DatenblattDynisco SPX 2-Series Smart Pressure Sensors
The Dynisco SPX 2-Series is a smart 4–20 mA pressure transmitter range for general-purpose pressure measurement in hazardous locations. The sensors feature an all-welded construction 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. Optional remote configuration via HART™ is available. Depending on the configuration, thermocouple or RTD versions are available for melt temperature measurement.
