Honeywell Sensepoint gas detector ordering method

Honeywell Sensepoint gas detector ordering method

Product Overview

Honeywell's Sensepoint series of gas detectors covers combustible gas, toxic gas, and oxygen detectors, providing high-quality, low-cost solutions for industrial gas monitoring needs. They are suitable for new construction and renovation projects and demonstrate high performance and reliability in a variety of demanding applications.

Core advantage: Adopting mature sensor technology such as Surecell ™  Electrochemical sensors, anti poisoning catalytic beads, fast and reliable response, with a typical service life of 2-5 years for sensors; Certified by ATEX/IECEx, in compliance with the latest standards, with hazardous area use permit and corresponding performance; The protection level reaches IP65/67, which can be used in harsh environments; The factory preset operation is easy to replace, requires less training, and also provides various accessories such as weather caps, flow adapters, etc.

Adaptability: Suitable Ex d or Ex e certified junction boxes should be used to install in potentially explosive environments, with output that meets industry standards and can be connected to Honeywell Analytics controllers or third-party DCS/PLC systems.

Characteristics of different types of detectors

Combustible gas detector: available in% LEL or PPM detection range versions, providing industry standard mV bridge output, with a typical lifespan of over 5 years, and can be replaced directly upon expiration.

Toxic gas detector: pre calibrated, easy to install, providing industry standard 2-wire 4-20mA loop output; The user connection is Ex d type, and the front-end intrinsic safety (IS) design allows for live replacement of replaceable sensors without sintering, with a fast response speed to "viscous" gases such as chlorine and ammonia.

Installation details

Dimensions: There are differences in some dimensions between combustible gas (% LEL or PPM version) and toxic or oxygen versions, such as 90mm and 74mm for combustible gas detectors, and 56mm for toxic gas detectors.

Junction box and installation: Use appropriate Ex d or Ex e junction boxes for installation. The standard junction box provided by Honeywell Analytics includes a grounding continuity board to enhance RFI protection; The detector has multiple installation thread sizes to choose from to match local preferences, and can be used in conjunction with Honeywell Analytics' various controllers or third-party control devices that accept its industry standard output signals.

Electrical connection: Different types of detectors have different wiring methods. The combustible gas% LEL version uses a 3-wire mV bridge circuit, the toxic or oxygen version uses a 2-wire 4-20mA (Sink) system, and the combustible gas PPM version uses a 3-wire mV bridge circuit.

Technical specifications

Covering multiple gases and detection ranges, detectors corresponding to different gases have differences in working temperature, working humidity, storage conditions, working pressure, preheating time, response time, power supply, signal output, linearity, working life, storage life, stability, weight, construction materials, protection level, certification details, etc.

For example, the working temperature of combustible gas 0-100% LEL version is -40 to+80 ° C (high temperature version -55 to+150 ° C), and the signal output is mV bridge; Hydrogen sulfide (H ₂ S) 20/50/100ppm version operates at temperatures ranging from -25 to+50 ° C, with a typical lifespan of 18 months.

In terms of certification, combustible gas detectors and toxic gas detectors comply with different ATEX/IECEx standards, and some also have Russian GOST certification and comply with relevant CE standards.
