both relative humidity and air temperature in a single probe. Model 2046T is a temperature only sensors for monitoring air. The air sensors are mounted in the Model 4550 Solar Radiation Shield.

The 2048RH/T combines microprocessor technology for accurate linearization of both sensors over the entire range of measurement with an advanced humidity sensor that exhibits exceptional resistance to contaminants providing accuracy and durability for a wide range of applications.

The 2046T sensor uses an integrated circuit transducer that provides a linear output current proportional to the absolute temperature. A signal conditioning board calibrates the measured temperature range over a 0-5 Vdc output.
