PTDM Pressure Transducer

Product Description

Edgetech Instruments Pressure Transducer is designed for accurate pressure measurement of gases or liquids compatible with stainless steel. The high level output signal requires no additional signal conditioning and results in excellent stability, accuracy, and fast dynamic response, making the Model PTDM ideal for high performance applications.

The stable electronic circuit, combined with Edgetech’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 electric signal.
