SPX 5-Series: A Smart 4–20 mA Pressure Transmitter

The SPX 5-Series from Dynisco is an intelligent 4 to 20 mA pressure transmitter that features DynaLarity™, a Dynisco breakthrough that utilizes a sophisticated algorithm. This algorithm linearizes offsets caused by process effects on the sensor.

The SPX 5-Series is an all-welded construction developed for use in dangerous locations and comes with a wide range of process and electrical connections.

The SPX5 Series comes in various models, like SPX5342, SPX5343, SPX5344, SPX5390, SPX5391 and SPX5392.
