If you are talking about the little rod that melts causing the sprinkler to spray water, it is not an element. It is either a metal alloy or plastic that melts at a relatively low temperature. The older sprinklers all used metal alloy, but as the usual alloy contained lead as one of the metals that alloy has been phased out due to concern over toxicity. Where metal alloy is still used it has been reformulated without lead. But the preference now is to use plastic rods.
The image above shows a sprinkler with red colored plastic rod.
Automatic sprinklers often have a fusible (it melts) trigger made of Wood's metal. The metal is an alloy made of bismuth, lead, tin, and cadmium and melts around 160 F. The trigger holds the water valve closed and once it melts, the valve opens to release the water.
A typical sparkler is a combination of a reactive element wrapped around a metal wire. The elements commonly used are beryllium, magnesium or aluminum powders.

No, sprinklers in a deluge system are "open"; no valve in the sprinkler, and an automatic valve turns on the water to all open sprinklers when a fire condition is detected.
Rainbird is the most popular brand of sprinklers.
Water is used in sinks, showers, baths, hoses, sprinklers, fountains, toilets, etc.
Irrigation sprinklers are the most common on farms.
You take estimated overhead divided by the estimated level of production activity. It is used to assign overhead to production.
Sprinklers in a factory remove heat from the fire triangle.
Grocery stores have sprinklers only above the produce section because, when it is time to, the sprinklers automatically turn on according to how dry and products are. Hoped this helped! :)
A pergola is a overhead structure used to make the outdoors more inviting, to extend livable space, to create a shady retreat, and serve as a major landscaping element.
The predetermined overhead rate used to apply overhead to finished jobs is determined before the period begins.
No, most of them are have multiple settings allowing you to use on any type of plants.
