Temperature and Humidity sensor SMC-520

Application

Calibration

Specifications

The SMC-520 is designed for high demanding outdoor applications for temperature and humidity measurement. It delivers a reliable and accurate readings for various meteorology applications.

The SMC-520 uses a high grade PT1000 element for the temperature measurement and a capacitive humidity sensor with excellent long-term drift performance. Data is processed within the instrument’s internal processor and output over serial RS232 and RS485 communication ports.

The SMC temperature sensor is factory calibrated for the range -40 to +60 degrees Celsius. The humidity sensor is adjusted for both temperature and humidity level parameters to deliver accurate data. SMC uses a multiple point calibration to cover the specified temperature and humidity range.
