- Relative humidity [% RH]
- Absolute humidity [g/m³]
- Degree of humidity [g/m³]
- Moisture content V/V [ppmV/V]
- Water vapor partial pressure [hPa]
- Atmospheric dew point [°Ctd.atm]

Features

 

 

• Perfectly suited for all types of compressed air dryers with various measuring ranges such as -80...+20°Ctd, -60...+30°Ctd, -20...+50°Ctd.
• Sensor element designed to resist condensation and water ingression.
• Maximum pressure endurance up to 500 bar (special versions available).
• Long-term stability and drift-proof design, resulting in optimized calibration intervals.
• Gas-independent measurement, making it suitable for various non-corrosive gases.
• Fast response time, especially in moisture ingress situations.
• Available with BSP or NPT threaded connections.
• Protection class rated at IP 65.
• Analog output 4...20 mA and Modbus RTU (RS 485) interface, along with contact relay with limit value adjustable via keys (max. 60 VDC, 0.5A).
• Optional interfaces: Modbus TCP (Ethernet), Modbus TCP PoE (Ethernet), or M-Bus.
• Measured values accessible in various units including pressure dew point [°Ctd], temperature [°C], relative humidity [%rh], absolute humidity [g/m³], moisture content [g/kg], moisture content V/V [ppmV/V], water vapor partial pressure [hPa], atmospheric dew point [°Ctd.atm].
• On-site sensor diagnostics available with a handheld device or CS Service Software.
