AMETEK PI - Model IPS-4 -Integrated Photometric Spectrometer

The IPS-4 is engineered for outdoor installation, so it can be sited close to the process being monitored, minimizing sample transport delays and the need for expensive instrument shelters.

Providing an economic, user-friendly solution for online process analysis of gases and liquids, the IPS-4 is ideal for use in the hydrocarbon processing and natural gas industries.

MULTIPLE GAS CAPABILITY
Three different platforms offer the analysis of multiple gas components suited to specific applications. UV analysis is free of cross-interferences from lighter hydrocarbons, carbon dioxide and water, while IR provides powerful component concentration measurements.

VERSATILE INSTALLATION OPTIONS
With no exposed parts, the IPS-4 can be mounted in demanding environments, including outdoor, wash-down and hazardous locations. It still provides the user interfaces expected in production environments. A fiber-optic version is available, which keeps the electronics away from highly corrosive conditions.

EASY TO MAINTAIN
The optical bench of the IPS-4 contains no moving parts, and uses a xenon lamp with an expected lifespan exceeding two years. The integrated sampling system reduces both maintenance and installation requirements.

The IPS-4 is the cost-effective, reliable solution for on-line process gas and liquid analysis – Find out more.

• Multiple gas capability
• Integrated, customizable sampling system
• Designed to analyze hot and wet samples, reducing the need for coolers or chillers
• Low cost of ownership
• Analog and digital connectivity options

AMETEK’s IPS-4 UV analyzer is a huge step forward in capability and reliability for process spectrophotometers. Using the most modern electronics and diode array technology, the IPS-4 is engineered to perform a wide variety of liquid and gas analyses using UV-VIS spectroscopy.

Analytical Performance

The IPS-4 is capable of detecting, quantifying, and compensating for multiple chemicals of interest and interfering species. Up to eight analytes of interest can be measured simultaneously through the combination of a modern, diode array-based optical system with our proprietary process-ready electronics.

This combination offers many advantages such as no moving parts, a high signal-to-noise ratio, minimized stray light effects, fast and full spectral acquisition, and wide dynamic range. These traits help to make the IPS-4 a highly capable process analyzer.

Optical System

The IPS-4 UV’s optical system is designed to increase reliability and dramatically reduce the need for routine maintenance, thereby drastically cutting its cost of ownership. The lamp used in the optical system is a xenon flash lamp which has a greater than two year expected life. Use of the diode array and fixed optical bench means that there is no filter wheel or motor to maintain, no optical filters to replace, and no optical couplings to align. The resulting optical system is small, insensitive to mechanical tolerances, insensitive to movement, and free of moving parts.

The AMETEK-designed electronics are engineered to withstand harsh outdoor, industrial environments. They possess excellent temperature stability, reliability, and a host of self-diagnostic and predictive maintenance capabilities. The combined result of the IPS-4’s design is a spectrophotometer with high reliability and a minimal need for routine maintenance.

Interface Options

Manufacturing facilities have a wide variety of communication needs from their process analyzers. To meet the varied needs of our customers, we have equipped the IPS-4 with numerous analog and digital communications capabilities. A detailed, multi-line display along with a 22-key keypad provides the primary local indications. The keypad is a stainless steel, piezo-electric device which is the ultimate in durability and reliability. The pixel-based display is detailed enough to allow for a selection of display language. The analyzer also communicates through a variety of analog signals, alarm contacts, and three types of digital communication.

Digital communication options include a RS-232, RS-485 with MODBUS RTU protocol, and a built-in Fast Ethernet port.

Wide Environmental Tolerance

Process analyzers must often be installed in harsh environments. Unlike other process analyzers, the IPS-4 is designed to handle most environmental challenges without the need for additional protection or prohibitively expensive shelters.

The IPS-4 is supplied in an IP65 NEMA 4X optional enclosure. This enclosure is more than capable of handling even wash-down environments without allowing water or dust to ingress. The standard enclosure is made from 304 stainless steel, with 316 stainless steel as an option.

When installed outdoors, the IPS-4 will tolerate ambient temperatures from -20° to 50°C (-4° to 122°F) without external heating/cooling. When installed indoors, the analyzer takes up minimal space as it is designed with a very narrow profile. The width of the IPS-4 has been kept to only 78 cm (
Custom Sampling Systems

The IPS-4 is engineered to be a fully integrated, turn-key solution to your specific process analysis need. AMETEK will engineer a sample handling and conditioning system to meet the requirements of your sample fluid and application. Automatic zero and span fluid injection, corrosion-resistant materials, filtration, pumps or eductors, and heated sample lines are a few of the customizations AMETEK can engineer into the IPS-4 to meet your application requirements.

The IPS-4 may be the solution you need to improve the quality and efficiency of your process. Contact your AMETEK Process Instruments salesperson to discuss your specific application today.
