S 120 is a precision measuring instrument for oil vapour concentration in compressed air and gases. Based on proven PID sensor technology, the S 120 offers portable periodic testing capability or full time 24/7 continuous monitoring of air quality. The standard version without display can interface with dataloggers or plant control systems through 4-20mA, RS-485 Modbus/RTU and SDI (SUTO Digital Interface) communications and has alarm indications through LED and relay output.
Selecting the S 120 with integral 5″ touchscreen display changes the unit from external sensor to a complete self-contained monitoring solution with graphical display, data logging and USB output. The simple menu driven screen allows easy operator access to all the data making it a powerful tool for mobile audits and plant diagnostic surveys. For continuous monitoring, the display provides operators at-a-glance simplicity to ensure oil levels are within tolerance and quick responses to changing contamination levels.
