The Next Generation solution for industrial on-line moisture sensing

Wavetester is a innovative system for the non-invasive (contactless), non-destructive and real-time moisture analysis of materials.

The Problem:
Many industries need an accurate and continuous monitoring of the water content of materials being processed. The sensor should measure the entire volume of the material, provide fast results, require no maintenance and have a long lifetime...

The Solution:
Wavetester™. Its innovative operating principle does not require any contact with the material to be analyzed, yet it allows scanning through its entire cross section. The results are that no moisture "hot spots" go undetected and that the sensor is not subject to any abrasion or wear, therefore lasting almost forever.

How it works:
A low power microwave signal is sent through the sample. The system compares the transmitted and the received signals by means of sophisticated signal processing hardware and software algorithms and extracts 3 or more moisture readings per second.
Wavetester has been developed in cooperation with the researchers at the TTHFLab of SUPSI (University of Applied Sciences of Southern Switzerland) and is the result of many years of research.

Application areas:

product quality control closed loop moisture control cost optimization and output control in drying processes organic products' storage monitoring etc.

A few application examples: (click on the images to enlarge)

water addition dosage (concrete production)
tobacco quality control
drying control in leather industry

USBKey

USBKey is a programmable USB HID (Human Interface) device with 10 configurable inputs as well as an integrated RS-232 serial port. When plugged into a USB port of any personal computer (PC, Mac), it is immediately recognized as a HID peripheral (keyboard, mouse), without requiring any additional software driver installation.

USBKey was originally developed as an assistive device for our partner, FIPPD.

Using our USBKey Configurator Software (for PC/Mac), each of the 10 inputs can be freely and independently configured as:

• a mouse button (left, middle, right)
• any key of an extended 101 keys keyboard (including the function keys and the numeric keypad)

When one of these inputs is activated, the computer will behave as if a standard mouse or keyboard generated the command. Being supported by the operating system, this functionality will work with any application software.

USBKey also has the following additional features:

• hidden (phantom) inputs: an input configured as "hidden" will only be recognized by applications designed to make use of this function. This can be easily implemented by using our API software functions and code examples.
• a RS-232 serial port is available and can be useful when the personal computer to which the USBKey is connected lacks of such an interface

Applications:

keyboards and keypads on PC based machine tools and instruments
assistive technology Read more here....

 

USBKey is also available in an OEM version, without enclosure:
