Electrical & Acoustic PerformanceBuilt-in matched piezoelectric chip with fixed resonant frequency, matching the signal excitation frequency of 868 series flowmeter mainboard. Bidirectional transmission and reception of ultrasonic signals, with stable acoustic coupling efficiency after surface coupling with pipe outer wall. Strict impedance matching design reduces signal attenuation during long-distance cable transmission. The integrated built-in temperature sensing element compensates sound velocity deviation caused by medium temperature changes, improving overall measurement precision. Each transducer undergoes acoustic calibration and signal amplitude testing before delivery, measurement repeatability error is controlled within a tiny range, adapting to long-term continuous online measurement.

Structural & Environmental AdaptabilityThe shell uses high-strength anti-corrosion engineering plastic with IP65 protection grade; the contact surface is equipped with wear-resistant coupling gasket, resistant to outdoor dust, damp and weak corrosive atmosphere. Standard stainless steel clamping fixture is equipped for fast locking on carbon steel, stainless steel, copper and other common metal pipelines. Wide applicable medium temperature range, normal working ambient temperature -40℃ ~ +70℃. The overall structure has good vibration resistance, can adapt to pipeline vibration of water pump and valve opening/closing in industrial sites, and conforms to industrial EMC anti-interference specifications.

Matched Parts & Application ScenariosMatching host: XMT868 / XMT868I explosion-proof flow transmitter, AT868 wall-mounted ultrasonic flowmeterMatching accessories: P1392 dedicated coaxial signal wire, fixed clamping bracket, acoustic coupling pasteMain applications: thermal power circulating water metering, petrochemical process liquid monitoring, municipal water supply and sewage flow measurement, factory cooling water balance statistics. It is a standard replacement spare part when the original probe has signal attenuation, casing aging and coupling failure.

Stability & Maintenance AdvantagesNon-invasive installation will not cause pipeline pressure loss, no contact with measured medium, zero medium pollution risk. No internal mechanical moving parts, low daily maintenance cost. Standard clamping installation mode simplifies on-site replacement construction and shortens system debugging downtime. Original genuine PWO6J8-4S effectively avoids measurement drift caused by mismatched generic probes. Shockproof sealed packaging meets long-term spare parts storage requirements, and acoustic performance keeps stable under dry constant-temperature storage conditions.
