The Honeywell XNXXSA1SS, part of the XNX Universal Transmitters series, is an electrochemical sensor specifically calibrated for detecting toxic levels of ammonia gas. It allows users to select a gas range between 30% and 70% of the chosen full-scale range, providing flexibility based on application needs. The default measurement range is set to 200 PPM, enabling straightforward operation under typical conditions.

For its quick detection capabilities, the sensor boasts a response time (T90) of less than 180 seconds, alongside an impressive T50 response time of under 60 seconds. This ensures prompt detection of hazardous gas levels. The sensor also supports a network of up to 32 nodes, which enhances monitoring capabilities in larger setups.

The XNXXSA1SS operates effectively within a temperature range of -20°C to 40°C, allowing it to function in various environmental conditions. The physical layer utilized is isolated RS485, providing robust data transmission capabilities at baud rates ranging from 1200 to 19.2K. It employs connectors for Sig+, Sig-, and Screen, allowing for easy integration into existing systems. Finally, the lower detectable limit of this sensor is 6 PPM, enhancing its sensitivity for critical applications.
