PBLT Submersible Level Transmitter is manufactured for years of trouble free service in the harshest applications. The PBLT measures the height of liquid above its position in the tank referenced to atmospheric pressure. The transmitter consists of a bonded foil, strain gauge, sensing element, encased in 316 SS housing. Perfect for wastewater and slurry applications with features to protect the unit from these demanding applications. Superior lightning and surge protection utilizing dual arrestor technology, grounded to case, eliminating both power supply surges and lightning ground strike transients. Large diameter 316 SS diaphragm seal is nonclogging and damage resistant to floating solids.

Comes equipped with a 220-pound tensile strength, shielded, vented, PE-TFE 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 moisture collection in the transducer. The vent filter is a much superior design to transmitters with desiccant tubes that need to be replaced and bladder bags that can throw off readings and add extra cost.
