Humidity and Dew-Point InstrumentsPrecision Manufacturing<strong>Easidew</strong> Transmitter2-Wire Dew-Point TransmitterThe <strong>Easidew</strong> Transmitter is designed for ease of use,incorporating all the features needed to make installationand operation as simple as possible. For the first time, dewpointmeasurement is made as accessible as temperatureand pressure with this fully configured, calibratedtransmitter that can be instantly incorporated into your airor gas management and control system.Highlights• 2-wire loop powered connection• Dew point or ppm moisture content• IP66 (NEMA 4)• Excellent sensor protection• Measurement range -100 to +20°C / -148 to +68°F• Operating temperature -40 to +60°C / -40 to +140°F• Fast responseDimensionsTechnical SpecificationsMeasurement range (dewpoint)Accuracy (dew point)Response timeRepeatabilityOutput signalSupply voltageLoad resistanceCurrent consumptionSupply voltage influenceOperating humidityOperating temperatureOperating pressureFlow ratePerformance-100 to +20°C / -148 to +68°F dewpoint±2°C / 3.6°F dew point5 mins to T95 (dry to wet)0.5°C / 0.9°F dew pointElectrical output/input4-20 mA (2-wire) current source,configurable over the entire rangeDew point -100 to + 20°C-150 to +70°F0 - 3000 ppm vppm voutput or non-standard dew-pointrange must be specified at time oforder12–28 VDCMax 250 Ω @ 12 V500 Ω @ 24 V23 mA max (fault condition)±0.005% RH/VOperating conditions0–100% RH-40 to +60°C / -40 to +140°F6500 psi / 450 bar g max
