For best accuracy as well as enduring stability, The s 120 sensor applies an automatic calibration. Sensor contaminations and sensor life time are monitored and indicated to the user. An over range detection removes the sampling air from thesensor to safeguard it against contamination. The simple installation and outstanding performance makes thes 120 the ideal choice when oil vapor content must be be measured and monitored. Features measures oil vapor contents in pressurized atmosphere and other gases can can serve as permanent or in portable applications measures down to 0. 003 mg/m easy connection through sampling hose and quick connect signals produced 4 . .. 20 ma, RS-485 protocol with Modbus RTU relay control switch disabled pid sensor for highest accuracy service and alarm indication through led linkable to automotive displays and data loggers for well asthird Event management solutions with five touch screens and a data logging feature built into control units and displays option
