CM710e The Measure of Quality™
On-line Measurement NDC & Industrial Processing NDC Infrared Engineering has over 40 years of experience in the design and manufacture of on-line instruments developed specifically to meet process industry’s exacting requirements for moisture measurement. Our development team has in-depth knowledge of the physical and chemical attributes of the many products that we can measure, the measurement and control requirements in the process, and the laboratory and analytical methods used in quality assurance systems. Furthermore, we understand the ambient conditions in the process, and engineer our gauges to be insensitive to changes in relative humidity, factory lighting, process temperature and product presentation. The objective is to develop accurate, stable, robust moisture measurements that are trusted for process control. Each CM710e Gauge is supplied with NDC’s unique SpeedCal pre-calibration, leaving our facility ready to be installed in the process and quickly set up to give high performance measurements from day one. Direct operations in Europe, Asia & the Americas and fully trained distributors world-wide, ensure that you can rely on NDC for first class local support.
Using Accurate Moisture Control to improve quality & efficiency whilst reducing energy consumption...
Industry drivers
Process Efficiency Improvements Product Quality Reducing fossil fuel consumption Introduction of GMP
The Challenge, however, is to introduce into the process a measurement which will be robust and stable enough to meet the environmental demands and accurate and reliable enough to be trusted for process control. The nature of the process also demands specifically engineered solutions to gain access to the product to make an effective measurement.
Implementation of automated closed-loop control systems
Automated Process Control based on real-time on-line moisture measurement delivers some of the most significant savings in industrial processing through the improved efficiency of drying processes. Controlling and increasing product moisture content by just one percent or even less can achieve substantial improvements to process profitability while reducing energy consumption and factory emissions.
Moisture Content also plays a major role in product quality; whether optimizing spray drying of ceramic powders, controlling moisture in copper concentrates, achieving target moisture values in sinter mix, or monitoring moisture in powdered detergents – these and many other processes can benefit from tighter control of moisture levels.
Many products are transported on conveyors providing convenient measurement access, but pneumatic transport systems will require automatic samplers and discontinuous product flows require product presence/ absence detection, and for really aggressive locations, ruggedized housings and mechanical protection will be required. In hazardous areas, there may be a need for ATEX certification.
On-Line Instrument Design must fundamentally ensure that changes in the measurement output are due solely to the varying levels of product moisture and not because of product or process variables.
The CM710e Industrial Moisture Gauge Designed specifically for use in an Industrial Process the CM710e’s robustness and stability deliver performance which is universally trusted for process control... The CM710e uses precision NIR (near infrared) measurement technology to make a continuous non-contacting measurement of moisture. With a measurement speed of 7.5 milliseconds, the patented “light engine” uses optical components manufactured by NDC’s Optics division, to deliver the highest resolution on-line measurements available today. The CM710e is designed for incorporation into closed-loop control systems. Connectivity options include:
■ ■ ■ ■
Digital Analogue Industrial Ethernet Fieldbus
Using industry-standard Ethernet communication hardware such as hubs, cables, repeaters and routers, installation and integration of the modular CM710e gauging system is straightforward. For network integration, the Gauge can be configured for the following industrial Ethernet protocols:

are available to connect to the gauges via standard Cat5E cable, including:
Operator Workstation (OWS) Human Machine Interface (HMI) User Port Switched Network Hub
The OWS provides operator-level interaction with an individual gauge; the HMI provides supervisory access to up to 16 networked CM710e gauges. Both units feature high definition multi-lingual colour touch screen displays. The User Port provides additional analogue outputs and digital I/O for any connected gauge. For simplicity and convenience, all CM710e system components run on 24V DC, either from an on-site supply or from an NDC in-line 24V universal power supply. Long term stability, industry-best performance, low installation costs and no routine maintenance requirements guarantee the lowest cost of ownership over the CM710e’s many years of service.

The NDC CM710e Recommended Gauge Configuration with Stainless Steel Sensor Housing, Air Purge Window Shield & Operator Workstation
How the CM710e works Light from a QH lamp is split into sequential pulses of NIR energy at wavelengths which are absorbed by the parameter being measured. Before emitting the light onto the product, the CM710e diverts a portion of the beam onto the secondary detector, to form the reference signal against which the returning diffusely reflected light will be compared. The light leaving the CM710e interacts with the product and any unabsorbed energy is reflected back into the instrument, captured on a special 24 segment mirror and focused onto the primary detector. The signals on the primary and secondary detectors are then processed via the appropriate measurement algorithm to generate a linear output which responds proportionally to changes in the product moisture. The patented optics reject influences due to changes in ambient lighting, RH and temperature to provide a highly stable measurement, irrespective of product height fluctuation.

The Measure of Quality™
CM710e Installation Guidelines Installation The CM710e measures over a 60mm diameter area (optionally 25mm) and should be attached to a sturdy support and suspended over the conveyor or process line at a distance from the mean product height to the CM710e measurement window of 250mm. The gauge tolerates product height fluctuations of ±100mm, without affecting the measurement. The Operator Workstation should be installed near the gauge in a position where the display is clearly visible.
Discontinuous Product Flows Optional “gating” systems are available, with automatic product presence/ absence recognition (using optical or ultrasonic sensors) for discontinuous product flows.

Ambient Conditions The CM710e’s alloy or stainless steel housings are sealed to IP65 standard and can operate in ambient temperatures between 0 and 50OC without cooling. The stainless steel housing is also available in IP67 and ATEXcertified versions. A vortex cooler attachment or insulated air-cooled housing are available for ambient temperatures exceeding 50OC. An optional Air Purge Window Shield connects to a clean air supply to create a positive air pressure in front of the measurement window to prevent contamination. Ambient lighting or relative humidity changes do not affect the MM710e measurement.
