Product Introduction
The SBWZ Series Integrated Temperature Transmitter combines a Pt100 RTD temperature sensor and a temperature transmitter module into one compact industrial temperature measuring device.
The built-in transmitter converts the Pt100 resistance signal into a standard two-wire 4-20mA output signal, which can be directly connected to PLC, DCS and industrial control systems.
The sensor adopts a 3-wire Pt100 measuring element, Φ6mm mineral insulated RTD probe, and SS316L protection tube, providing excellent corrosion resistance, vibration resistance and long service life.
The aluminum alloy waterproof terminal box protects the internal transmitter module and wiring connection, making it suitable for industrial field installation.
An independent SS304 thermowell is included to provide additional protection and easy maintenance.
Applications
Chemical processing equipment
Petrochemical pipelines
Oil and gas industry
Boiler and heating systems
Water treatment equipment
Food processing machinery
Pharmaceutical equipment
HVAC systems
Industrial automation systems
Storage tanks and reactors
