Product catalog summary

Overview: The document introduces the PUV3402 and PIR3502 Multiwave™ Process Photometers, designed for on-line measurement of gas or liquid components in various process streams. These photometers are used for process control, product quality assurance, safety, catalyst protection, and area monitoring.

Specifications: The photometers operate in the IR, NIR, UV, and VIS spectral regions, with a fiber optic option for NIR applications. They feature multiple interference compensation capabilities and can measure vapor or liquid samples. The PIR3502 is suitable for Infrared and Near Infrared measurements, while the PUV3402 is designed for Ultraviolet and Visible spectral regions.

Connectivity: The devices can be connected to ABB Analytical’s VistaNET™ Process Analyzer Network, allowing data interchange with the Distributed Control System (DCS) and remote user access. This network supports seamless connectivity to the plant operating system and enables remote configuration, operation, and troubleshooting.

Design and Reliability: The photometers are built to withstand challenging process environments, including temperature variations, moisture, corrosive and explosive compositions, and electrical hazards. Key features include solid-state detectors, a brushless chopper motor, a linearizer circuit, an isolated sample cell, self-aligning optics, and a temperature-controlled filter assembly.

Performance Specifications: The photometers offer precision of ±1% of full scale, noise levels of ±1% at 0.02 absorption units, and standard linearity of ±2% of full scale. They have programmable response times and maintain ambient electronic stability within ±1% of full scale for temperature changes.

Operating Specifications: The devices operate within a wavelength range of 200–14,500 nm and an ambient temperature range of 32° to 113°F. They support sample flow rates of 20–500 cc/min for vapors and 5–120 cc/min for liquids, with a sample pressure range of 0–500 PSIG.

Installation and Maintenance: The photometers should be protected from direct sunlight and rain, with dimensions and weight specified for installation. They feature easy component removal and replacement, reducing maintenance time.

Output and Classification: The devices provide analog outputs, contact closures, digital inputs, and outputs. They are classified under various safety standards, including NEC and CSA, for different hazardous area classifications.
