LS600LDxx Leak Sensor

Product Description

The LS600-LD float-actuated leak sensor provides secondary containment leak detection for above ground and underground storage tank applications. The sensor assembly may be suspended at the desired point of actuation via the sensor cable and
compression fitting, or allowed to rest at the bottom of the containment area being monitored. The compact size and favorable
displacement properties of the LS600-LD make it ideal for monitoring shallow liquid levels. The LS600-LD Leak Switch is available with a Buna N or stainless steel float for monitoring in most petrochemical and chemical storage tank applications. The
LS600-LD optionally supports Pneumercator’s FAULT-DETECT supervised wiring technology, which automatically detects field wiring faults when connected with a TMS series controller
