Stability guaranteed

The EJA Series of pressure transmitters from Yokogawa UK is now being supplied with a guaranteed 5-year stability specification.

The EJA Series of pressure transmitters from Yokogawa UK is now being supplied with a guaranteed 5-year stability specification, allowing users to operate a fit and forget policy even in the most demanding applications, says the company.

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 reference accuracy of 0.01% in real terms.

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% for five years.
