DatasheetDynisco SPX 4-Series Smart Pressure Sensors
The Dynisco SPX 4-Series is a smart 4–20 mA pressure transmitter range for general-purpose pressure measurement in hazardous locations. The sensors are designed for use in hazardous areas and are available with a variety of process and electrical connections.
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.
