FA 505 - Dew Point Sensor for OEM Applications 

FA 505 - Dew Point Sensor for OEM Applications 

Dew point sensors for measuring residual humidity in compressed air and gases:

The CS FA 505 dew point sensor with 2-wire 4...20 mA technology and RS-485 Modbus output enables reliable and long-term dew point monitoring in industrial applications such as:

• Compressed air plants (refrigeration / adsorption dryers) 
• Granulate dryers 
• Medical gases 
• Non-corrosive gases, e.g. nitrogen

Special features of the FA 505 dew point sensor: 

• Optimal design for limited space in drying systems 
• Measurement range -80...20°Ctd 
• High long-term stability 4...20 mA analog output or modbus-RTU interface 
• Resistant to condensation 
• Fast response time
• Pressure up to 350 bar (special version) 
• NEW: Higher sensor signal resolution due to improved electronics 
• NEW: On-site sensor diagnostics using a handheld instrument or CS service software
