Relative pressure sensor MCS19

absolutemembrane4-20 mA

MCS19 pressure sensor (Metal Coalesce System) is a pressure-sensing solution developed by Chinastar M&C, featuring a 17-4PH stainless steel sensing element that delivers precise and stable measurements across a wide temperature range for demanding industrial environments.

Overview
The MCS19 is based on Chinastar M&C's independent Metal Coalesce System technology. The sensor uses a 17-4PH stainless steel sensing element, offering high accuracy, low drift and robust electrical insulation. It is designed for long-term stability under harsh operating conditions and supports multiple pressure types and temperature compensation options.
