Pirani Vacuum Gauge SP1

ULVAC

For more information on ULVAC products, purchase, and/or consideration, click here.

The sensor unit SP1 is an integrated pirani gauge consisting of the WP series sensor head and circuits, for the range of 3000 to 0.4Pa (22 to 3 x 10-3 torr/ 3 to 4 x 10-3mbar).

Features

  • Transducer type that saves cost and space
  • Easy replacement of sensor head
  • Platinum filament which has excellent corrosion resistance
  • Sensor heads you have been using (WP-01, 02, 03, 16) can be used as is.
  • Set-point output 2 points
  • Measurement value output DC 0 to 5V (non-linear)
  • Power supply voltage DC24V

Applications

  • Process control in the low vacuum range of vacuum equipment such as for semiconductor, optics and electronic parts manufacturing.
  • Process control in the low vacuum range for industrial equipment such as vacuum furnaces, etc.
  • Process control in the low pressure range for vacuum systems with multiple process chambers such as in-line sputtering and single wafer processing equipment.
