Up to now, users were forced to undergo time consuming and costly preparation of mounting bores for different maximum pressures, since no sensors with maximum pressures of more than 6000 bars were available being small enough to fit into the typically existing M10 threads. A lot of engineering power was invested to reduce the dimensions according to our customer requirements. Finally, all sensors have an M10 thread and enable mounting within existing boreholes. This allows for measurements of different maximum pressures up to 8000 bar, ideally within one existing barrel and mounting position, helping to save time, money and to facilitate the interpretation of results.
For many applications at lower pressures the charge output of the so far used equipment was unsatisfactory. The signal to noise ratio of measurements dropped and partly led to poor reproducibilities and data which had to be carefully interpreted. The new sensors are equipped with GaPO4 crystals that show the well known reliable behavior of quartz but at a higher charge output. For the 2000 bar sensor this gives an improvement of about 200% to the state of the art, finally leading to a significant improvement in data quality. The 6000 and 8000 bar sensors also profit from that by a significantly improved signal to noise ratio.
All members of the novel sensor family have an excellent linearity, compared to the types used today they are improved by a factor of two. Additionally, the batch to batch variation between single sensors has been reduced. Both features contribute to an easy comparison of data being collected with different sensors; consequently time-consuming cross references can be reduced.
