Abstract:
A Polish research institute conducts research on measurements of physical parameters of atmosphere, including barometric pressure. For this purpose a precise, portable, digital absolute pressure meter and data logger of a high resolution, approved for operation in explosive atmospheres, has been made. Due to an extended range it can be applied in deep mines or caves. They look for solutions in the field of precise absolute pressure measurements and offer their expertise.

Description:
Portable, digital absolute pressure meter and data logger μBAR was designed by a Polish research institute for measurements of absolute pressure of air in range of 800 to 1300 hPa. Workings of underground mines were the original scope of application. The device is intrinsically safe, having a category Exia I. The device measures and records pressure with a large accuracy of +/- 0.02% FS. It can be applied for both instantaneous measurements, performed by ventilation services of mines, and research experiments. Microprocessor controlling operation of the device performs as a data logger. This enables storage of results in internal memory and easy transmission of data to external computers. The capacity of the memory allows to store up to 10833 measurements samples with a period of 0.5 to 3600 seconds. The internal real-time clock may be set from an external computer, which allows for synchronisation of several barometers. It is also possible to store an instantaneous measurement with a comment containing a date, time and identifier of the measurement. Resolution of measurement is 1 Pa. This allows for precise pressure survey. The long-term stability of indications is better than 0.005% FS in 24 hours. Rechargeable battery power supply guarantees 18 hours of continuous operation. Stationary or non-intrinsically-safe versions are optional.


Innovative Aspects:
Capability of:
• Precise measurements and records of barometric pressure with a high accuracy on large depths under the Earth surface.
• Intrinsically safe – can operate in explosive atmospheres i.e. methane
• Synchronisation of timers of several barometers enables pressure distribution sampling

Main Advantages:
• Very good metrological parameters
• Applicable in difficult environmental conditions i.e. mines or caves and explosive atmospheres
• Internal, programmable timer for remote, delayed recordings
• Professional quality of manufacturing
• Customisable to specific demands
