nAPG - Digital Controllers

nAPG series Digital Active Pirani vacuum gauges are available in two models. The nAPG-M is the standard model and measures from atmosphere to 10-3 mbar, the nAPG-LC is a corrosion resistant version with measurement from atmosphere to 10-4 mbar.

Features and benefits

  • Wide-range supply voltage allows operation from 15 to 48 V DC.
  • Gauge naming allows user to store gauge identification data.
  • Sensor tube can be baked to 150°C.
  • Adjustable open collector set-point output for simple process control and interlocking.
  • NW16 flange for easy connection to vacuum systems - NW25 flange options on request
  • Serial communications based on a simple ASCII, low latency, query and command protocol that can operated in a point to point or multi-drop system with minimum overhead.
  • Remote calibration possible
  • Cable connections and gauge adjustment conveniently located, thereby minimising the space envelope required for access.
  • CSA and C/US approved, meets the safety requirements for electrical equipment for measurement.
  • RS485 or RS232 versions.
  • 9600 to 38400 baud, 8bits, 1 start bit, 1 stop bit, no parity
