Dewpoint - Transmitters

 

The HygroPro is a loop-powered, intrinsically safe moisture transmitter for measuring the moisture content in gases and non-aqueous liquids in pipeline natural gas, petrochemical, power generation, pharmaceutical, process, and industrial applications. The HygroPro features an aluminum oxide moisture sensor, temperature thermistor, and pressure transducer built on a single probe mount to provide real time measurements for the calculation of parameters such as ppmv in gases, pounds per million standard cubic feet in natural gas, ppmw in liquids and percent relative humidity in addition to dew point temperature.

The MMY30 is specifically designed to measure dew point or ppm at line pressure or atmospheric pressure for control of desiccant air dryers. These benefits apply to both dryer users and manufacturers.

  • Simple, 4-20 mA two-wire connection

  • Fast response planar sensor

  • Integral filtering and flow regulation

  • Trouble-free indoor or outdoor mounting

  • Field calibration with the optional DewComp(MCY40)

  • Microprocessor in NEMA 4X (IP66) enclosure

  • FM approval (Class 1) – Division 2 standard

The MMY31 mounts directly in-line for applications such as glove boxes, where a bypass is not appropriate. It is easily installed via a 1/2" MNPT or G 1/2 adjustable insertion length compression fitting. Applications include glove boxes, environmental chambers, and high altitude testing.

  • 4 to 20 mA loop-powered 1/2" MNPT or G 1 / 2 process connection Planar capacitive sensor

  • Class 1, Division 2 standard


The Veridri Moisture Transmitter provides Dryer Manufacturers and other OEM's with the means to make simple accurate and reliable moisture measurements with a wide variety of Dewpoint ranges.

  • 4 to 20 ma loop powered

  • 3/4-16 Straight thread with optional 3/4" NPT adapter

  • Thin Film Aluminum Oxide Technology

  • General Purpose

Dew-10 Series
Transmitters Dew-10 Series - GE General Eastern Description The Dew-10 Series is a family of low cost, high performance chilled mirror dew point transmitters comprising pipe, duct, and wall mount models. All models provide accurate and reliable dew point measurements over a wide range for energy management and process applications. Accuracy for the series is +/- 0.5ºC (+/- 1ºF). Dew point may be measured over a range of -40º to +58ºC (-40º to +136ºF). The wall mount version is also available with an optional air temperature measurement capability over the same range.


Features and Benefits:

  • Fundamental dew point measurement

  • High Accuracy

  • Wide operating range

  • Low-cost design

  • Outputs: dew point and optional ambient air temperature.

Precision Duct Mounted Humidity Transmitter with Integrated Chilled Mirror Sensor

  • Utilizes the time proven single stage 1111H chilled mirror sensor

  • Sensor fully recovers from condensation

  • Direct primary dew point measurement. NIST traceable.

  • Provides linear 4-20mA Signal

  • RS-232 Interface

  • Equipped with patented PACER self-cleaning & optical balancing system

  • Sensor wetted components are inert. Optional platinum mirror for more aggressive environments.

  • High accuracy: ± 0.2° C dew/frost point

  • No long-term drift

  • Equipped with membrane filter

  • Mirror is easily accessible for manual cleaning

  • Optional temperature or pressure sensor input for %RH, absolute humidity or mixing ratio
