(R) U-GAGE Chemically Resistant Ultrasonic Sensors (R) 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(R) 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). Teflon(R) is a registered trademark of DupontTM Viton(R) is a registered trademark of Dupont Dow Elastomers 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. Performance Curves QT50U Max. Sensing Range: 200 mm to 8 m (8" to 26') T30U..B Max.

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. Figure 1.
