If you are unfamiliar with the part numbers for pressure transmitters, here are some helpful tips. First, make sure you have an accurate application. If you're using an analog sensor, you'll need two different transmitters - one for the liquid application and another for the gas application. You should keep both in stock. Then, you can easily order replacements if they ever become damaged. You'll also be able to save money by not having to keep inventory for multiple models.
When ordering pressure transmitters, make sure you have a part number. This is an important feature because it allows you to ensure that you get the exact product you need. Some companies provide instructions for ordering part numbers, but they can also be confusing. Many manufacturers have several different part numbers for pressure transmitters. In the case of Deltabar, for example, the PMD75 differential pressure transmitter uses a piezoresistive sensor and welded metallic membrane. This model is popular with process measurement and safety applications.
Pressure transmitters vary in accuracy and reliability. High-quality models are able to handle up to 200 bar on one side. A low-cost version can measure pressures as low as 35 mbar. They often feature a sturdy mechanical design and a 4...20 mA output signal. This type of transducer is ideal for long-range operation. If you're worried about electrical noise, you should choose a pressure transmitter with a lead wire of more than a thousand feet.
Using pressure transducers is an excellent way to monitor and analyze pressure levels. These devices can measure up to 3 inches of water and 200,000 psig (1440 MPa). You can also use a strain gauge-type pressure transducer if you're measuring the pressure in a narrow area. This type of transducer is ideal for applications where differential and high-pressure measurements are needed.
Once you have determined which type of pressure transducer you'll need, you can then order the parts. When you have an idea of the size and configuration you need, you can then order a replacement part number. You can even order a custom pressure sensor to meet your specifications. And, of course, you can customize the unit to your exact specifications. So, when you're ordering, make sure you know the part number of the device you'll need.
In addition to knowing the part numbers, it's also important to know the type of pressure transmitter you need. You can order a standard pressure transducer by referencing a reference manual. You can also use the same part number for your custom pressure sensor. However, you may need to order a higher-quality transducer for extreme temperature environments. If you're buying a custom pressure transducer, you'll need to know the part number.
