The Eugene Science Center, located in Alton Baker Park in Eugene, Oregon, United States, is a science and technology center for children, families, and school groups.The 10,000-square-foot (930 m 2) museum near Autzen Stadium features changing interactive exhibits, planetarium shows, camp programs, special events and other science and technology-related education programs.
The simplest resistance-thermometer configuration uses two wires. It is only used when high accuracy is not required, as the resistance of the connecting wires is added to that of the sensor, leading to errors of measurement. This configuration allows use of 100 meters of cable. This applies equally to balanced bridge and fixed bridge system.
NTC thermistors are widely used as inrush-current limiters and temperature sensors, while PTC thermistors are used as self-resetting overcurrent protectors and self-regulating heating elements. An operational temperature range of a thermistor is dependent on the probe type and is typically between −100 and 300 °C (−148 and 572 °F).
The integrated circuit sensor may come in a variety of interfaces — analogue or digital; for digital, these could be Serial Peripheral Interface, SMBus/I 2 C or 1-Wire.. In OpenBSD, many of the I 2 C temperature sensors from the below list have been supported and are accessible through the generalised hardware sensors framework [3] since OpenBSD 3.9 (2006), [4] [5]: §6.1 which has also ...
A sailor checking the temperature of a ventilation system. Some typical circumstances are where the object to be measured is moving; where the object is surrounded by an electromagnetic field, as in induction heating; where the object is contained in a vacuum or another controlled atmosphere; or in applications where a fast response is required, the accurate surface temperature is desired or ...
Some advanced models have touch screens, or the ability to work with home automation or building automation systems. Digital thermostats use either a relay or a semiconductor device such as triac to act as a switch to control the HVAC unit. Units with relays will operate millivolt systems, but often make an audible "click" noise when switching ...
Figure 2: [8] Working principle of a thermal laser sensor (Adapted from figure 3 with permission) As shown in Fig 2, a thermopile laser sensor consists of several thermocouples connected in series with one junction type (hot junction at temperature T 1) being exposed to an absorption area and the other junction type (cold junction at temperature T 2) being exposed to a heat sink.
ThermoSensor is a coin-sized battery-powered RFID-enabled temperature sensor which is to be attached to the lower abdomen of patients by using 3M Tegaderm for body temperature monitoring. ThermoSensor was invented by the company Cadi Scientific in 2003 in Singapore for body temperature monitoring but it was later used for location tracking of ...
