The latest process automation sensors available from Baumer can help engineers working in the industry strike the right balance, but what about the often over looked consideration of long-term reliability and accuracy, especially over varying temperature conditions? For example, does your pressure transmitter consistently provide the desired accuracy at 50℃? Also considering that long-term drift will add further inaccuracies what about sensor performance about 60 months from commissioning? Maybe it's time to check the spec! Baumer's range of PFMH hygienic pressure transmitters are a good example of sensors which have been put to the test as a way of illustrating their reliability of performing satisfactorily over the long term. They were pitted against some other manufacturers' equivalent products to compare the full-scale accuracy (non-linearity, hysteresis, non-repeatability, zero-point and span) figures. The results indicated that the Baumer sensor retained its accuracy much better across the whole temperature range whereas others were almost +/- 3 accurate at only 50℃.
