For critical applications in industrial and research environments, the PTX 600 Series of two wire, 4 to 20 mA output pressure transmitters offers high levels of stability, versatility and measurement accuracy from a robust device.
GE’s well proven silicon technology has been developed to provide a miniature micro-achined diaphragm which is electrostatically bonded to a glass substrate and stitch bonded within a glass to metal seal assembly to provide exceptional thermal and stress isolation. The glass to metal seal is completed with an electron beam welded Hastelloy C276 isolation diaphragm and 316 stainless steel pressure port. The reduced internal volume of this assembly and advanced design features of the sensor significantly improves the stability and thermal performance of the transmitter.
The two-wire electronics incorporate power supply regulation and amplifier stages with independent zero and span controls, reverse polarity and over voltage protection with an RFI bulkhead providing feedthrough filters within the body tube assembly.
The PTX 600 Series features high accuracy, 0.08% FS Best Straight Line for the combined effects of non-linearity, hysteresis and repeatability, and to fully represent operating conditions, the thermal effects are expressed as a maximum change in output from the calibration at room temperature.
