Product Specifications

Technical details and manufacturing context for Precision Pressure Transducer Sensing Element

Definition

A precision pressure transducer sensing element is the fundamental component within pressure measurement instruments that directly interacts with fluid or gas pressure. It transforms mechanical pressure forces into proportional electrical signals through piezoresistive, capacitive, or strain gauge principles. This component serves as the critical interface in industrial process control systems, enabling accurate pressure monitoring in manufacturing, HVAC, and aerospace applications. As a B2B supply chain item, it's manufactured to exacting specifications for integration into OEM pressure transmitters and gauges. The sensing element is typically constructed from a silicon piezoresistive wafer, a stainless steel diaphragm, and a ceramic substrate, ensuring robustness and compatibility with various media. Key performance parameters include a pressure range of 0–10 bar, accuracy of ±0.25% FS, operating temperature from -40 to 85 °C, and an output signal of 4–20 mA. Response time is ≤10 ms, long-term stability is ±0.1% FS/year, and supply voltage ranges from 9–36 V DC. The element withstands proof pressure of 2× FS and burst pressure of 3× FS, with ingress protection rated IP65–IP67 depending on connector. Wetted parts are typically 316L stainless steel (Hastelloy C276 optional), and weight is ≤200 g without cable. These specifications serve as reference ranges; actual values must be confirmed for the specific model and application. The sensing element is designed for integration into OEM transmitters and gauges, and its performance is verified through calibration and testing. For procurement, it is essential to verify model-specific values and standards with the legal manufacturer or supplier to ensure suitability for the intended use.

Working Principle

Pressure-induced deformation changes electrical properties (resistance, capacitance) of sensing material, generating proportional voltage or current output. In piezoresistive elements, a diaphragm deflects under pressure, altering the resistance of implanted piezoresistors. Capacitive elements change the gap between plates, varying capacitance. Strain gauge elements use bonded gauges whose resistance changes with strain. The resulting electrical signal is conditioned and amplified to provide a standardized output, such as 4–20 mA, proportional to the applied pressure.
