Pressure Transmitter: Digital Pressure Transmitter with Auto Compensation - ±0.025% - 100:1 Turndown

Introduction

Pressure readings that drift with temperature force frequent recalibration and doubt in process data. The APT digital pressure transmitter with automatic compensation corrects temperature and zero drift on its own and holds ±0.2% of URL over 15 years.

Key Benefits

How the APT Digital Pressure Transmitter helps your daily work:

Efficiency

4-20 mA, Modbus and wireless options fit straight into existing control systems.

Accuracy

Automatic temperature and zero drift compensation keep readings within specification from -50 to +85 °C.

Safety and comfort

A fully welded sensor resists leaks on high-pressure lines.
