SBWZ
Jiechuang
The Pt100 Integrated Temperature Transmitter with Mineral-Insulated Probe is designed for industrial process temperature measurement. It combines a Pt100 resistance temperature detector (RTD) with a built-in temperature transmitter in one compact assembly.
The transmitter converts the Pt100 resistance signal into a standard 4–20 mA output for compatible PLC, DCS, and industrial control systems. The mineral-insulated probe provides a compact sensing structure for industrial installation. A separate thermowell can provide additional mechanical protection when the assembly is designed for use with the specified process connection.
The SBWZ series is intended for temperature monitoring in industrial pipelines, tanks, process equipment, and other compatible installations. Measuring range, probe dimensions, connection details, output configuration, communication functions, and enclosure protection should be confirmed for the selected model before ordering.
Used for process temperature monitoring where the sensor materials and assembly design are compatible with the process medium and operating conditions.
Provides a temperature measurement point for compatible pipeline installations. Confirm the connection, pressure conditions, and thermowell design before use.
Can be considered for temperature monitoring in compatible heating equipment. Verify the required temperature range and assembly limitations.
Supports process temperature measurement in compatible water treatment systems. Select wetted materials according to water chemistry and treatment additives.
Provides a 4–20 mA temperature signal to compatible monitoring and control equipment.
Can be used for temperature measurement where the installation connection, insertion length, and sensor construction suit the vessel design.
Application suitability must be evaluated against the actual process conditions and confirmed product ratings.
Integrated Pt100 and Transmitter: Combines temperature sensing and signal conversion in one assembly, simplifying the interface with compatible control systems.
