Overview MBLTFBLTSBLTPBLT

Technology Measure the height of liquid above the position in the tank referenced to atmospheric pressure Pressure on sensor can be related to height of liquid. Piezoresistive sensing element, encased in a 316 SS housing Piezoresistive – describes a material whose resistance changes as a function of mechanical strain applied

FBLT Introduction FBLT Submersible Level Transmitter Flush Diaphragm Design Purchase by Level Range, Cable Type and Length

FBLT Specifications Wetted Materials: Body: 316 SS; Cable: Polyether polyurethane or ETFE; Diaphragm: PTFE coated FKM Accuracy: ±0.25% FS Electrical Protection: Surge/lightning protected per EN , Class 5

FBLT Product Features Flush, PTFE coated diaphragm Low profile narrow design for tight applications such as through pipe installations Non-clogging/non-fouling for particulates and sludge PTFE is non-stick for no buildup on the sensor Gel fill will not leak even with small holes in the diaphragm. Competitors use oil.
