Drahtloser Temperaturmessumformer YTA510

Der leistungsstarke Temperaturmessumformer YTA510 kann Signale von einem Thermoelement oder Widerstandsthermometer bzw. Ohm oder DC-Millivolt aufnehmen. Messumformer dieser Baureihe übermitteln nicht nur Prozessvariablen, sondern auch die Einstellparameter mithilfe von Funksignalen. Die Messumformer werden über interne Akkus gespeist. Da somit keine feste Verkabelung erforderlich ist, können Einsparungen im Hinblick auf die Installationskosten erzielt werden. Die Kommunikation basiert auf den Spezifikationen des ISA100.11a-Protokolls. Das Modell mit abnehmbarer Antenne kann in Verbindung mit einer Antenne mit hoher Reichweite*1 verwendet werden, sofern ein Verlängerungskabel genutzt wird. Ein langlebiger Akkusatz mit extrem geringem Stromverbrauch sorgt über Jahre hinweg für einen zuverlässigen Drahtlosbetrieb.

A battery room is used to storage batteries for emergency power management in the plant. Each substation has battery room and the storage batteries are lead-acid batteries which must be maintained within specified operating temperature limits. Temperature management is important to ensure a long service life of the batteries especially for the plant in desert climates.

Delayed Coker is a type of coker who's process consists of heating residual oil feed to its thermal cracking temperature in a furnace. The most important variable in industrial furnace control is temperature. Temperature is measured throughout the furnace in different zones and temperature effects the materials being manufactured and therefore must be precisely monitored to prevent deviations in quality of the final product.

Geothermal power plants create electricity from geothermal energy. These power plants are similar to other steam turbine station; however their heat source is that of the earth's core. The created steam is used to turn the turbine for the production of electricity. Technologies include Dry steam, Flash steam and Binary cycle power stations with Binary cycle being the most common geothermal plant in current production. In the process of geothermal power generation the facility needs to monitor various processes, as in this case steam line pressure sits in remote from control room's location.

Temperature plays a key role in storage of Molasses to maintain the chemical properties of molasses. When temperature rises over 40.5 degree C, destruction of structure in sugar occurs, which results in losing the feeding property of molasses. There is also a safety concern that a rise in temperature can lead to a rise in storage tank pressure leading to an explosion of the tank.

In recent years, more field wireless devices have been used in hazardous areas. Meanwhile, in plants that are usually recognized as hazardous areas, there are numerous metallic tanks and pipes that easily shield or reflect radio waves, as discussed later, thus resulting in a poor environment for wireless communication.

The innovation of wireless technology increases the use of wireless communication in the industry. The introduction of wireless communication to plants, however, requires strict features such as robustness, real-time responsiveness, and low power consumption. This has restricted the use of wireless communication to limited applications such as data logging and device status monitoring that does not require strict real-time responsiveness and data arrival reliability in communication.
