Electrical & Acoustic Performance

Built-in piezoelectric chip with fixed resonant frequency matching the host transmitting and receiving circuit. The built-in long waveguide structure isolates heat conduction to prevent high temperature from damaging the piezoelectric core component. Integrated temperature sensing element automatically compensates sound velocity changes caused by medium temperature fluctuation and optimizes overall measurement precision. Strict impedance matching suppresses signal attenuation during long-distance cable transmission. Each USL-42 undergoes acoustic response calibration and signal amplitude detection before factory delivery to maintain stable signal output and low repeat error during long-term continuous measurement.

Structural Design & Environmental Adaptability

The wetted contact part is made of high-strength stainless steel material, supporting medium temperature up to 230℃. Adopts standard threaded insertion structure with matched welded base, allowing online plug-in replacement without long-time system shutdown. The overall protection grade reaches IP65, the internal components are coated with high-temperature insulation coating to resist dust, moisture and weak corrosive gas erosion. Excellent anti-vibration performance adapts to pipeline vibration generated by boilers, heat exchange equipment and pump sets, fully complying with industrial EMC anti-interference standards.

Matched Components & Application Scenarios

Matching host equipment: GS868 steam ultrasonic mass flowmeter, XMT868 / XMT868I industrial liquid flow transmitter

Matching accessories: P1392 shielded coaxial cable, pipeline welding base, high-temperature coupling filler

Core application scenarios: saturated & superheated steam pipeline metering, thermal power heat medium pipeline flow balance, petrochemical high-temperature process liquid monitoring, heating system steam flow statistics. Used as replacement spare part when original probe has signal attenuation, high-temperature aging and unstable measuring data.

Stability & Maintenance Advantages

Waveguide thermal isolation design effectively extends the service life of piezoelectric elements; no internal mechanical moving parts reduces long-term maintenance workload and operating cost. Standard threaded insertion installation simplifies field disassembly work and shortens equipment debugging downtime. Original genuine USL-42 avoids measuring drift and mainboard circuit abnormities caused by mismatched generic sensors. Shockproof sealed packaging meets long-term spare parts storage demands, and acoustic performance remains stable under dry constant-temperature storage environments.
