NDC gauges are used in production processes to improve quality and reduce costs. At Powtech, NDC presents its solutions for continuous measurement of moisture content for the bulk, chemicals and minerals industries.
More energy is expended during drying than at almost any other stage in industrial processing. Poor control of the drying process results in wasted energy, higher production costs and out-of-spec products.
The CM710e industrial moisture gauge is designed to help manufacturers of powders, coarse or fine particles, concentrates, slurries, pastes, flakes, granules and similar product formats to optimize their process by providing real-time moisture measurements that can be used to control the process, monitor product quality and warn operators if the process is moving out of specification, thereby increasing yield and improving and maintaining quality. The efficiency improvements can result in substantial cost reductions, with return on investment achieved in months.
The CM710e uses precision NIR (near infrared) technology to make a continuous non-contacting measurement of the moisture content. While accurate to laboratory standards, the CM710e is nevertheless robust enough to survive in an industrial processing environment, and there are a number of options and accessories available to give added protection in the process environment.
The CM710e works on the principle that moisture (water) discretely absorbs certain wavelengths of infrared light. By emitting light at these wavelengths onto the product and then capturing and measuring the reflected unabsorbed light on a light-sensitive detector, the CM710e computes the level of the moisture within the product.
Using highspeed signal processing, the patented 710e “light engine” delivers the highest resolution on-line NIR measurements available today and is unaffected by changes in process conditions such as particle size variation, product height variation, product temperature variation, ambient lighting and relative humidity changes.
The CM710e is typically located over a conveyor belt at a key point in the process: just after a drying process for example, where the product can be measured to give meaningful feedback for process and quality control. It can also be used with an NDC Powdervision in-process powder sampling system.
The CM710e can be incorporated conveniently into closed-loop control systems, using its digital or analog connectivity options, while data can be displayed locally for operators using the 710e Operator Workstation or HMI.
The CM710e is used in conjunction with one or more 710e Peripheral Devices to facilitate data display, networking and process connectivity. Gauges and devices are Ethernet enabled and connect to each other via standard Cat5E cable and all run on 24V DC power. Available devices include:
• OWS – Operator Workstation - for local display of a single gauge and industrial Ethernet or Fieldbus connectivity
• HMI – Human Machine Interface - for remote display and supervisory control of up to 16 gauges as well as Industrial Ethernet or Fieldbus and analog connectivity
• User Port – for additional digital and analog connectivity
• Switched 7 - Way Networking Hub - for convenient network structures
