Page 16: Operation
Allow for a stabilizing time of approx. 10 min. Once the gauge has been switched on, permanently leave it on irrespective of the pressure. 4.1 Measuring principle, The PBR260 consists of two separate measuring systems (hot cathode Bayard Alpert (BA) and Pirani). measuring behavior... - Page 17 Fig. 2 The bridge voltage U is a measure for the gas pressure and is further processed electronically (linearization, digitizing). Measurement range The PBR260 covers the measurement range 5×10 mbar … 1000 mbar. • The Pirani constantly monitors the pressure. •...
- Page 18 Defining the switching on/off The PBR260 has two definable switching on/off ranges with their corresponding range overlapping ranges. The switching on/off range is selected with the <P ↔ BA> switch and should be chosen in such a way that it is situated outside the process pressure range.

(5 mA emission current). Depending on the application, this function can be activated via a Single-, Dual- or MaxiGauge™ measurement and control unit, manually or automatically by the control system (e.g. PLC). The PBR260 automatically turns the bakeout off after 3 minutes, if the bakeout has not been stopped before. -
