Electrical & Acoustic PerformanceBuilt-in high-temperature resistant piezoelectric chip with matched resonant frequency, matched with the transmitting and receiving circuit of 868 series host. The built-in long waveguide structure isolates high-temperature heat conduction to protect the piezoelectric element from overheating failure. Integral built-in temperature sensing element compensates sound velocity deviation caused by medium temperature change, optimizes measurement accuracy under wide temperature fluctuation. Strict impedance matching reduces signal attenuation during long-distance cable transmission. Each transducer undergoes acoustic response testing and amplitude calibration before factory delivery, with stable signal transmission and low measurement repeat error during long-term continuous operation.

Structural Design & Environmental AdaptabilityThe wetted part is made of high-temperature resistant stainless steel material, the whole structure can adapt to medium temperature up to 260℃. Standard threaded insertion structure matches pipeline welded base, convenient for online installation and replacement without long-term shutdown. The outer shell reaches IP65 protection grade, internal components are treated with high temperature insulation coating, resistant to high temperature radiation, dust, damp and weak corrosive medium erosion. It has strong mechanical vibration resistance, adapts to pipeline vibration of boiler, heating furnace and refining device, and complies with industrial EMC anti-interference specifications.

Matched Components & Application ScenariosMatching host equipment: XMT868 / XMT868I explosion-proof liquid flow transmitter, GS868 steam ultrasonic flowmeterMatching accessories: P1392 signal coaxial cable, welded mounting base, high temperature coupling fillerMain application scenarios: boiler high-temperature hot water flow measurement, petrochemical high-temperature process liquid metering, saturated/superheated steam pipeline flow monitoring, thermal power heat medium pipeline flow balance statistics. Used as replacement spare part when the original probe has signal attenuation, high-temperature aging and measurement instability faults.

Stability & Maintenance AdvantagesWaveguide heat isolation design greatly prolongs the service life of the core piezoelectric chip, no internal moving mechanical parts, low long-term maintenance workload and operation cost. Standard threaded insertion installation simplifies field disassembly and replacement operation, effectively shortening equipment debugging downtime. Original genuine 1200HR avoids measurement drift and mainboard circuit damage caused by mismatched ordinary high-temperature probes. Shockproof sealed packaging meets long-term spare parts storage requirements, and acoustic performance remains stable under dry constant-temperature storage environment.
