Setra Systems Model 280E/C280E pressure transducers are intended for low to high pressure measurements of gases or liquids in applications requiring rugged packaging, high performance and affordability. The 17-4 PH stainless steel capacitance sensing element, coupled with an IC-based circuit, assures excellent accuracy and long term stability.
The stable electronic circuit, combined with Setra’s patented variable capacitance sensor, results in the ultimate in design simplicity. The sensor features a one-piece 17-4 PH stainless steel pressure sensor and an insulated electrode, which forms a variable capacitor. As the pressure increases, the capacitance decreases. This change in capacitance is detected and converted to a linear DC output signal.
The high level 0-5 VDC or 4-20 mA output signal requires no additional signal conditioning and results in excellent stability, accuracy, and fast dynamic response, making the 280E Series ideal for high performance applications.
