The AOF1000 series intelligent temperature transmitter is a small, high-performance and high-precision temperature measurement instrument. It has the characteristics of small size, light weight, and easy installation. It can convert the temperature parameters of the control object into electrical signals and transmit them to display, recording, and regulating instruments for system detection, adjustment, and control. The transmitter features intelligent non-linear compensation, universal input for all types of temperature sensors, linearized 4-20mA current output, automatic cold junction compensation, and user-configurable settings. It is widely used in major projects in the oilfield, petrochemical, manufacturing, power, and metallurgical industries.
The AOF1000 series intelligent temperature transmitter is a compact, high‑precision measuring instrument that converts temperature parameters into a 4‑20 mA signal for display, recording or control. It can be installed directly in the wiring box of standard thermocouples or resistance temperature detectors, reducing wiring length and signal distortion.
The device offers software‑adjustable range, linearization, polarity‑reverse protection, and cold‑junction compensation. It supports a wide variety of input types and can be integrated with DCS, PLC, or unit‑combined meters for use in oil‑field, petrochemical, manufacturing, power, and metallurgy projects.
