Working Principle and Electrical Performance

This transducer uses piezoelectric crystal elements to realize mutual conversion between electrical excitation signals and ultrasonic acoustic waves. Ultrasonic signals penetrate the pipe wall and liquid medium, and the reflected echo signals are transmitted back to the host for time-difference operation to calculate flow velocity and flow rate. The built-in impedance matching circuit effectively reduces acoustic signal attenuation during propagation and suppresses signal distortion caused by pipeline scale, fluid impurities and field electromagnetic interference. Each unit undergoes unified acoustic parameter calibration before delivery, featuring stable echo response and high signal-to-noise ratio within the applicable pipe diameter range. Internal electronic components pass high-low temperature aging screening to maintain stable acoustic output performance under long-term continuous operating conditions. Standard signal transmission cables ensure low-loss data transmission between the probe and the flow transmitter.

Structural Design and Environmental Adaptability

The transducer shell is made of high-strength wear-resistant engineering plastic with excellent weather resistance and corrosion resistance, adapting to outdoor pipe galleries, chemical workshops, thermal power plants and water treatment workshops. The sound-conducting contact surface is equipped with a wear-resistant coupling pad to closely fit the outer wall of metal and plastic pipelines and reduce acoustic transmission loss. The cable outlet adopts an integrated sealed waterproof structure to prevent moisture, dust and condensate from invading internal piezoelectric chips. The overall structure meets industrial EMC anti-interference standards and can resist interference from surrounding motors, inverters and power distribution equipment. The lightweight clamping structure is easy to fix on the pipeline surface without cutting the pipeline or stopping production during installation and maintenance.

Matching Equipment and Application Scenarios

Perfectly compatible with GE XMT868 fixed ultrasonic transmitters, AT868 portable flow meters and UTX878 series measurement hosts. Widely used in municipal water supply and drainage pipeline flow monitoring, power plant circulating water system measurement, petrochemical liquid pipeline flow detection, metallurgical cooling water monitoring and industrial energy balance testing. It is a core replacement spare part when the original transducer has weak echo signals, signal loss and shell aging damage, which can quickly restore the normal measurement function of the flow metering system and reduce the economic loss caused by instrument shutdown.

Stability and Maintenance Advantages

Every UTXDR407 transducer passes acoustic performance test, air tightness inspection and long-term signal stability aging test before leaving the factory to ensure consistent performance of different batches. The standard wiring interface supports plug-and-play connection without complex debugging after replacement. Field maintenance personnel can complete installation and fixation quickly with matching clamps and coupling agents to save enterprise maintenance labor costs. Original GE transducers can avoid measurement deviation and host circuit overload faults caused by inferior generic sensors. Shockproof sealed packaging is suitable for long-term storage in industrial spare parts warehouses, and acoustic sensing performance will not degrade significantly under dry and constant temperature storage environment.
