A pressure transducer is an important extruder spare part that is required in the plastic or vertical industry. Today many businesses which require pressure transducers are confused about which companies pressure transducers we should buy.
Before knowing
which one to buy, first, let’s understand what a pressure transducer is and in
what different types of it are available. Once this is clear you can easily buy
the required pressure transducer according to your industry needs.
Frequently Asked Questions
What is a Pressure Transducer?
A pressure
transducer is an electronic device that converts an applied pressure into a
measurable electrical signal which is linear and proportional to the applied
pressure. It consists of two main parts: an elastic material that will deform
when exposed to a pressurized medium and an electrical device that detects the
deformation and converts it into a usable electrical signal.
Types of Pressure Transducer
Resistive Pressure Transducer
(Strain Gauge)
A resistive
pressure transducer has strain gauges bonded to the surface of the non-media
contacted side of the diaphragm so that any change in pressure will cause a
momentary deformation of the elastic material resulting in a change of the
resistance of the strain gauge.
Capacitance Pressure Transducer
A variable
capacitance pressure transducer has a capacitive plate and another capacitive
plate fixed to an unpressurized surface gapped a certain distance from the
diaphragm. A change in pressure will widen or narrow the gap between the two
plates which varies the capacitance.
Inductive Pressure Transducer
An inductive
pressure transducer uses the principle of inductance to convert the flexing of
a diaphragm into the linear movement of a ferromagnetic core. The movement of
the core is used to vary the induced current generated by an AC-powered primary
coil on another secondary pick-up coil.
This was a quick
summary of the pressure transducer. Now you can buy the required pressure
transducer either online or from the shop. Now coming back to the question of
which company pressure transducer you should buy? the answer is Gefran
pressure transducer. The Gefran pressure transducer is
the most trusted device in the plastic industry by the majority of
customers.
If you are
looking to buy a Gefran
pressure controller, you can find it on Extruder
Supplies. Extruder Supplies is one of the leading spare part suppliers in the
USA.
