Varian SenTorr BA2 LR88590 Vacuum Gauge Controller

Model No. LR88590

Varian’s senTorr Gauge Controller is a complete, half-rack vacuum gauge controller that offers continuous, reliable pressure measurement from rough to high vacuum. The controller comes completely configured from the factory to operate this gauge tube configuration: BA2 Two Thermocouples and one Bayard-Alpert gauge tube.

The senTorr Gauge Controller features one digital display per gauge tube. The displays are LED-driven providing clear and sharp pressure readings. The front panel keypad has practical lockout features that protect against unauthorized parameter inputs. Analog outputs and remote capabilities are located on the back panel. The external remote input controls turnon or turnoff of high-vacuum gauge emission.

Options include set points and RS232 or RS485/422 communication ability. Resistive (I2R) degas is an option on Bayard-Alpert models, E-beam degas on the UHV models. The set point option includes four set points, one for each gauge tube plus an additional set point that can be assigned to any one of the three gauge tubes.

The senTorr offers an extraordinary amount of gauging and programming capability while still remaining easy to use. The operator can access all of the instrument’s functions and parameters through the front panel keypad or the optional serial link.
