The ASPTC is a type E thermocouple housed in a white, elongated radiation shield. The radiation shield reduces solar loading on the thermocouple by drawing air across the measurement junction with a fan. The radiation shield also protects the thermocouple, increasing its durability.
Typically, one ASPTC is mounted to each sensor arm in a Bowen ratio system. One ASPTC 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.
The ASPTC-L is a Type-E thermocouple and aspirated shield that provides accurate air temperature measurements. The sensor is housed in a white, elongated radiation shield that reduces solar loading on the thermocouple by drawing air across the measurement junction with a fan. The radiation shield also protects the thermocouple, increasing its durability. The ASPTC-L easily interfaces to most Campbell Scientific dataloggers.
One ASPTC can measure absolute air temperature, or two ASPTCs can make delta temperaturemeasureme
