Humidity and Dew-Point Instruments Easidew I.S.

1 Humidity and Dew-Point Transmitter(For Hazardous Area Applications)The Easidew (intrinsically safe) transmitter is a Dew-Point transmitter designed and certifi ed for use in hazardous area applications (fl ammable or explosive gases) in all regions with certifi cation from: IECEx, CSA, FM and Easidew is available with a choice of G1/2" BSP, 3/4" or 5/8" UNF process connections. It is designed for ease of use, incorporating all of the features needed to make installation and operation into your air or gas management system as simple as 's Advanced Ceramic Moisture Sensor technology based transmitter is calibrated to international standards and is delivered with a traceable calibration certifi IECEx, CSA, FM, ATEX certifi ed transmitter for use in hazardous areas G1/2" BSP, 3/4" or 5/8" UNF process connection Dew-Point or ppmV moisture content 2-wire loop powered connection Rugged 316 stainless steel IP66 construction Measurement range -100 to +20 C Accuracy 2 Cdp Calibration Certifi cate (NPL, NIST)Technical Specifi cationsPerformanceMeasurement range-100 to +20 C dew pointAccuracy 2 C dew pointResponse time5 mins to T95 (dry to wet) C dew pointCalibrationTraceable 13 point calibrationElectrical Specifi cationsOutput signal4-20 mA (2-wire connection, current source)
