943 Vacuum Gauge Controller
Overview
The Series 943 displays pressure from 10-10 to 10-2 Torr using a high visibility LED display. Two types of analog output are standard for remote monitoring of pressure. An internal converter provides output that allows a simple log conversion from voltage to pressure over the entire operating range. A fast responding, buffered analog output is also provided. Front panel functions allow the user to disable the high voltage, as well as set a pressure at which the cold cathode will automatically turn off. This prevents the controller from displaying incorrect readings when the pressure goes above the operating range of the sensor.
- Wide pressure measurement range 10-10 to 10-2 Torr
- Digital LED display with set point status indicators
- Displays pressure in Torr or Pascal units
- Functions for disabling the high voltage, and set a pressure for the cold cathode to automatically turn off
