DESIGN FEATURES

The OBE-2002 is a module which provides the user with a small, low-cost method of accurate vacuum measurement over a wide range of pressure. The OBE-2002 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-2002
electronics module is available with many different types of signal output options for the user.

OBE-2002 is ideal for applications that require accuracy without the expense of costly capacitance manometers and a wide measurement range without multiple gauges.

The analogue version generates dual 10 VDC output voltages which are linear with pressure. The first linear output has a 1000 Torr full scale value; the second output is 1000 mTorr full scale. This version can be provided with an optional 4-digit LED display. The display provides floating-point
pressure readout and is easily visible from several yards.

A communication version provides RS232 or RS485 output to the user’s PC. A simple set of commands allows the user to have full access to the 2002 sensor tube. The RS485 configuration is capable of communication over several hundred feet with addressing. This version can also be
ordered with optional display.
