PT4xx6 series high temperature melt pressure transducer(SAND)
Introduction
SAND PT4XXXB series melt pressure transmitters are ideal for the measurement of melt pressure in extrusion processes at temperatures up to 400℃. The PT4XXXB transmitters provide industry standard amplified signal designed to work with DCS and PLCs.Transmitters are available with 4~20mA, 0~20mA,0~10VDC or 0~5VDC outputs. The main characteristics are high accuracy and small zero and span shifts caused by changes in process temperatures.
Feature
- Better than 0.5% accuracy
- Standard diaphragm Inconel
- TiN or TiAIN coating available
- Small zero and span shifts caused by changes in process temperatures
