Things to Check before Buying a New Pressure Transmitter

 Pressure transmitters are used in a wide variety of industrial applications to measure the pressure inside the machinery. These devices are considered critical products due to the following reasons:

Pressure transmitters serve as warning systems about impending disasters due to high-pressure levels.

These devices ensure that machines apply exact pressure levels during operation.

These Dongjin transmitters are also combined with other devices to measure altitude, depth, water flow, or loss of pressure, to prevent leaks in the system.

This means selecting a proper pressure transmitter is very important. An incorrectly chosen transmitter will affect the equipment, and increase the risk of danger. This post discusses all important factors that you need to consider before buying a pressure transmitter.

Factors to Consider When Purchasing a New Pressure Transmitter

The following are primary areas to focus on when buying a new pressure transmitter for your machinery.



Operating Conditions: Basic understanding of operating conditions will help in making the right selection. Wetted materials and transmitter cases can be chosen appropriately to extend the service life of the pressure transmitter. For example, all winter pressure transmitters for outdoor use have standard stainless steel housings for prevention against dust, and water.

Pressure and Temperature Ranges: Extreme temperatures can adversely affect the working of a transmitter. Hence, you need to consider the maximum, and minimum values the transmitter will experience. Consider the following values:

Normal operating pressure range – high and low

Maximum safe overpressure range (without bursting)

Frequency, and peaks of pressure pulses

Medium Measured: The measuring medium is another prime factor of consideration in pressure transmitter for sale selection. Ensure that parts of the transmitter exposed to the medium can withstand its particular characteristics.

Apart from the above-mentioned important considerations, you need to pay attention to the following:

Type of process connection required at the manifold valve and transmitter side

Housing material and electric connection/cable entry

Transmitter output

Type of Display – LCD or without display

Hazardous area certifications

The above-mentioned points will help ensure that you select the right pressure transmitter for your application. Also, you need to ensure that you are sourcing your transmitters from a reputed transmitter supplier in your area. You can do some online research to find them, individually check their websites, see their product catalogue, and check on forums before making a decision.

How UHMWPE Sheets Revolutionize Industrial Applications

图片
  Ultra-High Molecular Weight Polyethylene (UHMWPE) sheets are increasingly becoming a cornerstone in various industrial applications due to their exceptional properties. This material, renowned for its superior strength, durability, and versatility, has revolutionized numerous sectors, from manufacturing to medical fields. This article delves into how UHMWPE sheets are transforming industries and why they are favored over traditional materials.   1. Understanding UHMWPE Sheets UHMWPE is a subset of the thermoplastic polyethylene, characterized by its extremely long molecular chains. These chains, with molecular weights in the range of 3 to 6 million amu, contribute to its outstanding physical properties. UHMWPE sheets exhibit high impact resistance, low friction, and excellent chemical resistance, making them ideal for demanding environments.   2. Enhanced Durability and Wear Resistance One of the standout features of UHMWPE sheets is their unparalleled wear resistance. Industries tha

  To determine which camping chair is best for you, you will have to sift through material types, portability, price and many more. Therefore, we have put together a handy camping chair guide to make the choice a little easier. We go over the portability, weight capacity, materials and price of   camping chairs   to help you decide. HERE'S WHAT YOU SHOULD LOOK FOR WHEN YOU'RE BUYING A NEW CAMPING CHAIR.   1. Materials   First, let's take a look at the materials used in making one camping chair. There is a vast variety of camping chair materials that you can choose from when shopping for a camping chair. But, most current models have aluminum legs and body frame. This is because aluminum has a high strength-to-weight ratio. Plus, aluminum is corrosion resistant so it prevents rust.   As for the seats and armrests, a coated rip-stop nylon fabric is used because of its durability and water resistance capabilities. But some brands use closed-cell foam padding instead for extra

Is Sublimation Paper the Same as Heat Transfer Paper?

图片
In the realm of garment printing and crafting, confusion often arises between sublimation paper and   heat transfer paper . While both are vital tools in the process of transferring designs onto various surfaces, they serve distinct purposes and possess unique characteristics. Understanding the disparities between these two types of paper is crucial for achieving optimal results in your printing endeavors. Sublimation Paper: Unveiling its Essence Sublimation paper  is a specialized medium used primarily in sublimation printing—a technique that involves transferring dye onto materials such as fabrics, ceramics, and metals through a process of sublimation. Sublimation occurs when a solid substance transitions directly into a gas without passing through the liquid phase. In sublimation printing, heat and pressure are applied to sublimation paper, causing the solid dye particles to sublimate and bond with the surface of the substrate. The key characteristic of sublimation paper is its uniq
