S120 is a precision measuring instrument for oil vapour concentration in compressed air and gases. Based on proven PID sensor technology, the S120 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 S120 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.
