The 597 is an integrated Temperature, Relative Humidity and Pressure measurement sensor. All sensing elements are of the highest quality and are specifically designed for continuous duty in hostile environments. The temperature sensor utilises platinum RTD class 1/3B. Relative Humidity is a based on our very accurate solid-state sensor design for continuous exposure to adverse climates, and the Barometric Pressure sensor is a piezo-resistive device designed for robustness, high accuracy and long-term stability.
All components are housed in a Multi-Plate naturally aspirated Radiation shield to reduce solar radiation heating errors. The shield consists of a series of white aluminium concentric plates, which allow air flow to pass through the shield, while blocking direct solar rays.
The 597 has both analog and digital outputs for maximum flexibility with additional connectivity options are available with the optional 10600 Interface. Analog outputs provide conventional connections to data loggers and systems utilising a voltage proportional to each of the three measurements.
Digital outputs are available as a serial data stream every second, or upon command by the data system. The digital outputs offer higher resolution and immunity to analog offset problems.
