FEATURES/BENEFITS

•Slim design for tight applications with bullet nose, which protects the diaphragm from damage

• 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) on SBLT2 models

• Maintenance free lter eliminates particulate or water droplets from entering and damaging the transducer

• UL approved intrinsically safe on SBLTX models for use in hazardous locations when used with proper barrier

• Excellent chemical compatibility for wide application use

• NPT connection allows the unit to be rigidly installed in a pipe/conduit, or the addition of a A-625 hanging loop for attaching a

chain for pulling out of the installation

• Standard 72 hour lead time ensures minimal downtime

DESCRIPTIONAPPLICATIONS

• Air economizers

• Outdoor temperature and relative humidity reference for building systems

• Well monitoring

• Ground water monitoring

• Environmental remediation

• Surface water monitoring

• Down hole

• Water tanks

The Series SBLT2 & SBLTX Submersible Level Transmitters are manufactured for years of trouble free service. These series 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.
