searchpoint Optima Plus including HART Point infrared Gas Detector

Searchpoint Optima Plus is a market-leading Point IR (Infrared) gas detector offering high performance detection of a wide range of Hydrocarbon gases. With immunity to adverse weather affects such as snow, fog, rain and sunlight, and fail-to-safety operation, Searchpoint Optima Plus provides a flexible monitoring solution that is ideal for a diversity of hazardous applications.

The addition of HART® to this device enables sites using a 4-20mA output to gain value-added functionality without any additional infrastructural wiring costs, because HART® works by superimposing a digital signal on an existing 4-20 mA cable, meaning that no additional cabling is required.

With over 40 years experience in the design, manufacture, installation and maintenance of point infrared gas detection, Honeywell Analytics currently has a Worldwide installed base of over 100,000 infrared point Hydrocarbon gas detectors in a wide spectrum of applications from light industrial to the most demanding of offshore petrochemical environments.

Typical applications include environments that may suffer from the presence of catalytic bead poisons or inhibitors, or where there are harsh environmental conditions forcing increased time between routine maintenance, for example; offshore oil and gas platforms, floating production storage and offloading (FPSO) vessels, tankers, onshore oil and gas terminals, refineries, LNG / LPG bottling plants, gas compressor / metering stations, gas turbine power plants, refineries, solvent printing and coating plants.

Reduce your operational costs and gain enhanced device visibility Searchpoint Optima Plus is available with HART® over 4-20mA output. This communication aspect allows Searchpoint Optima Plus to deliver a wide range of added value benefits.

What is HART®?
HART® (Highway Addressable Remote Transducer) is a widely used digital communications protocol, which allows users to access live data, status indications and diagnostic information from intelligent field devices. It works by superimposing a digital signal on the existing analogue signal. A key benefit of HART® is the fact no additional field cabling is required, because HART® uses the device’s 4-20 mA signal cable.

HART® can also help to reduce costs in a number of ways. For example, it
eliminates the need for proprietary handheld devices; a field engineer can use a
single HART® handheld device to access any HART® enabled equipment on site.

The HART® signal can be interrogated from anywhere in the current loop, and
this means that users can access diagnostic information without going into the
field. This means that if maintenance is required, the scope of work is known
before the engineer goes to the device, potentially helping to reduce ongoing
maintenance costs.

Benefits of using HART®
• Access full information from Searchpoint Optima Plus, anywhere in the current
• No associated infrastructural costs, unlike some other communications protocols;
additional communication is achieved without the need for extra
• Save on set up costs by eliminating the need for proprietary handheld devices
• Save on long-term costs by enabling proactive not reactive maintenance
• Save a field engineer investigation trip - “know before you go”
