The NIR 6100 Series of On-Line IR Moisture Analyzers are designed for food grade applications. The nickel plated surface provides additional protection from corrosion and largely eliminates the risk of abrasion and issues related to the porous nature of standard metallic enclosures. Its NEMA 4X rating allows light wash-downs, and promotes a high level of protection from contamination, bacteria, and other hazards typically associated with food processing.

Non-Contact Sensor

It is ideally suited for food processors concerned about regulatory compliance or simply wanting a higher standard for their food application. The non-contact characteristic of Sensortech’s IR Series reinforces your processes standard of cleanliness and hygiene while maximizing productivity by reducing downtime with its maintenance-free operation. The NIR 6100 bridges the gap between productivity and health code compliance.

The NIR-6300 Harsh Environment Analyzer is an ideal solution for food processors operating in high temperature environments. The stainless steel enclosure provides the highest level of protection essential to food grade applications. The IP67 rating permits the analyzer to operate in environments having excessive debris where the feasibility of performance for the 6100 Series is limited.

NIR-6100 and NIR-6300 Performance

  • Innovative Optical Design
    The IR Series optical design provides a foundation of measurement stability and reliability. High precision tolerances of machined parts and alignment of optical components enusure optimal performance.
  • Single-Point, Dual-Purpose Detector
    The long established Quadrabeam Principle combines the measurement light path and the direct (prime) light path onto a single detector eliminating variations due to aging and operating temperature more effectively than expansive matched dual detector products. The large surface area detector (10mm sq.) minimizes error due to product height variation.
  • Collimated Energy Source
    Effective use of power dramatically increases optical efficiency enabling the instrument to run significantly cooler. The reduced operating temparature inherently reduces stress on electronics and power supplies, increases the life of the instrument and further reduces costs associated with added temperature conditioning.
  • Optimized Electronic Signal Conditioning
    Oversampling, 16-bit resolution and multiple-level digital filtering minimize signal noise. Proprietary design and state of the art electronic technology further enhances instrument performance.

Process Integration

Integrating moisture measurement and control into your process is a simple task with the IR Series moisture analyzers. A wide range of communication protocols are available for a networked multi-sensor configuration or as a stand-alone instrument.

Communication Protocols

The NIR-6000 includes standard features such as Ethernet TCP/IP, RS-232, RS-422/485 and three self-powered isolated 4-20mA analog outputs designed to integrate into your distrubuted system. Implementing continuous moisture measurement into your process is a simple task with Sensortech.

Local Moisture Display

HMI interfaces or Remote Digital Displays are mounted at the point of measurement and provides a stand-alone intelligent interactive interface to the IR Series analyzer or a visual indication of your processes moisture control status.

Network Communication Ethernet 4-20mA and RS-232

Management Software

The NIR-6000 Series analyzers include a proprietary PC based software package that offers a detailed view of your production process from a desktop or laptop computer.

Measurement display, data-logging, calibration utilities and network configurations are among the many features included with your NIR-6000 Series Management Software.
