Series SBLT2 & SBLTX Submersible Level Transmitter

Perfect for Ground Water and Wells, Lightning Protected or Intrinsically Safe

SBLT2 and SBLTX 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. Bullet nose design protects the diaphragm from damage.

The SBLT2 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 SBLTX 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.

Questions

Question
Is it safe to soak an MBLT level transmitter in vinegar or muratic acid to remove accumulated scale deposits?
Answer
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.
Question
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?
Answer
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.
