DYNISCO SPX-T melt pressure transmitters

The DYNISCO SPX-T (3-Series) melt pressure transmitters with a 4–20 mA output offer DYNISCO’s DynaLarity feature that delivers accurate pressure measurement under high processing temperatures, and greatly improves pressure measurement errors even at low pressure.

The SPX-T melt pressure transmitter is capable of eliminating thermal zero shift, a common problem with melt pressure transmitters, where their measured pressure output varies at low pressure between a cold extruder, and elevated running temperatures once operational.

Temperature compensation is based on an internal RTD measurement that compensates for temperature variations, which in turn reduces temperature-related drift and increases accuracy, so that there is no need to re-zero for temperature changes after installation.

The SPX-T uses an advanced algorithm that will linearise offsets due to process effects on the sensor.

The combination of temperature compensation and DynaLarity is said to reduce temperature-related drift by as much as 80% and improve accuracy by more than 60% over other sensors.

Process pressure as well as temperature output is standard along with support for HART communication.

All SPX 3-Series models offer ±0.15% accuracy and are available in a wide selection of pressure ranges. They have a turndown ration of 6:1 and are remotely configurable via HART, and configurations are available for use in hazardous locations.
