The MSA Gas Detector Series 47K is designed to continuously monitor the atmosphere for the presence of potentially explosive gas or vapour in air in the range 0 to 100% LEL. It is designed for use as an integral part of an MSA fixed gas detection system for the protection of industrial plant and workers. - Page 6 Failure to follow these warnings can result in serious personal injury or death. The only method of verifying the correct operation of the sensor is to carry out a span check using a known concentration of calibration gas in air. For response curves contact your national MSA office. Series 47K...

300mA for 47K-HT-PRP Vmax 10 V Operating life time 3 Years, in clean air, typically Storage life time 5 Years, in MSA container, typically Storage temperature range -20 °C to +40 °C** Operating temperature range PRP- sensor -25 °C to +55 °C Extended range *) -40 °C to +55 °C... - Page 9 2 Description *) Extended range: The sensor extended temperature range is greater than the maximum specified in EN 60079-29-1. It is therefore strongly recommended that if used above +55 °C or below -25 °C the sensor is calibrated at the operating temperature.

• The specified environmental conditions must be adhered to. • Position the height of the MSA Gas detector Series 47K according to the density of gas or vapour to be measured. • The proper installation location must be chosen to ensure that the sintered disc of the MSA Gas detector Series 47K is kept dry and dust-free. -
Page 11: Recommended Torque And Terminal Sizes
The maximum cable length depends on the maximum permissible load, the cross section of the conductor and the conductor material. The maximum permissible load [loop resistance] is 36 ohms for the MSA Control units SUPREMA [for MSA Control unit 9010/9020 refer to the control unit manual]. -
