Dew Point Sensor
CS-Instruments FA 500
Dew point sensor with integrated display and alarm relay
Overview:
Ideal for all types of compressed air dryers with different measuring ranges such as -80...+20°Ctd; -60...+30°Ctd; -20...+50°Ctd
Sensor element insensitive against condensation and water
Maximum pressure 500 bar (special version)
Long-term stable and drift-proof, thus optimized calibration intervals
Gas-independent measurement, also suitable for other non-corrosive gases
Fast response time, especially in case of moisture ingress
BSP- or NPT-Threads
Protection class IP 65
Analog output 4...20 mA and Modbus RTU (RS 485) interface, contact relay with limit value adjustable via keys (max. 60 VDC, 0.5A)
Optional: Modbus TCP (Ethernet), Modbus TCP PoE (Ethernet) or M-Bus interface
Measured values available in different units, pressure dew point [°Ctd], temperature [°C], rel. humidity [%rh], abs. 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 with handheld device or CS Service Software
With the FA 500 you make the right choice for highest precision in dew point measurements. Our sensor offers a wide span of measuring ranges perfectly matched to the needs of different compressed air dryers. Rely on us for accurate results in any situation.
Monitoring a compressed air dryer is critical to increase energy efficiency, ensure product quality, prevent machine damage, identify maintenance needs and achieve cost savings. This contributes to the smooth operation of compressed air systems in various industrial applications.
Multiple display pages to show dew point and other measured values such as relative humidity and temperature
Definition of threshold values for the alarm relay, definition of hysteresis
Scaling of the analog output 04...20 mA and switching to other measured variables
Input of system pressure as well as reference pressure for calculation of reference dew points, e.g., atmospheric dew point
