HEBEI WLZ0822 Industrial Vibration Transmitter Product Description

OverviewHEBEI WLZ0822 is a domestically manufactured integrated vibration transmitter developed by Hebei local industrial sensor enterprise. HEBEI WLZ0822 adopts piezoelectric sensing principle, which can collect vibration velocity and vibration amplitude signals of rotating machinery such as fans, pumps and motors, and convert them into standard 4-20mA analog output. It is widely used in the condition monitoring and protection of equipment in steel, thermal power, cement and water treatment industries in North China. In recent local industrial upgrading projects, HEBEI WLZ0822 has been matched with domestic TSI monitoring racks and DCS systems to realize localized replacement of imported vibration sensors, shortening delivery cycle and reducing procurement cost. This vibration transmitter is a conventional spare part for equipment overhaul and transformation of industrial enterprises in Hebei and surrounding regions.

FeaturesHEBEI WLZ0822 adopts stainless steel sealed housing, with built-in signal conditioning circuit and temperature compensation function. The vibration transmitter has good anti-interference performance and stable output in high-temperature and dusty workshop environment. It supports direct installation on bearing housing, simple wiring and no extra signal converter. The product has passed domestic explosion-proof and metrology certification, and can be used in general non-explosive and intrinsically safe occasions. HEBEI WLZ0822 can be directly connected with PLC, paperless recorder and monitoring host, and provides stable after-sales and technical support from local manufacturers.

PrincipleHEBEI WLZ0822 picks up mechanical vibration through the built-in piezoelectric chip, converts vibration energy into weak charge signal, and then completes amplification, filtering and temperature compensation inside the transmitter. The vibration transmitter converts the processed vibration signal into standard 4-2mA current signal linearly corresponding to vibration value and transmits it to the upper monitoring system. The background circuit continuously self-checks the sensor state. Once signal loss or abnormal circuit is detected, HEBEI WLZ0822 outputs fault current for host alarm.

ApplicationsHEBEI WLZ0822 is widely deployed in steel mills, thermal power plants, cement plants, water pump stations and waste heat power stations in Hebei and North China. The vibration transmitter is used for bearing vibration monitoring of fans, centrifugal pumps, induced draft fans and small motors. It cooperates with domestic monitoring modules, alarm instruments and DCS to realize equipment condition early warning. HEBEI WLZ0822 is the mainstream localized alternative spare for imported vibration sensors.
