If you're working with equipment that generates oil, electricity, steam, nuclear power, chemicals or air, you'll likely need a pressure transmitter to regulate the pressure of these machines. Compressors, generators and other such machines should be equipped with pressure transmitters to meet safety regulations as well as to optimize your equipment's productivity.

When it comes to pressure transmitters, you can choose from several types, depending on your needs. You might require a differential pressure transmitter, a low pressure transmitter, an oil pressure transmitter or even nuclear pressure transmitters, or opt for a wireless pressure transmitter.

When you need a pressure transmitter, consider the following:

1. Choose brand-name pressure transmitters for reliability and performance.

2. Find pressure transmitter distributors who supply the type of transmitter you need.

3. Decide whether a wireless pressure transmitter will best suit your needs.

The best contacts and resources to help you get it done

Get the best names in pressure transmitter manufacturing

Most of us are comfortable with familiarity; we depend on brand names to deliver the best products to us. When it comes to pressure transmitters, you might feel more comfortable sticking with recognizable names such as Honeywell and Midas.

I recommend: Lesman Instrument Company has several Wika pressure transmitters to handle from zero to 1100 PSI. AC Controls Company offers both inline gauge and absolute pressure transmitters manufactured by Honeywell. JUMO Process Control has a Midas differential pressure transmitter designed to regulate the pressure of both gas and liquids.

Meet your particular needs with the right pressure transmitter

Pressure transmitters are not 'one size fits all.' Rather, the type of transmitter you require depends on your business's industry. Select the right distributor who offers exactly what you are looking for.

I recommend: For an easy to use pressure transmitter appropriate for many applications, check out AutomationDirect.com. Dwyer Instruments has a list of popular differential pressure transmitters for use in air, gas and liquid machines. Instrumart has a wide range of pressure transmitters at affordable prices.

Go wireless for ease of use, dependability and cost efficiency

You might prefer a pressure transmitter without the constraints of hard wiring. If so, look to a wireless pressure transmitter. These are efficient, reliable and can, in some instances, save money over hard-wired pressure transmitter installations.

I recommend: OMEGADYNE sells a wireless pressure transmitter for industrial use. ADALET Wireless manufactures several wireless pressure transmitters suited for most industrial applications.
