Capacitive Pressure and Density Transmitter TDFX-11303

The pressure measurement system by capacitive sensor enables the reading of differential pressures. By means of an oscillator, connected to the capacitors, the reading is performed without the need for A/D converters, resulting in high precision and repeatability;
Low maintenance, easy calibration and setup;
Easy installation directly on pressurized vessels;
HART technology provides easy configuration and diagnostics during operation;
Easy installation, flanges, ASME B16.5 or ISO 1127 sanitary triclamp.
