Introducing our SONO® Standard Conveyor Moisture Meter for sand and aggregates, providing reliable on-line moisture measurements for seamless process control.
Introducing our SONO-VARIO® Conveyor Moisture Meter for sand and aggregate applications, a pivotal member of our SONO® sensor range, delivering real-time moisture measurements on conveyor belts and beneath silos.
Accurate real-time monitoring of moisture levels in sand and aggregates is essential for optimizing operations in the construction in concrete production. Our specialized SONO-VARIO® Conveyor Moisture Meter is designed to precisely measure moisture content in various types of sand and construction aggregates used in concrete production, empowering users with complete control over product quality.
At the core of our sensor technology lies the revolutionary TRIME® TDR Technology. This patented innovation enables direct mounting onto conveyor lines, ensuring continuous penetration into the material for highly accurate and consistent moisture readings of 0.1% or better.
With over two decades of expertise, Seztec’s moisture probes are the trusted choice for sand and aggregate moisture measurement needs, providing efficiency gains and cost savings in your operations.
The innovative feature of SONO-VARIO’s sensor head replacement offers significant cost savings and reduces downtime. Instead of replacing the entire unit, users can simply replace the sensor head when necessary, minimizing maintenance costs and ensuring continuous operation without prolonged downtime.
The supplied mounting plate assembly facilitates quick and straightforward installation of SONO-VARIO® Conveyor Moisture Meter directly onto conveyor belts, eliminating the need for complex setup procedures. This plug-and-play design minimizes installation time and ensures hassle-free integration into existing conveyor systems.
Choose from 15 pre-programmed standard linear calibrations, allowing you to select the ideal setting for various sand and aggregate types, perfectly aligning with your sand moisture measurement requirements.
For highly abrasive aggregates such as gravel, rock, crushed stone and RAP (Reclaimed Asphalt Pavement), up to 1-1/4 inch, our SONO VARIO – Xtrem Aggregate Moisture Sensor will be suitable. Contact us to find the right sensor for your application.
