PBLTX Submersible Level Transmitters are manufactured for years of trouble free service in the harshest applications. Both measure the height of liquid above the position in the tank referenced to atmospheric pressure. The transmitter consists of a piezoresistive sensing element, encased in a 316 SS housing. Perfect for wastewater and slurry applications with features to protect the unit from these demanding applications. Large diameter 316 SS diaphragm seal is non-clogging and damage resistant to floating solids.The PBLTX is UL approved intrinsically safe for use in hazardous locations when used with proper barrier.Units come equipped with a 270-pound tensile strength shielded and vented cable. Ventilation tube in the cable automatically compensates for changes in atmospheric pressure above the tank. The vent is protected with a maintenance free filter eliminating particulate or water droplets from entering the transducer.Features:Durable cage design with large diameter 316 SS diaphragm seal that is non-clogging and damage resistant to floating solidsIncorporates lightning and surge protection utilizing dual arrestor technology, grounded to case, eliminating both power supply surges and lightning ground strike transientsMaintenance free filter eliminates particulate or water droplets from entering the transducerUL approved intrinsically safe on for use in hazardous locations when used with the proper barrier270 lb (122.5 kg) tensile strength shielded and vented cableExcellent chemical compatibilityNPT connection allows the unit to be rigidly installed in a pipe/conduit, or the addition of a A-625 hanging loop for attaching a chain for pulling out of the installationProduct Applications:WastewaterSludge pits, clarifiers, digestersAlum tanksChemical storage tanksOil tanksLime slurrySumpsReservoirs.
