Electrical & Acoustic PerformanceAdopts shear wave piezoelectric chip with fixed resonant frequency, perfectly matched with the excitation and receiving circuit of 868 series host equipment. Built-in integrated temperature sensing element automatically compensates sound velocity deviation caused by medium temperature fluctuation and improves overall metering accuracy. Strict impedance matching design suppresses signal attenuation during long-distance cable transmission. Each M9LW transducer passes acoustic response test and amplitude calibration before delivery, featuring stable signal transmission and low repeat measurement error for long-term continuous online operation.

Structural Design & Environmental AdaptabilityLW stands for weatherproof structure, the integral shell reaches IP67 protection rating with good waterproof, dustproof and anti-condensation performance. The coupling contact surface is equipped with wear-resistant anti-aging gasket, applicable to carbon steel, stainless steel, plastic and other common pipeline materials. Equipped with matched stainless steel quick clamping bracket for fast field installation. Applicable ambient temperature range: -40℃ ~ +70℃, adapts to outdoor pipe galleries, open-air water pump stations, coastal humid chemical areas and other harsh sites. The whole machine complies with industrial EMC standards to resist electromagnetic interference from on-site frequency converters and high-power equipment.

Matched Components & Application ScenariosMatching flow host: XMT868 / XMT868I explosion-proof ultrasonic flowmeter, AT868 wall-mounted ultrasonic transmitterMatching supporting parts: P1392 shielded coaxial cable, fixed clamp assembly, ultrasonic coupling greaseCore application scenarios: municipal water supply & drainage flow metering, thermal power outdoor circulating water monitoring, open-air petrochemical pipeline liquid measurement, industrial outdoor cooling water balance statistics. Used as standard replacement spare part when the original transducer has signal attenuation, shell aging and coupling failure.

Stability & Maintenance AdvantagesNon-contact clamp installation brings no pipeline pressure loss and no medium pollution risk, without internal mechanical moving parts to lower long-term maintenance cost. Weatherproof sealed structure reduces the failure probability caused by outdoor rainwater and humid air erosion. Standard clamping installation mode simplifies field replacement work and shortens equipment debugging downtime. Original genuine M9LW effectively avoids measurement drift caused by mismatched ordinary sensors. Shockproof sealed packaging meets long-term spare parts storage requirements, and acoustic performance remains stable under dry constant-temperature storage conditions.
