Instrumentation
Instrument Regulators
IRA-3T (Output Range 0-100 psig)
- Diaphragm design for increased low pressure
  sensitivity
- Provides a regulated sample supply to
  chromatographs, H2S analyzers,
  gravitometers. calorimeters, moisture
  analyzers, and other on line analyzing
  equipment
- Inhibits carry over of free liquids into
  instrument supply system
- Patented Automatic insertion Device allows
  insertion and removal of probe from a high
  pressure pipeline through a full open isolation
  valve without pipeline shutdown (specify
  insertion length)
- 1" NPT connection standard, larger sizes
  available
- Flanged connection available up to 900
  ANSI in RF, RTJ, etc.
