AquaControl  controls the water dosing in the mixer to give consistent moisture or slump in the final product.
AquaMix 2270D is a moisture sensor for use in mixers used in concrete production and other applications where there is severe abrasion.

AquaMix 2270D measures moisture in concrete mixers.  It communicates with a control system which corrects the water in the mixer to give constant yield, colour/texture and workability, as well as strength and durability.  For more general information on moisture measurement, see our range of Moisture Sensors.

Measuring range: 0 – 20% moisture, calibrated for ‘average concrete’. Other ranges and materials on request.
Material limits: From powder to mix of granule sizes up to 1/2″. Longer average required for larger sizes.
Sensing volume: W=2″ X H=2″ X D=4″ at 5% moisture.  D ∝ 1/(moisture)
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 sensors 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 mix design calibration parameters.
Power: 11 – 30VDC, 100mA
Alarm outputs: Open collector transistors to drive relay or PLC input. Optional 110-140VAC 6A solid-state relays in junction box.
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 silicon nitride ceramic faceplate giving over 10 years life with hard usage.
Size: 3-1/2″ (89mm) diameter, 10″ (254mm) long with 6″ (152mm) adjustable flange for correct positioning.
