Description
The GS4700 series is a compact, rugged pressure transducer designed for accurate measurement up to 100 bar (1450 psi), using piezoresistive silicon sensor technology for stable, repeatable performance in demanding environments. Available in both gauge and absolute pressure configurations, it features stainless-steel construction and supports multiple output signals, making it ideal for industrial systems, OEM integration, and aerospace applications where reliable pressure monitoring and system compatibility are essential.
Supported by SUCO ESI North America’s exceptional technical service, customers also benefit from expert guidance and customized solutions designed for their specific application requirements.

Difference between absolute pressure and gauge pressure:
Absolute pressure is a pressure that is relative to the zero pressure in the empty, air-free space of the universe. This reference pressure is the ideal or absolute vacuum. It is denoted with the subscript “abs”: Pabs.
The gauge pressure is defined as the difference between an absolute pressure (Pabs) and the prevailing atmospheric pressure (Pamb). It is denoted with the subscript “e”: Pe and is calculated as follows: Pe = Pabs – Pa
