Keyword: Pressure sensors

The EJA Series of pressure transmitters from Yokogawa UK is now being supplied with a guaranteed five-year stability specification, allowing users to operate a "fit and forget" policy even in the most demanding applications.

The ability to offer this guarantee results from the use of Yokogawa's DPharp(High Accuracy Resonant Pressure) technology, which uses a patented resonant silicon sensor to provide a combination of high linearity, repeatability, low hysteresis and unsurpassed reference accuracy of 0.01 per cent in real terms(Plate 4).

The signals produced by the sensor are measured directly by the transmitter's microprocessor, providing an entirely digital pressure measurement with long-term stability of 0.1 per cent for five years.

This new five-year specification is particularly significant as it is totally unconditional. This means that extended calibration intervals can be realised under the "real world" conditions found on most plants. Hence dramatic reductions in maintenance costs can be achieved over this period.
