Temperature-data logger

Detailed monitoring (e.g., by temperature data loggers) may be necessary for... 

The use of calibrated electronic temperature-data loggers have many advantages over the use of minimum/maximum thermometers as the course of the temperature over time can be measured and recorded. 

Data Logger it acquires the external plant parameter signals (e.g. load steam flow, temperature and pressure etc.) required for correlation with the AE activity. 

An evaluation of the HVAC system may include limited measurements of temperature, humidity, air flow, as well as smoke tube observations. Complex investigations may require more extensive or sophisticated measurements of the same variables (e.g., repeated COj measurements taken at the same location under different operating conditions, continuous temperature and relative humidity measurements recorded with a data logger). 

The water samples were analysed for pH, electrical conductivity (EC), temperature (T), dissolved oxygen (DO), redox potential (Eh), reduced iron (Fe2+) and alkalinity (dissolved inorganic carbon, DIC, as HC03") in the field. A few special water samples were collected to determine background levels of CD4, SF6 and Kr in the headspace gas. SWL and T were recorded hourly in 3 shallow (Sites H, I, R) and 3 deep (Sites J, V, W) open bores using automatic data loggers, which were downloaded biannually. 

Sensors were inserted in the prototype to monitor the temperature (National Semiconductors, LM35-DZ), humidity (Honeywell, HIH-3605-B) and total VOC concentration (FIS, SP3-AQ2) at various locations shown in Fig. 12.8-10. The data were collected by a data logger (Picolog, ADC-16) and analyzed. The temperature profiles from the preliminary test showed that poor seal between the hot and cool air streams compromised the prototype performance. Hot spots and uncontrollable temperature rise prevented further tests. This clearly showed that the complicated design is not suitable. 

The need to transport temperature-sensitive raw materials and products, such as cell line, medium, large molecule drugs, and vaccines, means that some form of control during transportation is needed. For example, a working cell bank for the production of proteins may be transported in liquid nitrogen (-196 °C) and that of protein and vaccines in dry ice (-78 °C) in order to protect the integrity of the materials. Data loggers are used to record the temperature...

On the air side calibrated thermocouples to measure temperature at different locations in the cell two capacitive hygrometers on the evaporator a humidity controller designed to deliver a maximum vapor flow rate of lOkg/h have been installed. A liquid flowmeter to measure the volumetric flow rate of the aqueous desiccant solution at the membrane contactor outlet was used. All instruments are connected to a data logger. 

The whole apparatus is rated for a pressure of 330 atm. All measured temperatures and pressures are recorded on a data logger at regular time intervals. The SCF-solid mass transfer coefficients were measured as a function of flow rate and pressure (or density). The ranges of system parameters examined in this study are shown in Table I. 

Salinity-Temperature-Pressure (Depth). Conductivity, temperature and pressure data were collected using a Plessey Systems CTD with model 8400 data logger. These sensors were interrogated five times per second for values of temperature, conductivity (salinity), and pressure (depth). Data were recorded during the down-cast using a lowering rate of 30 m min". Niskin bottle samples were taken on every other cast to provide temperature and salinity calibration. Nominal precision of the salinity, temperature and depth measurments was 0.02 g kg", 0.02 °C and 0.2 m, respectively. 

An assessment of drop-impact damage risks can be made by direct observation, self-contained instruments (within packs), and special recording instruments to identify how simulated laboratory tests can ultimately be substituted for travel tests. Data loggers are now capable of recording temperatures, RH, impacts and vibrations. 

Surface sediment samples were collected from Loch Sunart, a sea loch (fjord) on the NW coast of Scotland, during cruises aboard the R. V. Clupea (April 1999) and the R. V. Envoy (July 2001 and June 2002). Bottom water temperature and salinity measurements were recorded using a STD Plus 646 conductivity, temperature and depth (CTD) probe at each sample site (Table 1). No data were collected on pH and carbonate ion concentration. Two stationary Anderaa RCM-7 current meters complete with temperature and conductivity sensors and a data logger were deployed in the inner basin (56.6842°N, -5.6211°W) between 21 June 2001 and the 18 June 2002, and the main... 

High Ambient and Off-Gas Temperatures Water cooling was employed for the launch and receiver modules, the pathlength control probes, and the break flange. A total of six thermocouples were used during the first several months of operation to monitor the thermal conditions of the optics modules and probes. Thermocouple data was recorded on a separate data logger located near the measurement location. Each module had an internal thermocouple, a thermocouple to measure enclosure water outlet temperature, and a thermocouple to monitor the water outlet temperature of each probe. 

Temperature and humidity measuimnents were taken by means of data loggers (Gemini TINYTALK II), run using the Orion Tiny Logger Manager (OTLM) for... 

Windows as the host software. The data loggers were able to measure difierraces in temperature and humidity via a probe, or sensor. OTLM set the loggers up to start logging and then to offlo the data from them afterwards. 

As the first stage is run, informatiou is automatically recorded (with a data logger) concerning temperature, torque and filtrate weights. Thus, in one run filtrate rates can be obtained as a function of solids concentration. 

Some data loggers are able to indicate whether the temperature fall below 2 °C or rises over 8 °C by a light signal.
