Description

Measuring/testing the benchmark for low and medium pressure measurements: Setra’s Model 239/C239 is designed for high precision inspection needs in low-pressure applications. Setra’s patented variable capacitance sensor is extremely simple in construction. It consists of a stainless steel diaphragm and a fixed electrode to form a variable capacitor. When the pressure changes, the capacitance value also changes. The capacitance is detected and determined by Sit. (Setra) A unique electronic circuit converts it into a linear DC signal. Its unique structure allows it to withstand high static and differential pressure overloads. Excellent precision, long-term stability, and fast dynamic response make this series of products ideal for differential pressure measurement in many fields such as aerospace, meteorology and scientific research.
