Import Circular Plate Transmitter Series — Buy in Bulk from Supplier in China

The Circular Plate Transmitter Series from Keyan Auto-Control Apparatus Co., Ltd. is a family of pressure, temperature, and flow transmitters designed for industrial process monitoring. These devices feature a measurement tolerance of ±0.5% of full scale and are constructed with stainless steel housings rated for IP65 ingress protection. The transmitters use piezoresistive or capacitive sensing elements, depending on the model, to convert physical parameters into standardized electrical signals.

Typical output signals include 4 - 20 mA and 0 - 10 V DC, compatible with most PLC and SCADA systems. The operating temperature range is -20°C to +85°C, and the pressure range varies by model from 0 - 1 bar up to 0 - 400 bar. These transmitters are built for use in environments with vibration, humidity, and dust, making them suitable for oil and gas pipelines, water treatment plants, and automated manufacturing lines.

End users include process engineers in chemical plants, municipal water utilities, and food processing facilities. Units are shipped in sealed plastic cases with foam inserts, typically 10 per carton. Bulk orders are packed in corrugated cartons inside palletized wooden crates. Trade terms are usually FOB Guangzhou or CIF destination. Confirm calibration certificate, material certification, and signal output type before ordering.
