Product Description

The Level-Trac LT-310 is a remote level indication system, as described in ASME Section I, PG-60. The system may also be used as an alarm or trip device.

The Level-Trac Model-LT-310 water detection control unit can be used to drive up to six conductivity/resistance probes installed in a single column or separately. The unit features complete redundant and discrete channels, with two independent power supplies. Channel interaction can be entirely discrete, coincidental or based on 2 of 3 voting logic.

The LT-310 can be used as a direct replacement to external cage float switches, and offers solid state reliability with no moving parts. The Water Detection Unit is designed to be used with Model LT-500, LT-501 or LT-502 probe manifolds, or with single probe fixtures. Suggested applications are:

  • Traditional Water Gauge Columns at the Boiler Drum
  • Cold reheat & Extraction Steam Lines
  • Drain, Flash, and Dearator Levels
