The HumiCore in-line moisture measurement sensor ensures product quality by measuring the moisture inside the material core…not just the surface. It is a reliable, continuous on-line system that provides real-time data. Allows for automation of drying or moisturizing at different points in processes to minimize energy costs and maximize profits. The well-designed compact sensor, which is easy to install and calibrate, works with a large variety of powders and bulk solid materials. The HumiCore is available in an Ultra version with a controller for local interface and data logging or a Pro version with a DIN-Rail transmitter for easy integration into an existing control system.

Industry Applications


Many plastic processors with multiple manufacturing locations have this problem. The solution for Nursery Supplies was the implementation of a RMI (Remote Managed Inventory) system. Monitor Technologies specializes in RMI and VMI (Vendor Managed Inventory) systems using the SiloPatrol® inventory monitoring system with SiloTrack™ inventory management software. SiloTrack software enables local control and interface of the sensors and provides for communication to remote locations with its Client software. Nursery Supplies has a total of over thirty (30) SiloPatrol® sensors in use at four (4) facilities. Each facility uses the SiloTrack™ Server software and the Client software is also installed at the corporate location for central purchasing use. The Client software interfaces with the Server software at each facility via dial-up, LAN or WAN connections. Nursery Supplies has been able to reap the benefits by being able to automatically view inventory levels at all facilities and place orders accordingly. Nursery Supplies indicates that "Monitor's SiloPatrol/SiloTrack RMI solution is an economical, accurate and trouble-free measuring system”.


Many Food industry manufacturers, including snack food manufacturers, have found a solution with the TrueCap® Model MK-2 RF capacitance point level sensor.

The MK-2 sensor combines a unique automatic temperature compensation function, a state-of-the-art microcontroller and the use of high quality industrial and mil-spec electronic components to ensure stable calibration to within its specification of +/- 0.01pf per degree F (0.018pf per degree C).

The TrueCap MK-2 also uses surface-mount components and provides a universal power supply and high-intensity LED’s for local indication of material presence/absence (ordinary location units only).

The MK-2 is available in a wide variety of probe configurations including food-grade acceptable materials of construction. The MK-2 has been providing stable installations free of re-calibration for several years.


Bins in a seed treatment system may not be very large.  In this specific application the largest measuring range needed was 15.75’ (4.8m) and the shortest measuring range was 5.25’ (1.6m).  With measurement accuracy to 0.8” (20mm) and measurement technology that works at the speed of light, guided wave radar proved to be the best solution.  This seed treatment operation utilizes a total of fifteen (15) Flexar® guided wave radar continuous level sensors.  These instruments use TDR (time domain reflectometry) technology.  The distance/level of the seed is measured by the time-of-flight of the reflection of a microwave signal (1Ghz), transmitted down the wave-guide at the speed of light, off the material surface.  The sensor cable probe is a heavy-duty 0.3” (8mm) diameter stainless steel cable.  The seed in this application is corn and has a bulk density of about 45 lbs/ft3 and a dielectric constant of about 5.0.

The signal from the Flexar level sensors indicates the seed dielectric was actually about 3.5.  The signal diagram indicates the measurement reflection as well as the reflection from the top and bottom of the counterweight.  The time lag from the material level to the counterweight was due to the material presence.

This was an excellent application for guided wave radar technology and the units are functioning to specification.
