1: Product Overview
The SCYG4104 differential pressure transmitter is suitable for differential pressure measurement of any gas or liquid medium that is non corrosive to 316 stainless steel, with good medium compatibility. The product uses a pressure resistant OEM pressure sensor with a stainless steel isolation membrane as the signal measurement element, and utilizes proprietary technology to compensate for the zero temperature performance of the OEM pressure sensor over a wide temperature range, maximizing the overall temperature impact of the pressure transmitter. The signal processing circuit is located inside a stainless steel casing and converts sensor signals into standard output signals. The entire product has undergone strict testing and aging screening of components, semi-finished products, and finished products, as well as multiple moisture-proof treatments with three proof paint, ensuring stable and reliable performance.
This product is widely used for pressure measurement and control in industrial process sites such as petroleum, chemical, metallurgical, power, and hydrological industries due to its excellent reliability, flexibility, and diversity. Multiple connection ports are available for selection, and can also be customized according to user needs.
