B-DETECTION PLUS online gas measuring system for high-pressure applications
The online gas measurement system B-DETECTION PLUS monitors the quality of the compressed air: Measurement of CO, CO2, O2 as well as optional absolute humidity and oil (VOC)1. Automatic, constantly and extremely reliable.
By means of the B-CONTROL control, you can at any time observe compliance with the limit values of the breathing air standard DIN EN 12021: 20141.
In the case of an exceedance of the limit, the control system will shows an alarm on the display by means of an optical warning signal and switch off the system before air contaminated with pollutants enters the breathing air bottles.
An automatic flush valve (optional) ensures that the contaminated air is directed into the open air without interrupting the operation of the system if short-term limit values are exceeded.
With the new B-DETECTION PLUS gas measuring system, you now have a reliable partner at your side, available as version B-DETECTION PLUS i integrated into the compressor, and as stand-alone version B-DETECTION PLUS s. As an operator, you can enjoy the assurance of quality and legal compliance with BAUER's online gas measuring system. B-DETECTION systems can easily be retrofitted to existing BAUER compressors!
1 Humidity and oil measurement (VOC) optional. Oil measurement only on the basis of volatile hydrocarbons (VOCs). Sensor calibration based on isobutene.
All the information you need at your fingertips!
More features of breathing air and gas measuring systems for high-pressure compressors:
LEGAL CERTAINTY: When one or more limit values are exceeded, the compressor shuts down automatically. The system also runs a LiveCheck of all sensors before powering up. These safeguards ensure that breathing air cylinders are filled with nothing but pure, clean air at all times. All measurement
values can be logged using the B-CONTROL MICRO and exported to an SD card as Excel files. As the system operator, this provides you
with a high level of legal certainty.
PLUG AND PLAY: Supplied fully integrated with your compressor system, or as a standalone version for retrofitting:
the B-DETECTION AIRBOX includes a full range of all necessary accessories in a single unit for rapid, simple retrofitting to existing
SIMPLE SERVICE ACCESS: The integrated B-DETECTION PLUS i includes a connector for fast system testing, located under
the front panel. The front panel can be opened with a single movement to introduce the test gas through the connector provided.
SMARTPHONE INTERACTION: The new B-APP sends all current gas measurement data to your smartphone, enabling
you to check the quality of breathing air going into your cylinders at all times.
Suitable for retrofitting to any BAUER compressor
PureAir/PureAir GOLD certification possible
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.
B-DETECTION AIRBOX: Gas sampling unit (incl. in standard scope of supply)
The pressure reduction unit allows the measuring instrument to be connected to high-pressure lines. In addition, a solenoid valve is installed in order to prevent unnecessary load on the sensors and to avoid a return flow from the pressure vessels during periods of the compressor downtime.
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 CO2 content of 450 ppm or more in the intake air, we recommend using an AERO-GUARD CO2 absorber.
Automatic flashing valve
The venting device serves for the automatic flushing of compressor systems by the discharge of the compressed air into the environment. The automatic flushing valve can optionally be integrated into the B-DETECTION AIRBOX. If, during the start-up phase of the compressor, or during the compressor operation, the gas measurement values are exceeded, the compressor is switched off by the B-DETECTION PLUS and the compressed air is directed into the environment for a certain period of time via a bypass valve with muffler. If no improvement in the air values occurs after the defined period of time has elapsed, the compressor is switched off. Especially recommended for fully automated compressor operation.
