AST-1015-W PPM O2 4-20 mA Loop-Powered Transmitter – Wall Mount

AST-1015-W PPM O2 transmitter has a wall-mounting enclosure, specifically designed for easy in-line mounting around the Gloveboxes. AST-1015-W 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-W 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-W 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.
