How the NT3051 Differential Pressure Transmitter Works

The NT3051 measures the pressure difference between two process connections using a high-performance differential pressure sensing element.

The pressure difference is converted into a digital signal by an intelligent microprocessor, which automatically compensates for temperature drift, nonlinearity, and sensor errors to provide highly accurate measurements.

Depending on the installation method, the NT3051 can be used for:

• Differential pressure measurement
• Flow measurement with primary flow elements
• Hydrostatic liquid level measurement
• Density measurement
• Pressure monitoring

The integrated LCD display allows local configuration of zero point, measuring range, and operating parameters without additional calibration equipment.
