Abstract

The invention discloses a pressure transmitter under a special environment of-40-200 DEG C. The pressure transmitter comprises a transmitter shell and a circuit board arranged in the transmitter shell, a temperature measuring element is arranged on the circuit board; the ox horn socket of the circuit board is connected with a liquid crystal display device; the circuit board is also provided with asingle-chip microcomputer chip. The transmitter shell is in threaded connection with a sensor connecting device; a pressure sensor is arranged in the sensor connecting device; a pressure change signal is transmitted to the pressure core body through the sensor connecting device; the pressure core body converts the signals into voltage signals and current signals through internal digital bridge signals, the signals are transmitted to the circuit board through the sensor connecting circuit, and the signals are processed, amplified and calculated to obtain digital signals to be displayed on theliquid crystal display device. The pressure transmitter has the characteristics of good metering stability, reliability and accuracy.

Description

technical field [0001] The invention belongs to the technical field of transmitters, and in particular relates to a pressure transmitter in a special environment of -40 to 200°C. Background technique [0002] At present, due to the development of pressure transmitters, ordinary pressure transmitters can no longer meet the use of existing special scenarios, and the ambient temperature varies greatly. The ambient temperature of special measurement is between -40 and 200°C. , the temperature variable leads to an increase in the pressure error, which is the so-called "temperature drift". At the same time, due to the material and production process of the meter display device, the display device cannot display normally, and there are phenomena such as blurred screen, black screen, garbled code, and delay. , It is impossible to view the metering data intuitively when it is applied in a special environment. Contents of the invention [0003] In order to overcome the deficiencies...
