Temperature Data Acquisition.

Data acquisition systems, as the name implies, are products and/or processes used to collect information to document or analyze some phenomenon. In the simplest form, a technician logging the temperature of an oven on a piece of paper is performing data acquisition. As technology has progressed, this type of process has been simplified and made more accurate, versatile, and reliable through electronic equipment. Equipment ranges from simple recorders to sophisticated computer systems. Data acquisition products serve as a focal point in a system, tying together a wide variety of products, such as sensors that indicate temperature, flow, level, or pressure.

Some temperature signal conditioners allow users to make adjustments from a local interface such as a front panel, or from a computer interface, touch screen, or remote handheld programmer. Devices with a computer interface are often programmable, networkable, and web-enabled. Application software is used to control or monitor temperature signal conditioning from a supervisory or host computer. User-configurable software and applications that perform mathematical and statistical functions are also available. In terms of computer hardware, temperature signal conditioning devices vary in terms of random access memory (RAM) and data storage capabilities. Some temperature signal conditioners include hard drives and tape drives. Others include floppy disc drives and compact disc drives. Real-time graphing requires a monitor for the display of data as it is collected.

There are a variety of applications for temperature signal conditioners. For example, environmental applications include groundwater monitoring and pollution measurement. Automotive applications measure factors such as speed and shock. Some temperature signal conditioning devices are designed for marine use, while others meet the strict requirements of aviation, aerospace, or military applications. Temperature signal conditioning devices are also used in seismic applications such as earthquake or volcano research, and in industries such as mining. Other applications for temperature signal conditioners include meteorology, medicine, and biomedicine. Typically, general laboratory and industrial data acquisition systems do not require devices that are hardened against weather, shock, extreme heat, and other unusual conditions.

The Universal Serial Bus (USB) is a new standard for connecting PCs to peripheral devices such as printers, monitors, modems and data acquistion devices. USB offers several advantages over conventional serial and parallel connections, including higher bandwidth (up to 12 Mbits/s) and the ability to provide power to the peripheral device. USB is ideal for data acquisition applications. Since USB connections supply power, only one cable is required to link the data acquisition device to the PC, which most likely has at least one USB port.

Superficial temperature was measured using a superficial thermocouple (TX-29; Columbus Instruments, Columbus, OH). Intramuscular temperature was measured using a fine-wire, implantable type T thermocouple (TX-23-18; Columbus Instruments), which was inserted into the triceps surae through an 18-gauge by 4.76-cm intravenous catheter (Alliance Medical, Russellville, MO). Both thermocouples were connected to a portable temperature data acquisition device (Datalogger MMS 3000-T6V4; Commtest Instruments Ltd, Christchurch, New Zealand). The data from this device were electronically transferred to a desktop computer for statistical analysis.

Yet, unlike corporate servers that handle groupware applications or websites, the vulnerable server software - from process-control application maker LiveData - monitors and controls real-time devices in electric power utilities and healthcare settings. The best known types of devices are supervisory control and data acquisition (SCADA) devices and distributed control system (DCS) devices.

The complexity of the data acquisition system requires caution with respect to the synchronization of the data. If the computer in the Fast Track 8800 cannot acquire and process data fast enough to prevent buffer overruns, data from the various channels will not be properly synchronized in time. The results of this problem can be seen as excessive variability in the plots of modulus versus loading cycles
