Oil Check 500 - The monitoring system for permanent highly precise measurement of the vaporous residual oil content compressed air, nitrogen and gases
"Forced Pressure Variation" for long-term stable measurement results - Auto-calibration
Thanks to the innovative "Forced Pressure Variation" measuring method, the Oil Check 500 generates reference gas internally in different mass concentrations. With the help of this process, which is intellectually protected by CS INSTRUMENTS, components in the measurement signal caused by ageing or contamination, in particular long-term drifts, can be compensated. No wearing parts such as activated carbon filters are necessary for the generation of zero air. The result is a low-maintenance and long-term stable measurement

Features

Features

 N/A
  • Service friendly, no downtime
    The sensor unit can be replaced by the customer on site. This eliminates the need to return the entire unit for recalibration.
  • Process safety
    All functions / components are monitored internally. A complete function test report can be printed out via the service software.
  • On-site calibration
    Calibration can be carried out in the field using test gas cylinders. With the service software, a verification report (as-found data) and a calibration report (as-left data) can be generated.
  • Ideal for mobile measurement
    Compact device, easy sampling and quickly ready for measurement
  • Easy installation
    Air inlet / air outlet - sampling via PTFE hose or stainless steel pipe. Digital and analog interfaces as a standard. Connection via M12 plug
  • Service friendly - no downtime
    Loosen four screws - replace sensor unit. A complete function test is carried out at the push of a button. This means that the measurement can be continued almost without interruption.

Additional Information

N/A Measure compressed air quality according to ISO 8573
Residual Oil - Particles - Residual Moisture

Residual oil content measurement - Oil Check 500
For permanent and highly precise measurement of the vaporous oil content from 0.001 mg/m³ to 5 mg/m³. Due to the low detection limit of 0.001 mg/ m³, the compressed air quality class 1 (ISO 8573) can be monitored.

Particle counter PC 400
The highly precise, optical particle counter PC 400 measures particles from a size of 0.1 ?m and is therefore suitable for monitoring the compressed air quality class 1 (ISO 8573).

Moisture - dew point sensor FA 510
FA 510 measures the pressure dew point down to -112 Ftd. Also in this case the continuous measurement takes care that alert is triggered immediately if the compressed air dryer breaks down.

DS 500 - the intelligent chart recorder of the next generation
The centerpiece of compressed air quality measurement is the chart recorder DS 500. It measures and documents the measured data of the sensors for residual oil content, particles and moisture. The measured values are indicated on a 7" color screen.

The curve progressions from the beginning of the measurement can be viewed by an easy slide of the finger. The integrated data logger stores the measured values safely and reliably.

The threshold value can be freely entered for each measured parameter. 4 alarm relays are available for automatic alarm in case of threshold value exceedance.

Optionally DS 500 can be upgraded with up to 12 sensor inputs. For connection to a PLC DS 500 has an Ethernet interface as well as a RS 485 interface.

The communication is done via the Modbus protocol.
