slide 2: Before we understand how to select the right
pressure switches
What is Pressure Switches
Pressure switches are an indispensable component that is found in every
industry. Even though it is a simple instrument the function of its services
is one of the most important healthy production factors which is also for
the safety of plants and machinery.
In today’s modern industrial era there are many technologies used in
making a pressure switch which provides different options for the user.
This is what makes it important that we select the correct instrument for our
application.
Let us look at some points to consider while selecting Hubbell Pressure
Switches:
slide 3: Inclusion – The need for housing used to make the switch makes sure
that proper material is being used for a correct switch is used in such
an environment conducive to good service life. The different materials
are available like die-cast aluminum stainless steel in various grades
like SS304 SS316 etc. Also polyester or other plastic-based
compounds.
Fireproof enclosures – Here Hubbell Pressure Switches use heavy
protective enclosure usually made of die-cast steel or aluminum. In
case of the heat or sparks from faulty equipment within the enclosure
ignite flammable gas present with it the resulting explosion is
contained.
Some of the suitable flameproof cable glands are able to ensure proper
protection and opening enclosure while powered is strictly not
allowed.
Sensor – When it comes to sense the mechanism used in the making
of a pressure switch is an important criterion that has to be considered
while selecting a pressure switch. Some of the sensors used in Hubbell
Pressure Switches are Bellow Diaphragm and Electronic.
slide 4: Dead band – The difference between the set and reset point of a
pressure switch is known as a dead band. The available dead bands
are: a fixed dead band narrow band adjustable wideband adjustable
and fully adjustable.
