Description Specifications Literature Description The OBE is system-mounted gauge which provides the user with a low-cost method of accurate vacuum measurement over a wide range of pressure. The OBE uses the same rugged HPM-2002S tube as the award-winning Model 2002. The module contains all of the performance features of the Model 2002 dual sensor instrument in a compact configuration. The OBE electronics module is available with many different types of signal output options for the user.OBE is ideal for applications that require accuracy without the expense of costly capacitance manometers and a wide measurement range without multiple gauges.The OBE can be configured to provide one of several different output options including Dual 0-10 VDC, RS232, RS485, Dual 4-20 mA, and DeviceNetTM. All output options, except DeviceNetTM, include a 4-digit LED display. The display provides floating-point pressure readout which is easily visible from several meters. The 0-10 VDC analog output version generates two outputs which are linear with pressure. The first output has a 1024 Torr full scale value; the second output has a 1000 mTorr full scale value.Features:Low-Cost Electronics ModuleWide Dynamic Range (1x10-4 - 1000 Torr)Combined Sensors in a Single TubeInput Voltage (12-30 VDC)15-pin High-Density D-sub ConnectorBright 4-Digit (green) LED DisplayOptional OutputsDual 0-10VRS232/485Dual 4-20 mADeviceNetTMApplications:LoadlockPlasma CoatingOEM EquipmentWide Range Vacuum ControlsRefrigeration State of California Proposition 65 WARNINGCancer and Reproductive Harm - www.P65Warnings.ca.gov.
