Mercoid Series SBLT2 and SBLTX

Submersible Level Transmitter
Perfect for Ground Water and Wells, Lightning Protected or Intrinsically Safe
 
Mercoid SBLTSBLT2 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.

  • Excellent chemical compatibility
  • Lightning and surge protection on SBLT2 models
  • Maintenance free vent filter
  • UL approved intrinsically safe on SBLTX models
  • Slim design for tight applications
