Penberthy Series 1A Electronic Level Indication
|
 |
|
The Penberthy Series 1A single probe alarm system represents the latest advancement in electronic level indication.
Based on the conductivity probe technology now widely accepted in the industry, it was specially designed to meet increasing demand
for a reliable, cost effective means of sensing water in various applications. The probe can be mounted directly to the pressure vessel
or column. The probes are welded stainless steel HP and IP electrode with zirconia insulator (3000 psig @ saturation, up to 1200°F
[207 barg @ saturation, up to 649°C]) or threaded stainless steel LP electrode with Teflon® insulator (850 psig @ 525°F
[58 barg @ 274°C]). The Series 1A is a direct replacement for mechanical float switches. Local LED indication of water level provides
either redundant or primary visual verification.

Typical Applications
- Water Intrusion Protection for Turbines
- Sump Pump Protection
- Boiler Drum Level
- Equipment Drains (Desuperheaters, Control Valves, Sootblower Systems)
- Receiver Tanks (Condenser, Water Tank, Deaerator)
- Flash Tanks, Feedwater Heaters
- Steam Line Drain Pots
- High Pressure Systems (where float switches are economically not acceptable)
