Import Bfp Rotation Speed Probe Cs-3 — Buy in wholesale FOB from Supplier in China

The BFP Rotation Speed Probe CS-3 is a passive magnetic speed sensor designed for boiler feed pump (BFP) monitoring in thermal power generation. It detects rotational speed by sensing ferromagnetic gear teeth or keyphor passing its pole piece, generating an analogue voltage signal proportional to shaft speed. The probe operates without external excitation, making it suitable for continuous duty in high-vibration turbine hall environments. Deyang Dongfang Yoyik Engineering Co., Ltd. develops this probe for integration with their wider power plant instrumentation portfolio, which includes eddy current sensors, LVDT position transmitters and thermocouple assemblies.

The CS-3 probe body is typically manufactured from stainless steel with a hardened sensing face to resist wear against rotating targets. Standard industry construction includes a threaded mounting body, sealed cable entry and mineral-insulated cable to withstand temperatures common in bearing housing applications. The passive electromagnetic principle means the sensor contains no active electronics at the probe tip, improving reliability in zones with temperature cycling. Typical output is a sinusoidal mV signal whose frequency corresponds to rotational speed, with amplitude dependent on target surface speed and air gap. Industry-standard thread specifications and connector types are typical for this probe class, though buyers should confirm exact mechanical details against their installation drawing.

Power plant operators and maintenance contractors use the CS-3 for BFP protection, overspeed detection and speed feedback to turbine control systems. The probe interfaces with vibration monitoring racks, speed trip modules and distributed control systems from major automation suppliers. Buyers should verify the probe's electrical compatibility with their existing speed monitoring chain, including signal conditioning requirements and threshold settings. Deyang Dongfang Yoyik Engineering Co., Ltd. lists this probe alongside complementary items such as the GJCD-15 passive sensor and DET-100B displacement probe, suggesting capability to supply matched instrumentation sets for overhaul projects.

Deyang Dongfang Yoyik Engineering Co., Ltd. is based in Deyang, Sichuan Province, China, with offices at Huashan Plaza in Jingyang District. The company operates as an integrated research, development and manufacturing business focused on spare parts for thermal power plants. Its product scope spans sealants, insulation materials, pump and valve components, sensors and heating elements for the chemical, electric power and steel sectors. The supplier holds a harbor trust tier on the platform, with a listed response rate of 0.00 percent and no recorded average response time. Buyers should note that these engagement metrics suggest limited active communication through this channel and should plan direct outreach for technical discussions.

The supplier's catalogue indicates capability to produce or source a wide array of power plant specialities beyond the CS-3 probe, including eddy current sensors (PR6423 and PR6424 series), LVDT position transmitters, thermocouple types K and E, RTD assemblies, bolt heaters and hydraulic actuator components. The company describes its approach as integrity management and service first, though no third-party certifications, factory audit results or specific quality management system registrations are stated in the available profile. Buyers are advised to request supplier qualification documents, ISO certificates where applicable, and reference installations before committing to large orders.
