Series SBLTX Submersible Level Transducer
Specifications - Installation and Operating Instructions
Bulletin L-37
The SBLTX Submersible Level Transducer
is manufactured for years of trouble free
service. The transducer consists 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
automatically compensates for changes in atmospheric pressure above the tank.
Intrinsic Safety Approval Classification
The SBLTX is UL listed for use in Hazardous (Classified) Locations. The protection
method is by Intrinsic Safety, “ia”. It was investigated by UL under UL Standard 913
8th Edition, CAN/CSA C22.2 No. 60079-0:15 and CAN/CSA C22.2 No. 60079-11:14.
