III.—On a New Hygrometer or Dew Point Instrument

Dew point measurement using a sensitive circuit type of dew point sensor

Received: 13 Mar. 2012; Revised 25 Jul. 2012; Accepted 04 Aug. 2012 Received: April 8, 2012; Revised May 4, 2012; Accepted June 6, 2012 Abstract: Aiming at the problem of atmospheric humidity measurement, this paper proposes a method to measure dew point based on sensitive circuit for the first time. We use the quartz crystal in the Colpitts circuit as the humidity sensitive element. Since the ...

Constant Dew Point Corrosion Tests for Metals

A micro dew point sensor with a thermal detection principle

We present a dew point temperature sensor with the thermal detection of condensed water on a thin membrane, fabricated by silicon micromachining. The membrane (600 × 600 ×∼1 μm3) is part of a silicon chip and contains a heating element as well as a thermopile for temperature measurement. By dynamically heating the membrane and simultaneously analyzing the transient increase of its temperature i...

Doing More with the Dew: A New Approach to Cloud-Dew Architecture

While the popularity of cloud computing is exploding, a new network computing paradigm is just beginning. In this paper, we examine this exciting area of research known as dew computing and propose a new design of clouddew architecture. Instead of hosting only one dew server on a user’s PC — as adopted in the current dewsite application — our design promotes the hosting of multiple dew servers ...

The measurement of tiny dew droplets at the initial deposition stage and dew point using a phase-shift interference microscope

The shape of a dew droplet deposited on the mirror surface of a copper plate was measured accurately using an interference microscope that employed a phase-shift technique. The microscope was constructed by adding a piezoelectric transducer to an interference microscope. A simple method that uses a conventional speaker horn and an optical fibre cable was used to depress any speckle noise. The s...
