Product introduction
JT1411 omnidirectional wind speed sensor is a spherical packaged miniature wind speed sensor with high three-dimensional uniformity and flexible layout. The miniature special packaging structure with the maximum size less than 7mm is suitable for testing in small spaces such as circuits and electrical equipment. The transmission circuit has standard RS485, 4~20mA, 0~10V and other output waterproof, which is convenient for integrated use.
JT1411 wind speed sensor is a miniature wind speed sensor with small size and high sensitivity. It can be integrated into the circuit. It is suitable for the wind speed test and control of the heat dissipation environment in the chassis of electrical appliances and circuits, so as to ensure the safe operation and good heat dissipation performance of electrical equipment.
The maximum size is only 7mm, which can be flexibly arranged on the circuit board or on the cabinet. The digital signal and analog signal output can be switched freely.
The temperature-sensing probe made of special material is not easy to be damaged.
The spherically packaged probe ensures the uniformity of the three-dimensional direction.
The characteristics of extremely small size and multi-signal output make JT1411 have more applications. It is necessary to arrange multiple measurement points in the HVAC dummy model. Traditional wind speed sensors are difficult to arrange due to their large size and easy damage. JT1411 takes advantage of its small and durable features It can be arranged at multiple points on the surface of the dummy model, and because the height is only 7mm, they will not affect the measurement of each other. We also support complete customization services, and can provide wind speed and temperature integrated circuit design and manufacture.
Micro-probes that can be used for onboard or cabinet installation.
The server in the data center undertakes an important mission. The high-load operation makes the temperature inside the cabinet rise sharply. Ensuring good heat dissipation becomes an important consideration. The JT1411 wind speed sensor can be directly integrated into the circuit for use It is used to control the start or speed of the fan in the chassis, precisely control the temperature, and ensure the optimal performance and service life of the equipment.
Directional response
JT1411 wind speed sensor probe is omnidirectional response, this performance is especially important for wind speed measurement of unknown wind direction or unstable wind direction, random wind direction, JT1411 has excellent directional response characteristics in the horizontal direction, at different angles (the wind direction is perpendicular to the probe Direction) can maintain fast response and accurate measurement of the incoming wind direction.
Specification Size
The design of the split wind speed and temperature measurement probe is easy to arrange in the internal wind speed monitoring of electronic equipment for ventilation and heat dissipation.
