Pressure measurement series
The Firstrate pressure measurement series mainly includes low-power pressure measurement and wireless pressure measurement products, which are specially developed for the application environment of the Internet of Things, using wired, battery-powered and periodic power supply options. This series of products includes RS485 output of Modbus RTU protocol, I2C output of integrated circuit bus and analog output between 0.25~2.5V. It is wirelessly connected to the cloud by GPRS/4G/LoRa/NB-Iot transmission to realize automatic data storage and Online analysis and monitoring. This series of products is particularly suitable for intelligent monitoring scenarios such as oil, gas, heating, fire-fighting water pipe networks, and unattended and inability to implement power supply.
The pressure sensor has a built-in high-performance digital circuit, carefully designed for radio frequency, electromagnetic interference, and surge voltage conditions. It has the characteristics of strong anti-interference ability and polarity protection, and meets IEC and CE (EMC) standards. The intelligent digital temperature compensation circuit and the calibration value corresponding to the temperature change are stored in the chip. When the sensor is affected by temperature, it can automatically compensate, which solves the temperature drift of the sensor and improves the measurement accuracy of the sensor and the adaptability of the environment.
