HUMIDITY 09.18 10/2008 We reserve the right to make technical changes. 09 www.ahlborn.com ALMEMO® dew-point sensor, type FHA646DTC1 Dew-point transmitter with current output MT8716DTC1 .. Especially suitable for dew-point measurement with high level precision and long-term stability. .. Digital transfer of measured values to the ALMEMO® display section (avoids risk of inaccuracy on the connecting lines or in the display section itself). .. High-level accuracy sustained down to -80 °C. .. High-speed reaction time. .. Displayed variables : temperature, rel. humidity, dew-point. .. Process connection for high pressures (optionally up to 350 bar). Technical data : Measuring range -80 to +20°C dew-point temperature (DT) Measuring accuracy ± 0.5°C from -10 to +20 °C DT, typical ± 2°C at -40 °C DT Measuring channels (FHA646DTC1 only) Temperature -20.0 to +70.0 °C Relative humidity 0 to 98.0% RH Dew point -80.0 to +20.0 °C dew-point temperature (DT) Operating temperature -20 to +70 °C Process connection Screw thread G 1/2”, stainless steel Protective cap Sintered stainless steel filter Pressure range -1 to +50 bar standard Storage temperature +40 to +80 °C FHA646DTC1 Output ALMEMO® digital Power supply via ALMEMO® connector, approx. 5 mA Connection Cable, 1.5 meters, with ALMEMO® connector MT8716DTC1 Output 4 to 20 mA / -80 to +20 °C dew-point temperature (DT), 2 wires Power supply 10 to 30 V DC, load <500 ohm Connection Transmitter connector Housing Material polycarbonate Protection system IP65 Types (including manufacturer’s test certificate) ALMEMO® dew-point sensor with connecting cable, 1.5 meters long, and ALMEMO® connector Order no.
