MicroNIR PAT-Lx – Viavi (NIR) ATEX Certified

MicroNIR PAT-Lx is a robust near infrared (NIR) process spectrometer for analysing liquids in hazardous locations. Safe in the presence of flammable gases, vapors, or dust, the PAT-Lx enables rapid and repeatable analysis of a wide variety of liquids, aqueous or hydrocarbon-based. 

The MicroNIR PAT-Lx consists of two main parts: The instrument head with probe and the barrier box, connected by a hardwired USB cable. The instrument head is identical to the MicroNIR PAT-L and consists of a spectrometer section and a probe section with integrated light pipe. The barrier box houses the interface electronics in a heavy, ruggedised cast aluminum enclosure. The barrier box has user-available ports for connections to Ethernet, 24 V DC power, and optional external trigger, using customer-supplied connections rated for hazardous locations.  

Viavi MicroNIR Pat-Lx

Immersion Spectrometer: A robust near infrared (NIR) process spectrometer for analysing liquids in hazardous locations.

Rugged and safe in hazardous locations, the MicroNIRTM PAT-Lx process spectrometer is designed for real-time process monitoring of liquids in vessels and pipelines.

The PAT-Lx is the hazardous location version of the VIAVI PAT-L immersion process spectrometer. Safe in the presence of flammable gases, vapors, or dust, the PAT-Lx enables rapid and repeatable analysis of a wide variety of liquids, aqueous or hydrocarbon-based. The PAT-Lx integrates readily with processing equipment of all types and sizes, and delivers the performance, stability, and total cost of ownership to meet the stringent requirements of scalable manufacturing.

Key Features

  • Non-destructive, real-time NIR liquid analysis for hazardous locations
  • Safe in the presence of flammable gases, vapours, fibres, or dust.
  • ATEX, NEC, IECEx certified
  • Maintenance-free with no moving parts for total cost of ownership
  • Rapid data acquisition up to 3 spectra per second for fast moving processes
  • Robust, reliable, and repeatable
  • Washable, IP65 and IP67 rate

Applications

  • Chemical Manufacturing
  • Polyols and hydroxyls
  • Water content
  • Density, viscosity
  • Blend homogeneity
  • Solvent recovery
  • Food Production
  • Frying oil degradation
  • Sugar concentration
  • Pharmaceutical Manufacturing
  • API crystallization
  • Solvent recovery

Software

Like all MicroNIR instruments, the PAT-Lx includes the VIAVI MicroNIR Pro software suite with features for data acquisition, calibration and method development, user management, and real-time prediction. MicroNIR Pro software supports instrument qualification (IQ/OQ) per EP 2.2.40 and USP 1119/1856 test criteria and software tools to meet rigorous Title 21 CFR Part 11 compliance. An enhanced OPC interface is optionally available for integration with process control systems.

Process Integration

The MicroNIR PAT-Lx can be mounted to standard sanitary flanges using a collet assembly and tri clover clamp, or via flange if so equipped. Installation in hazardous locations requires trained and/or certified personnel and must conform to local regulations

Product Description

The MicroNIR PAT-Lx for hazardous locations consists of two main parts: The instrument head with probe and the barrier box, connected by a hardwired USB cable (see Fig. 1). The instrument head is identical to the MicroNIR PAT-L and consists of a spectrometer section and a probe section with integrated light pipe. The probe operates in transmission mode with an optical path length (gap) specified when purchased. The barrier box (see Fig. 2) houses the interface electronics in a heavy, ruggedized cast aluminium enclosure. The barrier box has user-available ports for connections to Ethernet, 24 V DC power, and optional external trigger, using customer-supplied connections rated for hazardous locations. The barrier box comes with mounting brackets for attachment to process equipment.
