902B Absolute Piezo Vacuum Transducers
Model: 902B-11280
Overview
Overview
The 902B-11280 Absolute Piezo Vacuum Transducer combines the pressure measurement technology of a MEMS-based Piezo sensor with a metal sealed stainless steel 316 diaphragm and integrated electronics. It features an IP40 rated enclosure, a size NW16 ISO-KF fitting and a RS232 digital communication interface for setup of transducer parameters and to provide real time pressure measurement. In addition, the 902B has a 16 bit 2-10 VDC LOG10 analog pressure output that can be interfaced to external analog equipment for pressure readout or close loop control. It has a RJ45/FCC68 8 pin connector. The 902B can be used as a standalone device or together with the PDR900 controller.
