MSA remote sensors, Series 47K, are designed to detect potentially hazardous air concentrations of flammable gas and vapour.

A cost-effective range of sensors for detecting up to 100 % LEL, including Poison Resistant and High Temperature versions.

Series 47K sensors are available with either Ex d – 3/4″ NPT or Ex e–M25 junction boxes.

A complete range of accessories for calibration, environmental protection, sampling and duct mounting makes it suitable for virall combustible gas detection applicationseries 47K sensors used in combination with MSA Controllers fully meet the requirements of ATEX Directive 2014/34/EU, including performance, and being SIL 2 capable they can be used as part of a safety related system.

Features

• 0–100% LEL.
