Series 9 Converting Moisture Gauge

On-line Near Infrared (NIR) Moisture and Coat-Weight Measurement Sensor for Converting Industry

On-line Moisture Gauge

The Series 9 NIR Converting Moisture Gauge is the latest generation sensor for precise on-line measurement of moisture and coat-weight thickness in the coating and converting industry. Mounted above the web, the Series 9 Converting Moisture Gauge offers dependable, stable and accurate real-time, on-line simultaneous measurement of both moisture and coat-weight. Delivered pre-calibrated, the gauge offers unparalleled performance and is highly tolerant to the changing conditions specific to the coating and converting industries. Constructed from 316L stainless steel protected to IP67 and fitted with a tough sapphire window with built-in air purge protection, the gauge is ‘fit for purpose’ for use even in the harshest applications.

Multiple User Interfaces to Suit Every Situation

Several types of gauge displays are available to meet the needs of different customer requirements, all are equipped with a modern high resolution 10” colour, touch screen interface with intuitive, easy-to-use software. The simple, lower-cost Operator Terminal (OT) provides a large, easy to read display of measurements and basic gauge functions. The sophisticated Gauge Control Interface (GCI) can manage networks of multiple gauges, providing advanced configuration, data storage/trending and diagnostic functionality. A ruggedized, portable tablet with embedded software for managing multiple gauges, with a convenient wireless connection to the gauges is also available.

Connectivity and Industrial Interfaces

The Series 9 NIR Converting Moisture/Coat-Weight Thickness Gauge can be easily incorporated into any new or existing process using its digital I/O and networking options. Up to 16 gauges can easily be networked (daisy-chained) and connected to an existing PLC or SCADA systems using a number of industry-standard protocols including EthernetIP, ProfinetIO, ModbusTCP, DeviceNet and ProfibusDP. In addition, eight digital I/O and analogue outputs are also available.

Accessories and Options

A full range of accessories and options are available to simplify installation and to ensure that the system is correctly specified for dependable and reliable operation for specific applications. Options include air or water cooling/heating, adjustable mounting brackets, cabling options, gating for measurement of discontinuous products, powder vision for measuring powders in ducts, measurement beam size, product temperature sensing and special product viewing ports

Lowest Cost of Ownership

Long-term stability combined with industry best performance, low installation costs and no routine maintenance requirements guarantee the lowest cost of ownership over many years of service.

Operating Principle

The Series 9 Converting Moisture/Coat-Weight Thickness Gauge measurement sensor works on the principle that moisture molecules (or coating) within the product being measured discretely absorb a certain wavelength of infrared (IR) light. By pulsing light at these wavelengths onto the product and then capturing and measuring the reflected unabsorbed light on a light-sensitive detector, it possible to determine exactly by how much each wavelength is being absorbed.  Using advanced process algorithms and high-speed signal processing, it is possible to provide a direct moisture measurement for any given material that is presented. The measurement is unaffected by changes in process conditions such as particle size, product height temperature, ambient lighting and relative humidity changes.
