WSS-401 Adjustable Bimetal Thermometer
WSS-401 is a bimetal thermometer designed around “Clear Local Display for Faster Field Inspection.” Displays the measured value directly at the process point for easier inspection and commissioning. The local display makes the live value and operating state easier to verify during commissioning, inspection and routine maintenance. The feature is directly relevant to process pipeline, water tank and temperature monitoring projects. Check operating status directly without opening the control system, helping engineers keep the installation, inspection and signal path easier to manage during long-term operation.
WSS-401 is a bimetal thermometer designed around “Installation-focused Design for Bimetal Thermometer.” 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 process pipeline, water tank and temperature 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.
WSS-401 is a bimetal thermometer designed around “Customizable Connection and Gauge Specifications.” 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 confirmed values highlighted here are 60, 100, 150mm, 10mm. The feature is directly relevant to process pipeline, water tank and temperature 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.
