Comments:
The LS600LDxx-FT sensor should be situated on the containment floor, the standard sensor function with the LS600LD Series with the float positioned to raise indicating a leak condition. If suspended above the containment floor by its cable, a fault/tamper alarm is generated. The manufacturer states that the LS600LDxx-FT sensor is available with Buna-n or stainless-steel float for monitoring in most petrochemical and chemical storage tank applications.
Note: The term “Non-Discriminating” refers to (-T) models that do not differentiate between alarm and tamper conditions, whereas “Discriminating” (-FT/-FLT) models do differentiate between alarm and tamper/wiring fault conditions.
