Series PBLT2 & PBLTX Submersible Level Transmitter
Perfect for Sludge and Slurries, Lightning Protected, Intrinsically Safe
PBLT2 and 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 PBLT2 incorporates lightning and surge protection utilizing dual arrestor technology, grounded to case, eliminating both power supply surges and lightning ground strike transients (surge protection is not guaranteed and is not covered by warranty). 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.

Product Data Sheet
- Is it safe to soak an MBLT level transmitter in vinegar or muratic acid to remove accumulated scale deposits?
- Feel free to use whatever cleaning chemicals you like to remove accumulated scale deposits as long as the chemicals are compatible with the unit’s wetted materials as specified in our published literature.
- Our client has an MBLT pressure transmitter that appears to be malfunctioning due to scale buildup. The transmitter is installed to measure leachate level in a one-year old municipal sanitary landfill. What can we use to remove scale from the transmitter without damaging the transmitter?
- If the issue is due to build-up which consequently plugs the small sensing holes, you might take a look at our PBLT2 or FBLT series. They are both more rugged and designed for sludge and slurries, whereas the MBLT and SBLT2 are better suited for cleaner applications such as ground water and wells.
