Overview
The AVKP90 digital output pressure transmitter is a new generation of intelligent digital products, characterized by high precision, high reliability, convenient use and installation. The product has a wide voltage range, low power consumption, and multi-level protection design, with strong anti-interference ability. The standard IIC bus has a maximum speed of 400K, a collection rate of 50 times/second, a power consumption of less than 2mA during operation, and a standby current of 1uA. The standard IIC communication protocol makes this transmitter particularly suitable for computer control systems.
The pressure seat of AVKP90 digital output pressure transmitter is processed with a single piece integrated structure of 316L stainless steel or 17-4PH stainless steel, with high overload performance. Its pressure interface has no welds, silicone oil or other organic substances, and good sealing performance. The sensitive components of the sensor are firmly sintered on the pressure seat using glass micro melting technology, greatly improving the high temperature and vibration resistance of the sensor, ensuring the long-term stability, reliability, and durability of the transmitter in harsh industrial environments. In the standard purification production process, all parameters are strictly controlled, and the entire product has undergone strict testing and aging screening of components, semi-finished products, and finished products, with stable and reliable performance.
