FPA4100 is a process photometer from Galvanic Applied Sciences connected to a measurement cell by a fiber optic bundle. Optical measurement allows the control cabinet to stay outside the hazardous area, while the measurement cell sits on the process side with a gas or liquid sample cell. The photometer calculates concentration by measuring the light absorption of the relevant component.

Available versions are IECEx (with sample cell), CSA Class 1 Div 2 (with sample cell), a CE-marked ATEX/IECEx configuration with gas sample cell, and a version supplied with a standard sample system for liquid applications. It is used for component tracking in gas processing and refinery streams.

FPA4100 features

  • Connection to the measurement cell by a fiber optic bundle
  • Gas or liquid sample cell option
  • ATEX/IECEx Zone 1 (Ex db ia IIB+H2 T4 Gb)
  • 6 pcs 4–20 mA outputs, 2 pcs 4–20 mA inputs
  • Modbus TCP/IP and 8 discrete inputs
  • Monochrome LCD and extendable keypad
