1198 Finned Siphon

The Ashcroft® type 1198 Finned Siphon protects pressure instruments from the effects of elevated temperatures. A reduced orifice decreases the volume of the process in the siphon allowing efficient heat transfer between the process and the siphon. The siphon's metallic fins maximize exposure to the ambient temperature for effective dissipation.

Key Features:

• Effectively protects instruments from elevated temperatures
• Siphon and sensing instrument mount directly to the process
  
• Built-in dampening mechanism combats process pulsation
• Compatible with many process media
• Use with gauges, switches, transducers and diaphragm seals

Specifications:

• 316L stainless steel (other material avaiable upon request)
• Process / Instrument Connections: 1/4" or 1/2" NPT
