Page 13: Determination Of The Installation Point
• The sensor is for indoor use only! At an outdoor installation, the sensor must be protected from solar radiation and rain. • It is strongly recommend not to install S211 / S215 / S220 permanently in wet environment, which usually exists right after a compressor outlet. -
Page 14: Installation
The flowing air or gas must pass the sensor tip for a proper measurement. This can be realized with a measurement chamber. For an installation without the measuring chamber, you must insert the sensor to the required depth, as described in section 8.2. S211 / S215 / S220... -
Page 15: Installation Procedure
• Please check the size of the nozzle and make sure not less than 1/3 of the sensor tip is inside of the pipe. • The inner thread must be G 1/2”. S211 / S215 / S220... - Page 16 An upside down installation is not permitted. Removal of the sensor Unscrew the sensor off the measurement chamber or from the nozzle. Please make sure that the system is pressure-less before the sensor is removed. S211 / S215 / S220...
