The APG PT-400 pressure transducer offers high accuracy and reliability over a wide range of pressures. The small size, integrated electronics, wide operating temperature range, Intrinsically Safe approvals, and durability make the PT-400 the perfect instrument for static and dynamic pressure measurements with an amplified output signal. It's built for harsh environments, high vibration, high-pressure spikes, and even extended temperature compensation.

The PT-400 is certified compliant with Class 1, Zone 0 requirements in North America, ATEX in Europe, and IECEx for just about anywhere else. So it's ideal for markets like the oil and gas or water and wastewater industries that deal with flammable gases.

A Modbus RTU output on the PT-400 pressure transmitter is compatible with any Modbus PLC or controller.
