JC691 Micro Pressure Sensor / Transmitter for Wind Tunnel Overview:

For purpose of measured flow field, position of installation and placement or dynamic frequency response, when pressure measurement at the original location is required, rigorous requirements are usually laid on microminiaturization of the sensor's dimensions and re-occurrence of change laws for pulse flow field without disturbing the flow field state. JC691 micro pressure sensor / transmitter for wind tunnel is designed precisely for the above-mentioned requirements. This series of product adopts international silicon - based silicon technology of pressure sensor and high-accuracy integrated piezoresistive force-sensing elements to conduct exquisite micro encapsulation by using internationally state-of-the- art microminiaturized production and encapsulation technology so that the product is solid and durable and featured by small size, compact structure, light weight, and good dynamic and static characteristics.
