Terry Ferraris’ UTF ultrasonic transducers are designed to meet the precision and reliability requirements needed for all solid and liquid level measurement and control processes. The decision to use a low voltage in the connections to the control electronic equipment and the non-frequency dependency allows for high performance and low installation costs as the connection is made via a three-core shielded cable. Since the connection to the electronics is not frequency-dependent, transducers can be replaced without having to recalibrate the electronics, and the transducer can be placed up to 3000m away from the electronics without compromising measurement reliability. The use of low voltage also enables intrinsic safety certification for use in flammable atmospheres. The UTF transducer is based on a ceramic PTZ element, compensated in temperature and is suitable for level measurement of solids and liquids with measuring ranges between 0.2 and 50m, and operates in environments with temperatures between – 30/-40 and 90°C.
The standard cable length is 5m. UTF transducers can be installed using the 1″, 1 ½ ” or 2″ Gas threaded connection or using a flange.
With the flange, the use of a gasket is recommended in order to prevent any vibrations in the system from causing interference. For applications where threaded or flanged connections cannot be used, it is recommended to use a safety chain to prevent the transducer cable from being damaged.
For applications in silos or tanks for solid materials, an orientation joint is available, which is used to orient the ultrasonic beam at the bottom of the tank or at the discharge point so that there is no interference with the loaded materials.
For liquid applications, a protective shield is available on request, enabling the transducer to function even if it is submerged.
For use on solids, the transducers have a protective soft foam membrane and use an orientation joint.
