MSA Series 47K Gas Sensors

MSA Series 47K Gas Sensors are designed to detect potentially hazardous concentrations of flammable gas and vapour in air.

The Series 47K Gas Sensors offer a cost effective range of sensor for detecting up to 100 % LEL detection, 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 virtually all applications in combustible gas detection.

MSA Series 47K gas 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.

Sensor Types

MSA sensors are available as standard in a stainless steel body.Series 47K-PRP: high resistance to atmospheres containing silicones,lead, sulphur compounds and halogenated hydrocarbons over a temperature range –40 °C to +90 °C

Series 47K-HT: to operate over a temperature range –40 °C to +160 °C
