SPX series

SPX3343 Smart Pressure Sensor Series

SPX3343

The SPX-T (3-Series) is a smart 4-20mA pressure transmitter that includes Temperature Compensation and DynaLarity™, a Dynisco innovation. The SPX-T delivers the best spec performance in the line. Temperature Compensation is based on an RTD measurement that compensates for temperature variations which reduces temperature-related drift and increases accuracy. No need to re-zero for temperature changes after installation. DynaLarity uses an advanced algorithm that will linearize offsets due to process effects on the sensor. Combined Temperature Compensation and DynaLarity reduces temperature-related drift by as much as 80% and improves accuracy by more than 60% over other sensors. Process temperature output is available (RTD or 4-20mA). HART communication is standard. The SPX 3-Series is an all-welded construction designed for use in hazardous locations and are available with a variety of different process and electrical connections. These amplified transmitters eliminate the need for external signal conditioning. All models can interface directly with distributed control systems, PLC's, computers, and similar high level control devices

All sensors in this series can be configured according to your needs. Contact us, we will be happy to help you.
