Future inside – smart environmental sensing technology

by G. Lufft Mess- und Regeltechnik GmbH  (Jun. 24, 2015)

SHM30 snow depth sensor in Antarctica (photo: Alfred-Wegener-Institut, Helmholtz-Zentrum Bremerhaven) A lot of sensing technologies have changed recently: Ultrasonic wind measurement replaces cups and vane systems, closed anemometer designs offer better protection from ...

Monitoring network for Scottish ports - Case Studies

by OTT Hydromet  (Jul. 2, 2015)

Historically, ferry masters operating off the west coast of Scotland would have to sail to a port and on arrival visually assess the weather and tide conditions before deciding whether safe berthing alongside the pier or quayside would be possible. This wastes time and fuel, and can causes immense frustration among passengers, who may see ferries ...

Real time determination and monitoring of biofilm in cooling systems 1. KEYWORDS HydroBio® Advance, Cooling system, Biofilm, Biocide consumption 2. BACKGROUND This case study shows how the application of the HydroBio® Advance is used to evaluate the real biocide demand of a cooling system in the petrochemical industry. ...

4- Step Guide to Choosing the Right Temperature Sensor

by CAS DATALOGGERS  (May 29, 2012)

Temperature measurements are among the most common data logging applications found across a broad variety of industries including medical monitoring, cold chain integrity, machine monitoring, and many more. There are 4 main types of temperature sensors that are used with data loggers, and it can seem like a lengthy decision to find the right type. ...

Group method of data handling and neural networks applied in temperature sensors monitoring

by Inderscience Publishers  (Aug. 22, 2011)

In this work a monitoring system is developed based on the Group Method of Data Handling (GMDH) and Artificial Neural Networks (ANNs) methodologies. GMDH creates non-linear algebraic models for system characterisation and ANN is a massively parallel distributed processor made up of simple processing units called neurons. The monitoring system was ...

Accuracy in temperature sensor response time estimation for new nuclear reactor designs

by Inderscience Publishers  (Mar. 29, 2011)

One method for measuring the response time of temperature sensors, the plunge test, verifies that the sensor has a suitable response time in the laboratory before installation. However, plunge test results cannot be extrapolated to the response time in an operating plant because response time is affected by multiple factors such as the ratio of ...

Flow Profiling on Demand – Illuminating the reservoir with Silixa’s intelligent Distributed Acoustic Sensor (iDAS) and ULTIMA Distributed Temperature Sensor (DTS)

by Silixa Ltd  (Mar. 22, 2013)

As energy demands increase rapidly, the goal of energy companies is to maximize ultimate recovery in an economically sound manner. One critical capability is the accurate measurement and monitoring of production from individual layers / perforated intervals in a multi-zone completion. This data allows operators to optimize zonal production, ...

PT sensors

by madur Polska Sp. z o.o.  (Apr. 1, 2014)

Temperature detectors based on the phenomenon of metal resistance changes with the change of temperature are probably the most popular type of temperature sensors used in industry sector. Most popular temperature resistors are based on platinum and nickel. Historically the first sensor made was the platinum sensor with the resistance of 100#1; and ...

Dissolved oxygen measurements in aquatic environments: The effects of changing temperature and pressure on three sensor technologies

by Soil Science Society of America  (Apr. 28, 2008)

Dissolved oxygen (DO) is probably the most important parameter related to water quality and biological habitat in aquatic environments. In situ DO sensors are some of the most valuable tools used by scientists and engineers for the evaluation of water quality in aquatic ecosystems. Presently, we cannot accurately measure DO concentrations under ...

Response time testing of temperature sensors using loop current step response method

by Inderscience Publishers  (Feb. 20, 2013)

The Loop Current Step Response (LCSR) method is used for in–situ response time testing of temperature sensors as installed in an industrial process. This paper presents the theoretical foundation of the LCSR (test theory, LCSR equation and test procedures) and the author's research to validate its use in nuclear power industry applications. ...
