Digital signal pressure sensor 485 pressure transmitter

Description :

　　Digital signal pressure sensor 485 pressure transmitter HR3100

　　Overview

　　HR3100 digital signal pressure sensor 485 pressure transmitter is a high-precision digital pressure measurement product independently developed by our company and accumulated through years of production process technology. It adopts advanced mixed signal processing technology and unique compensation methods to achieve full range digital linear correction, full temperature range digital temperature error compensation, compensation parameters stored in non-volatile memory, and multiple safety protection mechanisms to avoid product failure due to calibration parameter loss; The circuit part is equipped with power monitoring and watchdog monitoring functions, and the mechanical part is a fully sealed stainless steel structure, greatly improving the reliability of the entire machine. Due to the use of low-power devices in all circuits, the overall power consumption of the machine is very low, with approximately 4mA at full speed operation. This feature is very useful in situations where battery power is required. High precision digital pressure transmitter products have been successfully mass-produced in many industries, such as pressure measurement in industrial processes, hydrology and water conservancy, geological exploration, and other fields.
