    Product Detail

    Product Introduction

    The JT1433 Wind Speed Sensor is a representative model within JANTYTECH Technology's JT1430 series of thermal wind speed sensors for engineering applications. It is a cost-effective duct-mounted wind speed measurement sensor. The JT1430 offers unique advantages, inheriting the technological DNA of the JT1430 series sensors. It retains dual compensation to eliminate significant errors caused by air temperature fluctuations, achieving highly stable and accurate wind speed measurements.

    The JT1433 sensor features wide-range directional testing, fast response time, high sensitivity, and high precision, capable of measuring up to 20m/s. It is suitable for applications such as ventilation ducts and biosafety cabinets. The JT1433 sensor employs a rod-shaped integrated structure with a compact diameter of just 12mm and customizable length. It features a standard RS485 communication interface and outputs including 0-10V, facilitating user selection and application.

    Features

    Wide-Angle Directional Testing

    The circular wind sensor head and obstruction-free structural design enable the JT1433 to deliver exceptional consistency within a 90° range. This achieves testing across a broad angular field, eliminating errors caused by installation angle discrepancies or significant wind direction fluctuations. It is particularly suited for testing in light wind environments characterized by high randomness and volatility.

    High Integration

    The JT1433 features an integrated design combining data acquisition/transmission circuitry with the anemometer probe. Its 6-core bare wire connector eliminates the need for external transmitters, resulting in a compact, user-friendly structure.

    High Accuracy

    For thermal anemometer principles, ambient temperature (wind temperature) variation is a primary factor affecting measurement precision. This design ensures accuracy across a broader temperature range. The JT1400 series employs dual temperature compensation—physical compensation and real-time wind temperature compensation—to achieve stable, reliable, and precise corrections, enabling high-accuracy testing.

    High Reliability

    Designed entirely to industrial standards, it undergoes comprehensive testing including high/low temperature, vibration, salt spray, and protection rating tests.
