Series PBLTX Submersible Level Transducer
Specifications - Installation and Operating Instructions
By Dwyer
The Series PBLTX Submersible Level Transducer is manufactured for years of
trouble free service in the harshest applications. The PBLTX measures the height
of liquid above its position in the tank referenced to atmospheric pressure. The
transducer consists of a piezoresistive sensing element, encased in a 316 SS housing.
Perfect for wastewater and slurry applications with features to protect the unit from
these demanding applications. Large diameter 316 SS diaphragm seal is non-clogging
and damage resistant to floating solids.
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. The vent is protected with a maintenance free filter eliminating
particulate or water droplets from entering the transducer.
Intrinsic Safety Approval Classification
The PBLTX 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.
