ABB Differential Pressure Transmitter 266MST FCKA6J1 B4M1T1CC

The ABB 266MST pressure transmitter utilizes a multisensor technology to measure differential and absolute pressure simultaneously. It employs a pressure sensor that converts the pressure difference into an electrical signal. This signal is then processed and used to determine the differential and absolute pressure readings. The transmitter also incorporates temperature and absolute pressure sensors to compensate for environmental effects on the main pressure sensor, ensuring accurate and stable measurements.
