Products Description
Product Definition
The Nexisense YF-P1102 series pressure transmitter is a high-performance device specifically designed for the refrigeration and air conditioning industry. Its core function is to accurately measure the pressure of gases and liquids, widely used in refrigeration systems, compressors, and other related equipment. This transmitter utilizes an advanced ultra-thin flat ceramic pressure sensor chip and a self-designed ASIC conditioning circuit to ensure its nonlinear performance across the entire temperature range.
Working Principle
The YF-P1102 series pressure transmitter senses pressure changes and converts them into electrical signals. Its core component is the pressure sensor chip, which can detect the pressure applied to its surface. The sensor converts the pressure signal into an electrical signal, which is then amplified and linearized by the internal conditioning circuit, ultimately outputting a standardized signal (such as 4-20mA or 0-10V) for subsequent devices to read and process.
