The reduced internal volume allows for superior temperature dissipation. The 2098 is designed for limited space applications.  The 2198 can also be used where a diaphragm seal is required to be attached directly to the process.

Key Features:
  •  Effectively protects instruments from elevated temperatures
  • Siphon and sensing instrument mount directly to the process
  • 316L stainless steel, compatible with many process media
  • Used with gauges, switches, transducers and diaphragm seals
