Dew point
FA 510/515 - Dew point sensor

FA 510/515 for residual moisture measurement in compressed air and gases
Typical applications:

Special features:• Dew point measurement in the compressed
air after adsorption dryer, membrane dryer,
refrigeration dryer• Extremely stable in the long term
• Analog output 4...20 mA for dew point• Residual moisture/dew point measurement ingases such as oxygen, nitrogen, argon...

• Condensation-resistant• Residual moisture/dew point measurement
after granulate dryers in the plastics industry• Pressure-tight up to 350 bar (specialversion)• Quick adaption time

• NEW: Modbus-RTU interface• NEW: Higher resolution of sensor signal
due to the improved evaluation electronics

Recommendation:• NEW: Sensor diagnosis on site with a portable device or CS Service Software

Mounting with standard measuring chamber forcompressed air up to 16 bar• Readable via Modbus:

Advantage: Easy installation via quick coupling
