Product catalog summary

Product Overview
The PAS Photoacoustic Gas Sensor for Ethylene (C2H4) by smartGAS Mikrosensorik GmbH is designed for continuous operation and can be self-controlled or partially controlled via a connected PLC. It features a compact design, zero-calibration by external command or automatically, and continuous data access via UART. The sensor compensates for water vapor cross-sensitivity and indicates status through an LED.

Applications
This sensor is suitable for gas analysis, biogas applications, environmental monitoring, process control, and emission monitoring. Available equipment includes a gas cooler, particle filter, gas pump, mounting equipment, and galvanically isolated output.
