AST-1015-W PPM O2 Transmitter – Wall Mount

Advanced Sensor Technology

AST-1015-W PPM O2 transmitter is 4-20mA loop-powered transmitter. The design of AST-1015-W PPM O2 transmitter lends itself to be mounted on a wall or on a post. The transmitter, when used in conjunction with an intrinsic safety barrier MTL-7706+, it complies with the intrinsic safety directives for use in hazardous areas in Class I Division I Group IIB/IIC.

The salient feature of this transmitter is that the user can select any measuring range from 5 PPM to 25% full scale in the field. The range selection does not require any change in the electronics configuration in the field. The transmitter’s LCD displays real time oxygen concentration but the user can lock 4-20mA signal output on any of the selected range. The sensor’s recovery from air to less than 10 PPM is remarkably low, just 40 minutes. Expected life of the sensor is up to 18 months at ambient temperature and pressure and oxygen concentration less than 1000 PPM.

Transmitter can be used over an extended operating temperature range of -10°C (14°F) with optional Z series PPM O2 sensor. In addition to extended temperature range, Z-Series sensor show excellent compatibility with gas streams containing any level of CO2. No routine sensor maintenance needed, except for a periodic calibration with a know oxygen standard.
