U-GAGE® Chemically Resistant Ultrasonic Sensors
Teflon®-protected sensors for harsh environments
Features
• Available option for all Banner QT50U and T30U..B models.
• Factory-installed Teflon flange and film coating bonded over the transducer provide
protection from harsh environments.
• The flange is sealed to the sensor face using a Viton® o-ring; other o-ring materials
may be specified (contact factory).
• Performance specifications for these models are identical to those of corresponding
standard models, with the exception of reduced sensing range (see Performance
Curves below).
• Sensor dimensions and mounting vary somewhat from corresponding standard
models (see dimensions on reverse).

Models
Add suffix “-CRFV” to the model number of any standard QT50U or T30U..B model
sensor to get this option. For example: QT50ULBQ6-CRFV or T30UINB-CRFV. Consult
factory for information on T30U..A models.

WARRANTY: Banner Engineering Corp. warrants its products to be free from defects for
one year. Banner Engineering Corp. will repair or replace, free of charge, any product of its
manufacture found to be defective at the time it is returned to the factory during the warranty
period. This warranty does not cover damage or liability for the improper application of
Banner products. This warranty is in lieu of any other warranty either expressed or implied.
Installation
The sensor may be threaded directly into
the side of a tank (see dimensions for hole
diameter and thread specifications), or into
a non-threaded hole, using the included
threaded nut.
For a non-threaded hole, install an o-ring
onto the flange, and insert the flange
completely into the hole until the sensor
front surface is against the tank’s exterior
surface. Place the other o-ring into the
groove on the Teflon nut, and thread the
nut onto the flange (see Figure 1). Tighten
enough to eliminate gaps between the flange
and the tank surface. This will ensure that
the o-rings are fully compressed.
