Temperature and Humidity Sensor The SMC SMC-520 is designed for high demanding outdoor applications for temperature and humidity measurement. The SMC-520 delivers a reliable and accurate readings for various meteorology applications. Function 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 instruments internal processor and output over a serial communication port. Key Features Operational range -40 to +60° Celsius 0.2° Celsius Accuracy 1.5% Humidity Accuracy Excellent Long term Stability Serial NMEA Communication 2 years Warranty Environmental The SMC-520 casing is produced out of UV resistant ABS plastic material. The temperature and humidity sensor is delivered with a sintered Teflon filter to protect the sensing elements from water, dust and dirt. The SMC-520 is IP66 rated. About SMC SMC is an ISO9001:2015 quality management certified company, manufacturing weather instruments, motion sensors and system integration software packages, such as Helideck Monitoring and Motion Monitoring systems, for the global marine industry. Communication The SMC-520 have RS232 and RS485 outputs and is transmitting its data in a standard ASCII string. The temperature and humidity string is easily integrated to dataloggers and display software available on the market. Calibration 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. Offset adjustments to the temperature and humidity measurement can be made onsite using the instrument configuration software.
