Honeywell Searchpoint Optima Plus Infrared Point Gas Detector

Honeywell Searchpoint Optima Plus Infrared Point Gas Detector

Product Overview

Searchpoint Optima Plus is an advanced infrared point type hydrocarbon gas detector suitable for potentially explosive environments. With its infrared detection principle, it has the characteristics of fast response, fault safe operation, etc., which can ensure factory compliance, personnel safety, and maximum uptime of the production process. Compared with traditional electrocatalytic gas detectors, it can reduce daily maintenance and overall cost of ownership.

Global application foundation: Based on over 40 years of design, manufacturing, installation, and maintenance experience, more than 100000 infrared point type hydrocarbon gas detectors have been installed worldwide, with a wide range of application scenarios, from light industry to demanding offshore petrochemical environments.

Typical applications: including environments where catalytic bead toxins or inhibitors may exist, as well as harsh environments that require extended daily maintenance intervals, such as offshore oil and gas platforms, floating production storage and offloading (FPSO) vessels, oil tankers, onshore oil and gas terminals, refineries, LNG/LPG bottling plants, etc.

Detectable gases: Over 100 types of gases and vapors can be detected. For specific lists, please consult the customer support team or local distributors.

Core Technologies and Components

Optical module: The 4-channel (dual compensation) optical module is the core, which not only compensates for external environmental changes like the 2-channel design, but also compensates for long-term component drift such as infrared light sources and detectors, providing the most stable optical design.

Microprocessor: controls the operation of the detector, and its signal processing and algorithms reach new heights in false alarm elimination, providing the highest level of operational integrity.

Heating optical system and dynamic heating control: The heated optical components are monitored by intelligent electronic devices, which have energy-saving functions and can eliminate condensation accumulation.

Remote gas injection unit: The optional remote gas injection unit is installed in the optical path at the factory and can remotely inject functional test gases to verify detector performance.

Sampling system and accessories

Remote gas sampling system: For remote or difficult to access locations, flow enclosures can be equipped and integrated into the gas sampling system, providing single point and multi-point systems suitable for hazardous and non hazardous areas.

Main accessories:

Sunshade/Rain Protection: Standard multifunctional accessories to protect the detector from extreme environmental impacts and ensure reliable operation.

Storm Barrier: Optional barrier to reduce wind chill, salt, and dust accumulation in high wind exposure applications.

Standard weather protection: Standard equipment, achieving the best balance between waterproof/dustproof and response speed.

Dust barrier: Installed inside the standard weather protection, it additionally prevents dust and pollutants from entering the light path.

Gas injection cover: can confirm the performance of the detector, closely matched with standard weather protection, and can be installed without special tools.

Calibration cap: used to achieve accurate calibration of detectors.

XNX Universal Transmitter: Provides local display and non-invasive access through magnetic switches, with HART capability ®  Communication output and optional Modbus, Foundation fieldbus, or relays.

HALO junction box: Ex e certified junction box with LED halo for local visual status indication, optional non-invasive HART ®  Interface.

Pipeline installation kit: Installation plate device, which can install the detector in the pipeline/ventilation system without removing it from the pipeline system for functional gas testing.

On site inquiry tool: The multifunctional handheld interrogator (SHC-1) is a certified debugging/maintenance tool for hazardous areas, which can reconfigure detectors to adapt to different gases and perform fault diagnosis. It can also be used for raw Searchpoint Optima and Searchline Excel (open circuit gas detectors), reducing operator training.

Terminal/Installation Accessories: Provide a full range of hazardous area certified Ex e and Ex d junction boxes, as well as SHC-1 protective devices, to provide electrical protection for SHC-1 when using conventional terminal enclosures.

HART ®  communication protocol

Protocol advantage: HART ® Highway Addressable Remote Transformer is a widely used digital communication protocol that allows users to obtain real-time data, status indicators, and diagnostic information from smart field devices by superimposing digital signals on existing analog signals, without the need for additional field wiring, helping to reduce costs. If dedicated handheld devices are not required, engineers can use a single HART ®  Handheld devices access all HART devices on site ®  Enable the device and query HART at any position in the current loop ®  Signal, diagnostic information can be obtained without the need to go to the site, reducing maintenance costs.

The detector supports functions such as viewing gas readings, configuration, and diagnostic information, conducting collision testing, mA loop calibration, gas calibration, simulating alarms, faults, or warnings, setting device tags, IDs, and descriptions, viewing activity warning/fault and event history, forcing mA output to a specific level for testing, configuring real-time clock, configuring suppression, warning, and over range levels, configuring alarm thresholds, changing target gases, and password protected access.
