CS-V type differential pressure transmitter

The working principle of CS-V differential pressure transmitter is based on the principle of piezoresistive sensor. Its structure includes probes, pressure tubes, and measuring elements. The probe is installed on the measuring medium pipeline. When the measuring medium passes through the probe, the pressure of the medium will act on the diaphragm on the probe. The diaphragm is covered with a specially designed varistor, which undergoes slight deformation under pressure, thereby changing the resistance value of the varistor. This change in resistance value is transmitted to the measuring element through a pressure tube, and the circuit in the measuring element samples the resistance value of the piezoresistive sensor and amplifies it through an amplifier. The amplified signal is converted into a digital signal through an A/D converter, and then connected to a display or control system for display or control.

In addition, the CS-V differential pressure transmitter can also consist of two measurement chambers equipped with pressure sensors, located upstream and downstream of the pipeline. When a fluid passes through a pipeline, the pressure difference between the fluid will cause changes in the pressure signals of the upstream and downstream measurement chambers. These pressure signals will be collected by sensors and converted into electrical signals, which will then be processed by a signal processor to ultimately output the numerical value of the pressure difference.
