WS9050 RTD Temperature Transmitter

WS9050 temperature transmitter for Pt100 Pt1000 and Cu50 RTD signal conversion

Reliable RTD Measurement & Conversion

WS9050 is a temperature transmitter designed around “Reliable Rtd Measurement & Conversion.” Supports PT100, Cu50 for stable RTD measurement and system integration. The sensing structure converts the physical process variable into a clear signal for industrial monitoring and automation. The confirmed values highlighted here are PT100, Cu50. The feature is directly relevant to water tank, control cabinet and process pipeline projects. Improve measurement clarity and maintenance efficiency in water tank applications, helping engineers keep the installation, inspection and signal path easier to manage during long-term operation.

DIN rail RTD temperature transmitter for centralized industrial temperature monitoring

Direct Single-channel Temperature Conversion

WS9050 is a temperature transmitter designed around “Direct Single-channel Temperature Conversion.” Multiple channel arrangements support centralized temperature monitoring. The channel and model arrangement makes it easier to match the number of field points without changing the overall cabinet architecture. The feature is directly relevant to water tank, control cabinet and process pipeline projects. Handle more monitoring points with fewer separate cabinet modules, helping engineers keep the installation, inspection and signal path easier to manage during long-term operation.

RTD temperature transmitter with standard analog output for PLC and DCS systems

Standard Temperature Output for Control Systems

WS9050 is a temperature transmitter designed around “Standard Temperature Output for Control Systems.” Supports 4–20mA, 0–5V, 0–10V, RS485, PT100 for stable temperature measurement and system integration. The standardized signal path routes the measured value to PLCs, DCS platforms, displays or remote monitoring equipment. The confirmed values highlighted here are 4–20mA, 0–5V, 0–10V, RS485. The feature is directly relevant to water tank, control cabinet and process pipeline 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.
