Description
Chuanyi WR Series Thermocouple Technical Data and Selection Guide
Chuanyi WR Series Thermocouple is supplied by SANTAN for industrial process control, pipeline instrumentation and maintenance replacement projects.
Product Overview
Chuanyi WR series thermocouples measure industrial process temperature using the Seebeck effect. The product family includes assembled and mineral-insulated constructions combined with application-specific thermowells, mounting components and terminal heads.
Chuanyi Product-Family Information
The WR family is used across petroleum, petrochemical, coal chemical, fine chemical, power, metallurgy and building-material processes. Sensor construction and protection assemblies are selected for temperature, pressure, corrosion, vibration, abrasion and response-time requirements.
Detailed Technical Parameters
| Parameter | Selection Guidance |
|---|---|
| Measurement principle | Thermoelectric voltage generated by two dissimilar conductors |
| Sensor types | Thermocouple type selected for temperature range, atmosphere and accuracy requirement |
| Construction | Assembled or mineral-insulated (MI) element |
| Junction | Grounded, ungrounded or exposed junction according to response and isolation needs |
| Protection | Thermowell or protection tube selected for pressure, velocity, corrosion and abrasion |
| Process mounting | Threaded, flanged, welded socket or project-specific assembly |
| Electrical connection | Terminal head or transmitter assembly; extension/compensation cable must match thermocouple type |
| Response time | Depends on element diameter, junction construction, sheath and thermowell design |
| Accuracy | Tolerance class and calibration requirement to be specified |
| Options | Duplex element, head-mounted transmitter, local display and hazardous-area configuration |
Typical Industry Applications
Reactors, furnaces, boilers, steam lines, heat exchangers, kilns, process vessels, rotating equipment and high-temperature piping.
Information Required for Model Selection
Thermocouple type, measuring and design temperature, process pressure, medium, sheath and thermowell material, insertion length, process connection, junction type, element diameter, head type, transmitter/output, hazardous-area certification and calibration.
Engineering Notes
- Confirm the complete model code and nameplate data before ordering a replacement.
- Verify process compatibility, pressure/temperature limits and installation conditions against the approved manufacturer datasheet.
- Final specifications vary by model suffix, material, connection, signal and certification option.
- SANTAN can review datasheets, project tags and replacement requirements before quotation.
