AST-1015-P % Oxygen Transmitter – 4-20mA Loop-Powered

AST-1015-P % Oxygen Transmitter

The AST-1015-P % Oxygen Transmitter from Applied Sensing Technologies is a two-wire, 4–20 mA loop-powered transmitter designed for reliable oxygen monitoring in industrial processes. Because of its compact design, users can install the transmitter directly on the process pipe, which simplifies installation and reduces system complexity.

The AST-1015-P % Oxygen Transmitter meets intrinsic safety requirements when used with an MTL-7706 safety barrier or equivalent. Therefore, it can operate safely in hazardous environments where explosion protection is required.

In addition, the transmitter allows user selection of any analysis range from 0.5% to 25% oxygen. The 4–20 mA signal output automatically locks to the selected analysis range, which ensures stable and accurate signal transmission to control systems.

The transmitter enclosure meets IP66 protection rating, which protects the unit from dust and water ingress. Furthermore, the transmitter design resists high-voltage transients associated with lightning, ensuring dependable operation in demanding environments.

The transmitter also delivers fast sensor response and recovery. For example, the oxygen sensor recovers from air to 0.1% oxygen in less than 30 seconds, which makes the instrument well suited for continuous process monitoring.

Moreover, the AST-1015-P transmitter can operate in an extended temperature range down to -10 °C (14 °F) when used with Z-series oxygen sensors. These Z-series sensors also provide excellent compatibility with gas streams containing any level of CO₂, which improves measurement reliability in CO₂-rich environments.

Finally, the transmitter requires no routine sensor maintenance, which helps reduce downtime and overall operating costs.
