Description: Piezo Vacuum Transducer, 0.1-1000 Torr, 0.125 in. NPT, RS232, 1 VDC per Decade, RJ45, IP40PART: 902B-31480OverviewThe 902B-32010 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 1/8 Inch NPT 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 0-10 VDC analog pressure output that is linear at 10 mV/Torr and can be interfaced to external analog equipment for pressure readout or close loop control. It has a male DB9 connector offering backward compatibility with the first generation 902. One mechanical relay is included for process control use, for example interlocking isolation valves and vacuum pumps. The SPDT relay includes both normally open and closed contacts and can be set to energize above or below a set point trip value. Many applications require continuous surveillance of system pressure and warning of atypical pressure levels. The flexible relay options of the 902B can provide warning to external safety logic in cases of abnormal pressure and loss of power. The 902B can be used as a standalone device or together with the PDR900 controller.Product Series Overview902B Absolute Piezo Vacuum TransducersTechnical SpecsDigital CommunicationRS232TypeVacuum TransducerSensorStainless steel enclosed Piezo (Absolute Pressure)DisplayNoInterfaceRS232/analogFitting Type0.125 in.
