Moisture Sensors for Fresh Concrete

MESA Systems Co. offers three moisture measurement sensors versions for your on-line fresh concrete measurement needs. Designed for installation directly in the mixer, these probes and sensors are both user-friendly and intelligent.

How moisture sensors work:

The SONO-MIX sensor for mixers offers precise moisture and conductance measurements. These measurements enables the correlation of additional recipe parameters such as the cement content and slump of fresh concrete. The SONO-MIX is capable of measuring fresh concrete, including carbon fiber concrete. Measurement values, taken at intervals of 4 per second, are transmitted to your desired batching system or local notebook computer. Interfacing to common batching control system is simple using the available analog output.

Why SONO-VARIO:

Unlike other moisture measurement probes, the SONO-MIX sensors’ measurement field adapts to the material being measured. SONO-MIX probes provide accurate measurement values even when conditions present difficult conditions such as, exposure to steam in winter, and varying size of aggregates. In addition, the SONO-MIX sensor is highly accurate even in wet mixtures. SONO-MIX’s accuracy in wet mixtures allows the possibility to dose the water addition, very precise, by using recycled water. Furthermore, even in the event of abrasion at the probe head, the automatic measurement compensation feature enables significantly longer operating periods without the necessity of re-calibration. Achieve reliable quality control and higher cost-effectiveness by preventing recipe errors with precise measurements.

SONO-MIX Technology:

All SONO-MIX sensors use TRIME® TDR-method for moisture measurement, more commonly known as Guided Wave Radar or Cable Radar. Cable Radar uses a high frequency low voltage pulse that travels along a radar track, embedded in the surface of a SONO-MIX sensor. The pulses travel close to the speed of light generating a measurement field that propagates in slices out from the sensor’s surface, similar to computer tomographic (CT-scan) but for moisture measurement.
