QDW90A-4-WY Aviation Connector Temperature Pressure Transmitter

QDW90A-4-WY(1)

Aviation Connector for Faster Equipment Maintenance

QDW90A-4-WY is a temperature & pressure transmitter designed around “Aviation Connector for Faster Equipment Maintenance.” The dedicated mechanical and connector structure simplifies installation, replacement and field maintenance. The dedicated mechanical, connector or mounting structure helps the instrument fit the intended pipe, tank, cabinet or equipment interface. The feature is directly relevant to hydraulic system, process pipeline and process monitoring projects. Shorten installation time and simplify later field maintenance, helping engineers keep the installation, inspection and signal path easier to manage during long-term operation.

QDW90A-4-WY(2)

Designed for OEM Equipment Integration

QDW90A-4-WY is a temperature & pressure transmitter designed around “Designed for OEM Equipment Integration.” The dedicated mechanical and connector structure simplifies installation, replacement and field maintenance. The dedicated mechanical, connector or mounting structure helps the instrument fit the intended pipe, tank, cabinet or equipment interface. The feature is directly relevant to hydraulic system, process pipeline and process monitoring projects. Shorten installation time and simplify later field maintenance, helping engineers keep the installation, inspection and signal path easier to manage during long-term operation.

QDW90A-4-WY(3)

Temperature & Pressure Feedback for Equipment Status

QDW90A-4-WY is a temperature & pressure transmitter designed around “Temperature & Pressure Feedback for Equipment Status.” Converts the measured temperature into a standard signal for PLC, DCS or display instruments. The standardized signal path routes the measured value to PLCs, DCS platforms, displays or remote monitoring equipment. The feature is directly relevant to hydraulic system, process pipeline and process monitoring projects. Connect field measurements directly to existing plc and monitoring systems, helping engineers keep the installation, inspection and signal path easier to manage during long-term operation.
