Pressure Sensor Transmitter for Oil Fields 4-20ma 0-5V pressure transmitter
Theory:
Pressure sensors are sensors used to measure the pressure of liquids and gases. Similar to other sensors, the pressure sensor converts pressure into an electrical signal output when it works. Pressure sensors are used extensively in many monitoring and control applications. In addition to direct pressure measurement, pressure sensors can also be used to indirectly measure other quantities, such as liquid/gas flow, velocity, water surface or altitude.
Structure:
The oil pressure sensor is mainly composed of three parts: pressure taker, transmission circuit and electrical output interface. The basic structure of the pressure taker is to sense the pressure change through the strip resistance, and at the same time through the Wheatstone bridge structure, the resistance change is amplified and converted into a pressure difference, and then sent to the transmission circuit for filtering, amplification and other processing. In the process of oil pressure detection, the temperature change is unavoidable. Usually, a temperature sensitive resistor is made separately from the four resistance bars of the Wheatstone bridge to simultaneously detect the temperature change in the area where the sensitive resistor is located, and correct the subsequent temperature drift. Provides a temperature value. At the same time, in order to prevent the impact of oil pressure overshoot, some products make an inverted funnel inlet at the front end of the pressure taker, which can obviously avoid and reduce the impact of oil pressure overshoot.
