Product introduction
JT1420 hot film directional wind speed sensor is a professional wind speed sensor developed based on the principle of film-like high-sensitivity thermistor temperature measurement. The sensor has the characteristics of long life and high stability, which can stably test the wind speed in the ventilation duct, and is suitable for long-term online monitoring.
The sensor adopts a rod-shaped structure and is designed separately from the transmitter circuit. The extension cable interface is reserved, which can be fixed on the pipe wall through the locking wire seat.
The transmitter box has a built-in industrial grade acquisition circuit, and has RS485, 0~10V, 4~20mA output, which is convenient for users to choose.
The sensor adopts all stainless steel structure, which has stronger environmental adaptability, stability and reliability.
JT1420 wind speed sensor is a hot-film wind speed sensor with the characteristics of good stability, long life and strong adaptability. The sensor is directional wind speed and has good wind speed consistency within ±20°. Suitable for pipeline wind speed monitoring.
Wind speed, wind temperature dual output.
Solid aluminum alloy shell, stainless steel probe.
Integral type, split type optional.
With LCD screen.
RS485, 4~20mA, 0~10V output signal optional.
Technical performance
High sensitivity.
Fast response, accurate measurement.
Fast response time, which is especially important in scenes with drastic changes in wind speed, can record wind speed data faster to ensure data reliability and provide more guarantees for research.
The impact of angle deviation
JT1420 maintains excellent measurement accuracy within the range of ±20° parallel to the measurement hole, which allows the user to have a certain deviation during installation without affecting the measurement accuracy.
Specification and size
Shape size
integrated
sensor and host integrated design,
can be directly installed in the pipeline measurement hole.
Split type
The sensor and the host are split, and cables of different lengths can be flexibly configured according to the site conditions.
