How to Choose the Right Digital Pressure Gauge

A digital pressure gauge is an instrument used to measure the pressure of liquids and gases and then digitally display it. The transducer installed in the gauge converts the obtained pressure value into a digital reading.

Pressure gauges find extensive application in industrial and automaton industries. Their application is gaining traction in new areas of healthcare and energy production.

The display may be backlit and include various pressure related data collection and display functions, including data logging, min/max display, peak alarms, unit’s selection, tare function and more.

Pressure gauge manufacturers are incorporating new and advanced technologies to gain a market edge. With the market brimming with a variety of pressure gauges, selecting any one gauge is very difficult.

When the gauge is to be used in a hazardous environment, intrinsically safe certifications are available.

We are laying out a list of steps that can help you in selecting the best digital pressure gauge:

1. Check the Accuracy of Pressure Gauges

One major difference between mechanical and digital pressure gauges is accuracy. The accuracy provided by the latter is considered to be higher. Accuracy class from 0.5% to 0.05% of full scale.

Generally, the price of the gauge increases with accuracy. You must precisely evaluate the requirements of your applications before finalizing any particular instrument.

2. Decide Upon the Durability

Digital gauges are known to be very durable as they lack moving parts. They come in different types suitable for different applications.

For instance, some gauges are required to be moved around for use in applications such as testing and demand more robustness whereas some applications require stationary gauges.

Decide the kind of durability you need. This may turn out to be a cost-effective way as a durable pressure gauge will save the recurring cost of replacing it.

3. Give Preference to Readability

Readability is one of the primary reasons owing to which the digital pressure gauges are gaining preference over mechanical types. Besides the digital display, these digital gauges come with a backlight to facilitate effortless reading in a dark environment and an easy-to-read presentation.

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 Different

What is Thermocouple and How Does it Work? What is Thermocouple? The thermocouple is a kind of temperature sensor that is made by joining two different types of metals at one end. The heat is applied to the junction of the metals after which a voltage develops across the metals which is in correlation with the temperature. One end of the thermocouple is connected to the measuring junction, the body whose temperature is to be measured. The other junction is connected to the reference junction, the body with an unknown temperature. The thermocouple takes reference from the measuring junction to measure the temperature of the unknown body. The robustness and cost-effectiveness of thermocouples make them applicable across a wide range of temperature measurements. A thermocouple is available in many shapes and forms. Some of the commonly used styles are thermocouple probes, bare wire thermocouple, and infrared thermocouple. Determining the right kind of

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. Types of Pressure Transmitters 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 transm
