P304i

The P304i is a fully programmable indicator with a single input configured for melt pressure measurement and the choice of wiring either strain gauge or amplified transducers to the unit. An optional second input provides an additional facility for differential pressure measurement if required. 

The update time for each channel is 50ms to respond to very fast processes. To provide full process measurement, the second input can be configured for either Thermocouple or RTD temperature measurement.

Three preconfigured and ready to use alarms are associated to the process to detect high and low pressure conditions. A flexible alarm strategy enables shutdown of extruder at dangerous pressure levels.
