QDW90A-WY Compact Temperature and Pressure Transmitter

QDW90A-WY temperature pressure transmitter with Hirschmann connector for reliable field wiring and maintenance

Hirschmann Connector for Reliable Field Wiring

QDW90A-WY is a temperature & pressure transmitter designed around “Hirschmann Connector for Reliable Field Wiring.” 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 compressed air system, hydraulic system and cooling system 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.

Unified Temperature & Pressure Signals for Control Systems

QDW90A-WY is a temperature & pressure transmitter designed around “Unified Temperature & Pressure Signals for Control Systems.” Converts the measured industrial signal 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 compressed air system, hydraulic system and cooling system 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.
