• Flow monitoring of gaseous media
in hazardous areas
• Installation in Zone 2 (gas) or Zone 22 (dust)
• PNP switching output resp. analog output
• On-site adjustment of detection range
The air flow monitor LC 500 EX22 detects air flows in exhaust and supply air lines in areas requiring sensors of Ex device category 3. The sensor impresses with its intuitive operation: With a potentiometer, the sensor is set to the limit value at a specified air flow. A 3-colour illuminated dot signals the flow status, which is also output via the PNP switching output for further processing to a control system. In addition, devices with analog output are available.
