Intrinsically Safe Humidity andTemperature Measurement• Rated Eex ia IIC T6 (I/II M1 1G/D) for Zone 0 hazardous areas• Digital output of %rh and °C • Compatible with HygroFlex Industrial Transmitter• Operates as stand-alone 2 wire 4…20 mA humidity transmitter• Hi grade stainless steel construction• PTB 01 ATEX 2180ROTRONIC AG • Grindelstrasse 6 • CH-8303 Bassersdorf • Tel. +41 1 838 11 44 • Fax. +41 1 837 00 73 • www.rotronic-humidity.com®Humidity Goes Digital HygroClip IC-ExCable mounted probe for use in applicationswith high or low temperatures (-50…+200 ºC) or where installation flexibility is required. The robust stainless steel probe is available intwo lengths, 120 and 270 mm, and both arefitted with a 2 m cable. Probe mounting is by acompression fitting, see ordering information(AC1301-MEX).HygroClip IW-ExFor wall mountedapplications with anexternal stainless probe(150 x15mm Ø).HygroClip ID-ExSuitable for duct or through-the-wall installationwith a robust 250 x15 mm stainless steel probe.Temperature measuring range is 0…100 ºC,provided the electronics enclosure does notexceed the Ex temperature rating (-20…+40 ºC).HygroClip Ex is a series of probes for the measurement ofhumidity and temperature in hazardous areas, incorporatingthe latest digital signal processing and data transmissiontechnology. Suitable for connection to the HygroFlex range ofindustrial transmitters, or for use as a stand alone 4…20 mA 2 wire transmitter, the HygroClip Ex probes offer wide measu-rement ranges and flexible installation options.The Ex probes are based on ROTRONIC’s innovativeHygroClip technology, and feature a custom ASIC to providethe highest possible accuracy with features such as digitalcalibration and probe interchangeability. Each probe isconstructed throughout from high grade stainless steel, withfull IP65 protection, and can be fitted with up to 200 m ofcable to the Zener Barrier. Probes feature a replaceable filtersystem which protects the sensors from high air velocity,dust, grease etc. To comply with hazardous area standards,a Zener Barrier is required between the HygroClip Ex probesand the HygroFlex, or when used as a 2 wire 4…20 mAtransmitter, between the probe and the control or monitoringsystem.All three probes measure over the range of 0…100 %rh thanksto the well proven Hygromer humidity sensor technology whichhas excellent long term stability, high tolerance to chemicalcontamination, and withstands exposure to condensationwithout any effect on calibration stability. Temperature range is dependent on the version used, with a maximum capabilityof -50…+200 °C.Digital Ex Humidity and Temperature MeasurementStand alone humidity ortemperature transmitterOperates on a 2 wire 4…20 mAloop basis for %rh or °C(Jumper configurable).Digital Ex Humidity and Temperature ApplicationsHygroClipExConfiguration Options• SEV: Eex ia IIC T6 (1/11 M1 1G/D)• PTB 01 ATEX 2180• II IG EEx ia IIC T5• II IG EEx ia iic T6 Combined Transmitter for humidity temperature measurementHygroClip Ex used with the HygroFlex transmitter(Factory standard configuration).OIL & GASPETROCHEMICALSMININGSUBMARINESWEAPONS STORESPHARMACEUTICAL PRODUCTIONSUGAR PROCESSINGTechnical Specifications and ordering informationSPECIFICATIONS HYGROCLIP ID-EX HYGROCLIP IW-EX HYGROCLIP IC-EXHumidity measuring range 0…100 %rhTemperature measuring range t = -30…100 °C* t = -20…+40 °C t = -50…+200 °CAccuracy at 23 °C ±1.5 %rh, 0.3 KRepeatability < 0.5 %rh, 0.1 °CResponse time <15 s at 1ms-1 air velocity at 23 °CLong term stability < 1%rh, 0.1 °C per yearSensors %rh - Hygromer C94, °C - Pt100 1/3 DINAdjustment points 35, 80, 10 & 0 %rh, T0 & Tmax (digital)Electronics operating range -20…+40 °C, 0…100 %rhOutput signals Digital 4…10 mA, Analogue 4…20 mALoad Max 800? at 26 VDCPower Ui = 28 V, I i = 195 mA, Pi = 830 mV, Ci = 11 nfEnclosure IP65 Stainless steel, 150 x100 x 58mmProbe dimensions 250 x15 mmØ 150 x15 mmØ IC1 120 x15 mmØ, 2 m cableIC2 270 x15 mmØ, 2 m cableApprovals SEV: Eex ia IIC T6 (1/11 M1 1G/D), PTB 01 ATEX 2180, II IG EEx ia IIC T5, II IG EEx ia IIC T6* Subject to the electronics working within the range –20…+40 °CORDERING INFORMATIONOrder Code: Description:HygroClip ID-EX Duct mount probe for Ex applicationsHygroClip IW-EX Wall mount probe for Ex applicationsHygroClip IC1-EX Cable mount probe for Ex applications, 120 mmHygroClip IC3-EX Cable mount probe for Ex applications, 270 mmXXET-7018 Blue cable between HygroClip IC,IW,ID-EX and Zener barrier.
