What Is Hastelloy?
Never heard of Hastelloy? Well, it is the trademark name of Haynes International, Inc, for a series of high-strength, nickel based, corrosion resistant alloys. Hastelloys are commonly used by the chemical processing industries and have many applications. The Hastelloy trademark is applied as the prefix name to about twenty two different metal alloys loosely grouped by the metallurgical ...
How Much Do You Know About Lathes?
Generally a lathe is a machine tool which spins a block of material to perform various operations such as cutting, sanding, knurling, drilling or deformation with tools that are applied to the workpiece. An object is created that has symmetry with an axis of rotation. Today we have CNC lathes that are rapidly replacing older ...
Pressure Transducers
If the nature of your work relies on different types of vehicles, like underwater applications, aerospace vehicles, machines to work with gas and oil or for other industrial purposes, you should know which parts will make those applications more productive and long-lasting. I've recently been blogging about pressure transducer types and different applications, so ...
Pressure Sensors: Specific Features
A pressure sensor measures the pressure, generally gas or liquid pressure. Pressure is the expression of the force which may be required to stop a fluid from expanding. A pressure sensor detects a signal coming from an imposed pressure. The signal is typically electrical, but it may also be optical, visual and auditory. Pressure sensors are ...
Types Of Pressure Sensors
There are different types of pressure sensors. They are classified in terms of temperature range of operation or the pressure ranges they measure. Therefore, the most important classification is made according to the type of pressure they measure. From this point of view, pressure sensors can be divided into five categories. First of all, let's consider absolute ...
Downhole Sensors
A Downhole sensor is a device which can measure various properties such as pressure, fluid flow rate from each branch of a multilateral well, vibrations, fluid flow regime, fluid holdup and composition. These devices can be permanent and left in one place for months, even for years. There are types of downhole sensors are specifically designed for ...
Differential Pressure Transducers
A differential pressure transducer measures the difference between two or more contacts. This is a more complicated task, as there are two or more sensing units to be considered. Let's examine different types of differential pressure transducers varying by their features and pressure ranges in the table below. Special Features Style Minimum Pressure Range Maximum Pressure Range Accuracy ...
