In Dynamax’s continuing efforts to improve our sap flow technologies, we introduce the SGDC sap flow sensor. This new sensor requires only (2) data logger channels, which allows for twice as many sensors to be connected to the data logger. The basic principles of operation for the SGDC are the same as the tried and proven heat balance method used by our other sap flow sensors.

The Thermal Dissipation Probe (TDP) transpiration sensor measures sap velocity which is converted to volumetric flow rate. TDP is a simple and affordable device originally proposed by Granier. The basic TDP probe has two thermocouple needles inserted in the sapwood, the upper one containing an electric heater. The probe needles measure the temperature difference (dT) between the heated needle and the sapwood ambient temperature below. The dT variable and the maximum dTm at zero flow provide a direct conversion to sap velocity.

The Dynagage Flow10 Sap Flow system and Dynagage sensors have been servicing research plant scientists throughout the world for over 30 years. The Flow10 software makes working with Flow10 sap flow system easier than ever before with built-in algorithms for efficient and faster data analysis. Powerful functions include auto-zero and sensor status built into the data logger program. Sap flow data recalculation and automatic charting with an Excel™ Macro link makes the system a superior water relations measurement system. Sap Flow has never been this easy and powerful.

The FLGS-TDP XM1000 system is a complete CR1000x based logger system for 32 TDP probes. The CR1000x is housed in a weather-resistant enclosure while collecting data under extremely harsh conditions. The AM16/32 Relay Multiplexer increases the number of sensors that may be scanned by the CR1000x data logger. The PC400 data logger support software for windows facilitates programming, communication, and reliable exchange of data between a PC and a CR1000x data logger. The interactive toolbar launches and controls independent windows used to communicate with the data logger, edit programs, view and graph real-time data, retrieve stored data, and process data files. The minimum requirements include: Windows, 15MB disk space, VGA monitor, RS-232 port(s) for modem or serial communication interfaces.
