Information retrieval through the Web is a multifaceted process and many side elements may affect on this procedure, for example searching the keyword process control. Nevertheless, our current knowledge about the complexity of this course of actions is limited. In spite of all remarkable progress in developing more sophisticated information retrieval tools on the Web, people may still encounter many difficulties for locating information they need for meeting their information needs. Although developing web-based search tools has been inspired by pre-web online information retrieval systems, a couple of unique features of the Web environment and the wide range of Web users’ characteristics impose new condition for searching and retrieval situation
The pressure or temperature to be controlled is applied to a sensor (manometric, tube, bellows, bulb). Whenever there is a change of pressure or temperature, the sensor is distorted and acts on a force balance connected to a microswitch. Opposite this sensitive element, an adjustable spring enables the working point to be adjusted : whenever the pressure on the sensor is sufficient to counter the spring pressure, the force balance changes position. Adding a second adjustable spring permits greater or lesser increase of the hysteresis (dead-band) or to act on dislocation between the two contacts if the instruments is thus equipped.
