SUTO's S120 oil residues sensor (oil vapour) can monitor the residues of compressed air or gas on a long-term or sampling basis,simplely and conveniently installation, having good performance.An oil-free air compressor is hard to attain.In many industries, the monitoring of oil content is necessary in order to avoid product pollution and damage people's health.The S120 makes such monitoring affordable and reliable.The sensor provides self-calibration for better accuracy and maximum stability.The sensor's pollution level and life time will be monitored and displayed to the user.If detected beyond the range of use, the sensor blocks the sampled gas to prevent contamination.
○ Measuring the residual oil content of compressed air and gas
○ Used in both long - term and portable measurement applications
○ As low as 0.003 mg/m³ can measured
○ Quick connection through the sample tube , easy to install
○ Programmable alarm set point with device turn off option
○ Voltage/polarity display, each through output signal: - 4 ... 20 mA
- RS-485,Modbus RTU
- Relay switch (normally on)
○ Optical ion sensor, high accuracy
○ Use LED lights to indicate maintenance or alarm status
○ Can be connected to the SUTO monitor and data recorder, or to a third party monitor or controller
○ 5-inch touch screen and data recording (optional)
