U-GAGE Chemically Resistant Ultrasonic
Sensors
• Chemical-resistant option available for all Banner QT50U, T30U
and T30UX..C models
• Factory-installed PTFE 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-ring1;
other o-ring materials may be specified (contact Banner
Engineering)
• Performance specifications for these models are identical to those
of corresponding standard models, with the exception of reduced
sensing range
• Sensor dimensions and mounting vary somewhat from
corresponding standard models (see dimensions)
Models
Add suffix "-CRFV" to the model number of any standard QT50U, T30U or T30UX..C model sensor for the chemically
resistant flange and coating. For example: QT50ULBQ6-CRFV or T30UINB-CRFV.
1) T30U..A - 150 mm to 500 mm (5.9 inches to 19.6 inches)
2) T30U..B - 300 mm to 1 m (11.8 inches to 39 inches)
3) T30UX..C - 300 mm to 1.5 m (11.8 inches to 59 inches)
4) QT50U - 200 mm to 6 m ( 7.8 inches to 19.6 feet)
Installing the Chemical-Resistant Models
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. Recommended
through-hole size: 56.5 mm ± 0.5 mm for
QT50U and 36.5 mm ± 0.5 mm for T30U.
For a non-threaded hole, install an o-ring
onto the flange, and insert the flange
completely into the hole until the sensor's
front surface is against the tank’s exterior
surface. Place the second o-ring into the
groove on the PTFE nut. Thread the nut
onto the flange and tighten enough to
eliminate gaps between the flange and the
tank surface. This ensures that the o-rings
are fully compressed.
