HollySys SBWR/SBWZ integrated temperature transmitter is a combination of a thermocouple (TC) or resistance temperature detector (RTD) with an integrated temperature transmitter module. This system comprises both the temperature sensing element and the associated transmitter. The temperature transmitter is housed within the junction box (case) of the temperature sensor, enabling it to directly convert the resistance or voltage signal detected by the sensor into a corresponding 4-20mA or 4-20mA + HART analog signal that represents the measured temperature. This device serves as an integrated field installation transmission unit for temperature measurement instruments and finds extensive application across various industries, including petroleum, chemical processing, metallurgy, electric power generation, food production, pharmaceuticals, and other scientific research fields. The integrated temperature transmitters are available in two types: standard type and explosion-proof type. In environments where there are no explosion-proof requirements, users should opt for the standard type; however, when flammable or explosive substances may be present during installation or operation, it is imperative to select an explosion-proof integrated temperature transmitter. Furthermore, it is essential that the ambient installation environment remains within a specified range of -25°C to 85°C. Users should also choose appropriate measurement ranges and accuracy levels based on their specific measurement needs.
Product Features
2-Wire Output Design
Utilizes two wires for both power supply and signal transmission, reducing the need for additional transmission lines and costly compensation wires.
Easy Installation and Maintenance
Fewer wiring requirements lead to simpler installation and maintenance, significantly lowering the overall cost of the temperature measurement system.
Stable and Reliable Signal Output
Directly outputs a 4-20mA DC signal with strong anti-interference capability and excellent long-distance transmission performance.
Cold Junction Compensation and Nonlinear Correction
Equipped with cold end compensation and nonlinear correction functions, ensuring the output signal maintains a linear relationship with the measured temperature.
Compatible with Display and Control Systems
The measured temperature can be directly displayed on-site via a display meter or input into a computer control system; it can also be used in conjunction with secondary instruments.
Flexible Installation Options
The temperature transmitter and sensor can be installed either integrally or separately, offering flexibility for different user needs.
Durable Encapsulation
The transmitter module is encapsulated with epoxy resin or silicone gel, providing wide ambient temperature adaptability, corrosion resistance, vibration resistance, and low static power consumption.
High Reliability and Long Service Life
Designed for safety and durability, ensuring reliable performance under harsh conditions and extended operational lifespan.
