Pressure Transmitter – Types & Accuracy

 


What is a Pressure Transmitter?

Pressure transmitters, also known as pressure transducers, are used in industrial and process applications to measure the pressure of liquids, fluids, and gases in different working equipment. These transmitters are a vital component in process industries, especially the oil & gas industry which deals with a variety of fluids and gases.


They are commonly used to create a liquid interface detector to monitor the level of liquid in different connected pipelines of a system. Measurement and maintenance of the pressure level of different components in these industries are vital for their smooth functioning as any variation above or below the prescribed pressure can cause disasters. Pressure transmitters are often used in conjunction with other devices to ensure the proper functioning of any system. These transmitters are made very robust to withstand extreme environment which enhances their applicability in a range of industries. Pressure and Differential Pressure transmitters are primarily used in level measurement, flow measurement, and filtration system monitoring.


Pressure transmitters and sensors have become a vital component in the industrial sector owing to their wide range of applications. These transmitters are used to measure the pressure of a variety of fluid along with identifying any kind of leakage. Pressure transmitters are increasingly used in different types of research and development activities across different sectors such as the automotive and aircraft sectors. Here they are used to measure the pressure of fuel, water, air, and other manufactured products. The food and beverage sector has emerged as the new arena of application where the pressure transmitters are used in brewing and dairy applications to measure bottling points. New types of sensors are making way into the market. The pressure transmitters are also being used in many new fields and domains to satisfy new requirements.


Types of Pressure Transmitters

Pressure transmitters can be categorized into four main types:


1. Gauge Pressure Transmitter

As the name suggests they measure the gauge pressure with respect to the atmospheric pressure. These types of transmitters are widely used in process industries as they involve the use of liquid and gases. The need to keep their pressure under check makes gauge pressure transmitter a vital component of the industry.


2.  Absolute Transmitters

These transmitters are used to measure pressure with respect to full vacuum. Basically, the media under measurement is placed in a sealed chamber to create a reference to absolute vacuum. These absolute pressure transmitters are generally employed in areas which demand a very high level of accuracy.

What is Thermowell? Thermowell Types & Application

  A thermowell is a protection for the temperature sensors in the form of cylindrical shaped pressure-tight fittings. It is used to protect the temperature sensors which are inserted into vessels and pipes for being used in different industrial applications. It is used to create a barrier between the process media and sensing element as the process media can be corrosive and can negatively impact the sensing element. Moreover, it protects the sensing elements from fluid velocity and pressure. Thermowell Types: 1. Threaded Thermowell They are usually used in smaller pipes where the temperature of the non-corrosive fluid is measured. Threaded thermowell is screwed in the pipe for use and generally does not require replacements. 2. Flanges Weld Thermowell As the name suggests, flanged thermowell is flanged at the top end. It is connected to the pipe using nuts and bolts. It is mostly used in applications that require frequent replacements and involve high temperatures. 3. Socket Weld...
