DatasheetDynisco SPX 5-Series Smart Pressure Sensors
The Dynisco SPX 5-Series is a smart 4–20 mA pressure transmitter range for general-purpose pressure measurement in hazardous locations. The sensors use an advanced algorithm to linearize offset effects caused by process conditions, providing precise and repeatable pressure measurements in demanding industrial applications.
These amplified transmitters eliminate the need for external signal conditioning and can be connected directly to DCS, PLC, computer and other high-level control systems. All models can be interface-configured, with optional remote configuration via HART™. Optional thermocouple or RTD configurations are available for melt temperature measurement.
