FA 510/515 – Dew point sensor for refrigeration dryers

• Ideal for refrigeration dryer applications with an accuracy of +/- 1°C in the measuring range -20…+50°Ctd.
• Gas-independent measurement, also suitable for other, non-corrosive gases
• Compact design, ideal for dryer installations
• Robust design, protection class IP 66
• Condensation insensitive sensor element
• Long-term stability and drift-resistant, thus optimized calibration intervals
• Fast adaptation time, especially from dry to wet conditions
• BSP, NPT or UNF thread
• Analog output 4…20 mA (two- or three-wire) and Modbus RTU (RS 485) interface
• Measured values available in different units, pressure dew point [°Ctd], temperature [°C], rel. humidity [%rh], abs. humidity [g/m³], degree of humidity [g/kg], humidity fraction V/V [ppmV/V], water vapor partial pressure [hPa], atmospheric dew point [°Ctd.atm].
• On-site sensor diagnostics with handheld device or CS Service Software

Flexible use thanks to IO-Link interface

The proven FA 510 dew point sensor is now available with an IO-Link interface. The IO-Link interface enables easy integration of dew point measurement upstream of machines and systems. Optionally available with integrated pressure sensors.

Ideally suited for monitoring refrigeration dryers

Monitoring a compressed air refrigeration dryer is crucial for increasing energy efficiency, ensuring product quality, preventing damage to machines, recognising maintenance requirements and achieving cost savings. This contributes to the smooth functioning of compressed air systems in various industrial applications.

Precise and reliable sensor technology

The sensor technology and evaluation electronics of our sensors have undergone continuous improvement. This implies increased precision at varying ambient temperatures and a higher signal resolution of the sensor. Similar to their predecessor models, the new dew point sensors are characterised by long-lasting, stable and reliable measurement results. The sensor element is insensitive to condensation and is protected from direct contact with contaminated particles by the stainless steel sintered cap
