Ultrasonic sensors resist chemicals

Chemical protection for ultrasonic sensors comes from a factory-installed Teflon flange and film coating bonded over the sensors transducer, sealing against gases and vapors.

Banner Engineering announces the addition of chemically resistant models to their U-Gage line of ultrasonic sensors.

The chemical protection comes from a factory-installed Teflon flange and film coating bonded over the sensors transducer, sealing against gases and vapors that would destroy standard models.

Chemically resistant U-Gage ultrasonic sensors are available in all QT50U and most T30U models and are ideal for a wide variety of level control applications in cleaning, etching and other chemical processes where material is corrosive or caustic.

QT50U models have a sensing range of 200mm to 8m, and T30U models have a sensing range of 300mm to 1.5m.

With the exception of range, performance specifications for both sensors are identical to those of the corresponding standard models and include the following: * A variety of outputs and voltages.

* QT50U models available with 10 to 30V DC and analog or discrete outputs, and universal voltage 85 to 264V AC/24 to 250V DC with a SPDT electromechanical relay output.

* T30U models with 10 to 30V DC with discrete or analog/discrete outputs.

* Fast, easy-to-use teach programming that uses two on-board push buttons.

* Fully encapsulated designs rated IP67, NEMA 6P for use in harsh environments.

* Inherent immunity to target color differences and high-power light interference.

* Bright LEDs that display status during set-up and operation, * Models with high/low limit controls, * Unique housings for multiple mounting configurations using the sensor's threaded nose or a variety of brackets,.
