Dwyer SBLTX - Manual

Series SBLTX Submersible Level Transducer
Specifications - Installation and Operating Instructions
Bulletin L-37
The SBLTX Submersible Level Transducer is manufac-
tured for years of trouble free service. The transducer con-
sists of a piezoresistive sensing element, encased in a 316
SS housing. Bullet nose design protects diaphragm from
damage. Comes equipped with a 270-pound tensile strength,
shielded, vented cable. Ventilation tube in the cable automat-
ically compensates for changes in atmospheric pressure
above the tank.
