Technical overview
AST-1015 PPM O2 transmitter is specifically designed for easy in-line mounting around the Gloveboxes. AST-1015 PPM O2 transmitter comes with 316 SS sensor housing and fittings. The transmitter does not require any external sample system. Its design meets the intrinsic safety requirements when used in conjunction with an intrinsic safety barrier MTL-7706 or equivalent. The salient feature of the transmitter allows the user to select any analysis range between 0-5 PPM and 0-25%. The 4-20mA signal output from the transmitter is locked on the selected analysis range. The proprietary oxygen sensor used in the transmitter speeds up the recovery from higher oxygen levels to low oxygen levels, for example, the recovery from air to 10 PPM is under 45 minutes.
AST-1015 PPM O2 transmitter offers the user the flexibility to selectable any analysis range in the field. The provision of fine-tuned temperature compensation feature ensures that the transmitter’s measurement accuracy is not compromised even in varying ambient conditions. The user-selectable digital filter provides optimum signal to noise ratio with acceptable system response time to any step-change in oxygen concentration. The transmitter is provided with a standard PPM O2 sensor, Model AST-333. This sensor is ideal for measuring oxygen in inert and gaseous hydrocarbon gas streams.
AST-1015 PPM O2 transmitter can be used in lower operating temperature range, for example, down to -10°C (14°F). However, this requires the Z-series O2 sensors. The Z-series sensor model AST-333Z PPM O2 sensor not only extends the lower operating temperature range but also shows excellent compatibility with gas streams containing any level of CO2 gas. No routine sensor maintenance is needed. The transmitter designed and built in the USA.
Applications and guidance
Advanced Sensor Technology
AST-1015 PPM O₂ Transmitter
AST-1015 PPM O₂ Transmitter is designed for easy in-line installation around gloveboxes and gas delivery systems. Because of its compact design, users can mount the transmitter directly in the process line without an external sampling system.
The transmitter includes a 316 stainless steel sensor housing and fittings, which provide excellent corrosion resistance and durability. In addition, the unit does not require an external sample system, which simplifies installation and reduces overall system cost.
Moreover, the transmitter meets intrinsic safety requirements when used with an MTL-7706 intrinsic safety barrier or equivalent. Therefore, it can operate safely in hazardous environments where explosion protection is required.
A key feature of the transmitter is its field-selectable analysis range. Users can select any range between 0–5 PPM and 0–25% oxygen. At the same time, the 4–20 mA output signal automatically locks to the selected analysis range, which ensures stable and accurate signal transmission.
The transmitter also uses a proprietary electrochemical oxygen sensor that improves recovery from high oxygen levels. For example, the sensor recovers from air to 10 PPM in less than 45 minutes, allowing faster return to trace oxygen monitoring conditions.
Furthermore, the AST-1015 transmitter offers fine-tuned temperature compensation. As a result, the instrument maintains measurement accuracy even when ambient temperature conditions change. In addition, users can enable a digital filter to optimize the signal-to-noise ratio while maintaining an acceptable response time during changes in oxygen concentration.
The transmitter operates with the AST-333 PPM oxygen sensor, which measures oxygen in inert gases and gaseous hydrocarbon streams. This sensor provides reliable performance for glovebox monitoring and process gas analysis.
For applications requiring lower operating temperatures, the transmitter can operate down to -10 °C (14 °F) when used with the AST-333Z Oxygen Sensor. In addition to extending the operating temperature range, this Z-series sensor shows excellent compatibility with gas streams containing any level of CO₂.
Finally, the AST-1015 transmitter requires no routine sensor maintenance, which helps reduce operational downtime. The transmitter is designed and manufactured in the United States by Applied Sensing Technologies, ensuring dependable quality and performance.
