Melting pressure indicator ASCON

The J5 provides measurement of melt pressure and other process variables. The J5 features a large 5 digit display that can operate in either green or red or change color in case of alarm. The J5 is configurable from the front, or from a PC with a software tool. The main input is for Strain Gauge or linear DC voltage/current with square root extraction or with a 16 segment linearizer. The second input with DC voltage or current is suited to temperature indication and signal conditioning (min, max, average, ratio, etc.) when combined with the main input. The J5 has 3 digital inputs independently configurable for alarms, display and calibration handling. Up to four alarms with ISA-A acknowledge are available as well as a retransmission output and Modbus RS485 comms. The J5 has three levels of password protection and the front panel is IP65. The strain gauge bridge of the melt pressure or load cell transducer can be powered by an internally regulated 5 or 10Vdc. The reliability of the strain gauge is monitored continuously. A front panel calibration routine is provided to automatically remove zero and span offsets. The automatic calibration can also be activated by using front keys, one of the three digital inputs, or over serial comms. Tare function for load cells is provided.
