B-Detection

SKU: B-Detection

In addition to continuous stationary monitoring of CO2, CO and O2 in the compressor, this device uses a pressure reducer to allow mobile analysis of breathing air on site. There is also the option of measuring the dew point and thereby displaying the absolute humidity in accordance with DIN EN 12021:2014.

Packaged inside a sturdy plastic­ case and equipped with a powerful battery for standalone operation.

If the measuring system is used for continuous measurement with a compressor with B-CONTROL, the measured values can be saved with the B-CONTROL data logger and downloaded to a computer easily via SD card (B-CONTROL MICRO) or USB stick (B-CONTROL II) for output in Excel.

More features of breathing air and gas measuring systems for high-pressure compressors:

  • External outputs and alarm output are watertight to allow outdoor operation in wet or humid conditions
  • Alarm and error messages when predefined limit values as per DIN EN 12021:2014¹ are exceeded
  • Operation and charging require standard 110/220 V power source
  • Designed for connection to 12/24 V on-board electrical systems
  • PureAir/PureAir GOLD Certification possible (for continuous operation)

¹ No residual oil measurement, compliance monitoring of humidity limit values by choosing absolute humidity measurement only.

  • Humidification distance – Electrochemical sensors (CO and O2) require a certain level of gas quality in terms of humidity, pressure and temperature to ensure they function to their full potential. In fact, if the gas treatment is incorrect or even lacking, this can significantly reduce the service life of the sensors. For this reason, if the B-DETECTION is in continual use for over an hour, BAUER recommends the use of an optional humidity membrane to ensure the sensors are able to run to maximum capacity.
  • Ambient air pump – An additional pump installed within the measuring instrument makes it possible to check the gas composition of the intake air. For an overall CO2content of 430 ppm or more in the intake air, we recommend using an AERO-GUARD CO2
  • CO2flushing valve – The CO2 concentration in the compressed breathing air within the filter container usually corresponds to the concentration in the ambient air. These values may differ when inserting new filter cartridges (as CO2 is adsorbed from the air by the molecular sieve for a short time) and in the event of a pressure drop within the filter container. If the pressure should drop – which typically happens when switching off each compressor – the CO2 content in the filter container increases. When switching the compressor back on, the accumulated air with its increased CO2 content is then flushed out of the filter container. To avoid increased CO2 values in the compressed breathing air, we recommend flushing the compressor unit – i.e. draining the compressed air to the outside by opening the flushing valve – for approximately 2 minutes before connecting and filling the compressed air cylinders. As not all high-pressure compressors have a flushing valve for discharging increased CO2 values included in the standard scope of delivery, BAUER offers the option to retrofit this type of equipment.
  • Pressure reduction unit – The pressure reduction unit allows the measuring instrument to be connected to high-pressure lines. Depending on the control type of the high-pressure compressor, the option of a suitable pressure reduction unit is also available to limit the system inlet pressure with a solenoid valve (for systems with B-CONTROL) or ball valve (hard-wired control). In the case of the solenoid valve option, this is controlled by the compressor unit.
  • Automatic bleed unit – The bleed unit allows compressor units to flush automatically by redirecting compressed air into the surrounding atmosphere. If the CO2values in the compressed air are too high during the compressor start phase, B-DETECTION is suppressed from switching off the compressor and the compressed air is routed into the surrounding atmosphere via a silencer for a fixed period. If there is still no improvement in the air values several minutes, the compressor then switches off.
