  1. EXO-Skin Sap Flow Sensor • New Design Stem Heat Balance (SHB) • Same Accuracy, More Flexible • Less Maintenance • Lower cost • EXO (= outer, Greek) SKIN

  2. Mechanical Specifications

  3. Heater / Signal Integration • New Heater layers add durability • Thermocouple wiring similar to Dynagage sap flow sensors • No change to accuracy • Thermo sensors adapt to irregular stems (Grape Vine example) • All EXO-skin come with sealed water tight locking connectors • Advanced Seal Liquid tape. • Add lifetime to 3-5 years • ( with annual maintenance avail at distributor)

  4. Electrical Specifications

  5. System Connections • Signal Names • Same as Dynagage • Attach to CPC circular plastic connector (9pin) • To SapIP – dual sensor cables • SPIP-CS1, SPIP-CS2 • SPIP-CS4 and extensions. • To Flow 32 Extensions • Cable EXQC –25, -50, -75 • FLDL - EXQC

  6. Velstretch Wrapping • Stretch Velcro • wrap around the sensor to plant • Reduce maintenance • Better installation • Accommodate growth • Velstretch made of breathable Material, • Porous nylon • Lycra spandex • Collects moisture and conducts water from the stem and sensor • Reduce Mildew and less stem damage.

  7. Environmental Specification

  8. Insulation Provided • Three Pieces • With every sensor • Attachment is double sided Velcro Wrap • Need to protect from rapid ambient Temp swing • Reduce NTG

  9. Waterproof Membrane Cloth • Rain Coat • Membrane cloth wrapped over insulation • Teflon fabric (Gore Tex) • Extracts water vapor • Reduce condensation build-up inside • Reduce corrosion or stem damage

  10. Wrap & Protection Specifications

  11. Reflective Shield • Material consists in 2 reflective layers on layer of plastic bubbles • Required to block radiant heat • Reduce Natural Thermal Gradient (NTG) by insulation on trunk below sensor. • Provides a conductive barrier

  12. Complete Installation • All parts should install in 10 to 20 min • Depends on bark or cleaning preparation • If required. • Assistant holds parts • Helps manipulate attachments • Cut Velcro into smaller lengths

  13. Applications • Odd plant stems and shapes • Stem fast growth • Crops • Understory • Vines • Trees • Vegetables • Research and Commercial Monitoring

  14. Summary • Low Cost (-25%) • Same Accuracy • Less Maintenance • Easy Installation • Compatible with all Dynamax sap flow loggers • Thank You!
