What is the difference between a pressure transmitter and a pressure transducer?
Answer: A pressure transducer is a device that converts energy from one form to another.  It takes a physical property such as pressure or temperature and converts it into an electrical signal, such as 2mV/V. A pressure transmitter amplifies an electrical signal and converts it to a 4-20mA output.  Because a 4-20mA signal is minimally affected by electrical noise and resistance in the signal wires, a 4-20 mA output signal is best where the signal must be transmitted long distances.  It is therefore common to use a pressure transmitter for applications where the signal wire runs for distances up to 10,000 feet.

What pressure range should I work in?
Answer: A gauge range of twice the working pressure is generally selected. The working pressure in all cases should be limited to 75% of the gauge range.
Where alternative pressure and pulsation are encountered, working pressure should be limited to 2/3 of the gauge range.

Can you switch between 4 …20 mA and 1…5 V? 
Answer: No, the output signal is defined in the order and cannot be changed. 

What do I need to know to select the right product?
Answer:The following are the basics for most products used in industrial environments: Application - Pressure range - Temperature range - Medium - Pressure Connection
