General Description

The ASPTC-L is a white, elongated radiation shield that reduces solar loading on a thermocouple by drawing air across the measurement junction with a fan. The radiation shield also protects the sensor, increasing its durability. Typically, one ASPTC-L is mounted to each sensor arm in a Bowen ratio system. One ASPTC-L can either replace, or be measured in addition to, TCBR thermocouples. In a standard configuration, lead lengths of 15 feet are recommended for both signal and power cables.
