AquaSense is a moisture probe or sensor, for use in sand, powders and granulated materials.  Its hard ceramic faceplate is rugged and hard wearing, giving 10 to 20 years service in concrete applications.
Measuring range: 0 – 20% moisture, calibrated for sand. Other ranges and materials on request.Can be calibrated for surface or total moisture, “wet” or “dry” calculation basis.
Material limits: From powder to ¼” granule size. Readings become more erratic as size increases.
Sensing volume: W=2″ X H=2″ X D=10″ at 2% moisture, to  D = 2″ at 10% moisture (in sand).
Analog output: 0-20mA, 4-20mA. 0-5V, 0-10V etc. by use of external resistor.
Digital RS232 & RS485 connection: Bidirectional, industry standard protocol and command structure supports up to 16 moisture probe on the same RS485 line.
RS232/RS485 Display & setup: Windows software displays readings, and allows access to setup and calibration menus.
Material calibration storage: Up to 10 separate sets of material calibration parameters per moisture probe.
Power: 11 – 30VDC, 100mA
Sampling input: Dry contact or relay from feed gate signal to moisture probe. Optional replaceable relay in junction box.
Bin low and alarm outputs: Three open collector transistors to drive relay or PLC input. Optional 140VAC 6A solid-state relay for Bn Low in junction box; other outputs require separate relays.
Temperature range: Full accuracy: 0-50°C (32-120°F).  Reduced Accuracy: 0-80°C (32-175°F)
Construction: 304 stainless steel body and flange with shatterproof extra hard alumina ceramic faceplate.
Size: 3-1/2″ (89mm) diameter, 20″ (508mm) long with 6″ (152mm) adjustable flange for correct positioning.
Guarantee: 10 year guarantee on material and workmanship; return for replacement.
