USA Setra Pressure Sensor 730G020TAN22CT1A Product Details:
product description
Setra's Model 730 is a high-precision capacitance manometer (also called a capacitance diaphragm manometer (CDG)) for measuring
volts, low vacuum pressure ranges critical for process control in the semiconductor and industrial markets. Its 0.5% reading accuracy and precise
The 730 is made of all Inconel® wetted materials, making it compatible with semi-
The 730's direct measurement design allows accurate measurement of the media, regardless of the gas or corrosive media in the application.
What is the composition of the mixture.
High performance for demanding applications - The Model 730 Capacitance Manometer uses a single diaphragm variable capacitance sensing element for
Its percentage of reading accuracy, high resolution and wide dynamic range make the 730
Ideal for critical manufacturing processes.
Designed with Inconel® Versatile Compatibility - All wetted parts of the 730 are designed from Inconel®.
Inconel® is highly resistant to aggressive media used in semiconductor and industrial vacuum processes.
And the fully welded structure ensures long service life in application.
Direct pressure measurement - The Model 730 is designed with a diaphragm to measure pressure changes directly at the point of use.
Unlike the 730, which measures direct pressure; it is independent of the gas mixture being measured. This makes the 730 more efficient than a 100-meter flowmeter that only measures indirect pressure.
The pressure gauge has higher accuracy.

Setra's Model 730 Capacitance Manometer is a temperature compensated absolute pressure sensor designed for accurate and repeatable vacuum measurements. A variety of full scale ranges are available from 10 Torr to 1000 Torr. Units of measurement can be specified in Torr (mmHg), millibars, kilopascals, or PSIA.
The Model 730 operates from a 12-30 VDC supply and provides a 0-10 VDC signal output that is linear with pressure and independent of gas composition. It can also provide a 0-5 VDC output that is powered from a 9-30 VDC supply. The Model 730 is pin compatible with competing capacitance manometers. Superior EMI/RFI performance is achieved through the use of a metal housing as well as surge and ESD suppression components and RFI filtering on the input and output. The Model 730 features easy access to a multi-turn potentiometer for fine zero adjustment. Inconel is used for all wetted materials for compatibility with corrosive gases. A wide variety of process connections are available.
The high-precision pressure sensing element used in the Model 730 is a variable capacitance sensor from Setra. The centrally located feedthrough assembly supports a circular electrode adjacent to the back of the diaphragm. Together, the electrode and diaphragm
A variable capacitor is formed within a small reference vacuum chamber. As pressure increases, the diaphragm deflects and the gap between the electrode and diaphragm decreases, causing the capacitance to increase. This change in capacitance is detected by Setra's high frequency precision diode bridge circuit and converted into a high precision linear DC electronic signal.
Excellent zero stability and barometric pressure insensitivity are achieved through a patented sensor design. The Model 730 sensor contains no fragile or complex parts found in ceramic capacitance manometers. All-welded construction eliminates stability issues inherent in other designs due to frictional contact between dissimilar materials.
Setra Systems, Inc. was founded in 1967 by brothers Dr. YT. Li and Dr. S.Y. Lee, both professors of engineering at MIT and co-developers of the variable capacitance transduction principle.
Building on this tradition of innovation, we continue to design and supply sensing devices for many different applications and industries – delivering innovative solutions for HVAC and Building Automation, Industrial OEMs, Test and Measurement, and Critical Environments.
Since 1996, our corporate headquarters and primary manufacturing facility have been located in the town of Boxborough, Massachusetts, 25 miles northwest of Boston.
Setra is part of the Forive Group of Companies, a diversified industrial growth organization headquartered in Everett, Washington, with 26,000 employees worldwide. The Fortive Business System (FBS) is the cornerstone of our culture and our ultimate competitive advantage. It drives every aspect of our work, strategy, and performance. We use the FBS to guide our decisions, measure our ability to execute, and develop innovative ways to do better.
