The TCAV-L typically provides the average temperature of the top 6 to 8 cm of soil for energy-balance in flux systems. It parallels four thermocouples together into one 24 AWG wire. Each member of a thermocouple pair can then be buried at a different depth. The two pairs are separated at a distance of up to 1 m.Read More

Yes, as long as the TCAV-L is measured using a differential measurement instruction. Be sure to connect the shield wire to analog ground.
The TCAV-L measurement range, accuracy, and resolution are a function of the data logger used to measure the TCAV-L. Refer to the appropriate data logger manual measurement section for more information.
The TCAV-L is constructed using a Type E thermocouple wire. The high-order NIST polynomials were fit over the temperature range of -270° to 1000°C. The temperature range of a TCAV-L on a data logger depends on the measurement range selected in the thermocouple measurement instruction. For example, using a CR3000 and the ±20 mV input range and a reference temperature at 20°C, the TCAV-L temperature range is -270° to 300°C. Refer to the measurement section in the appropriate data logger manual for a detailed discussion on thermocouple measurements.
The TCAV-L is a Type E thermocouple. Use a Type E (chromel –constantan) Thermocouple found in the Sensor | Temperature group.
