First of all, let’s discuss the terms Transducer and Transmitter. Some people will tell you that a Transducer and a Transmitter are the same things and therefore the terms are interchangeable. If you are curious, conduct a web search of the two terms and you will be surprised at the wide range of results! A transducer is a device that converts one form of energy to another. For example, an electrical transducer converts a sensed physical variable like temperature into an analog electrical signal. A transmitter is a device that converts the electrical signal from the transducer into a much larger electrical signal that can be sent over a long distance to a PLC or a DCS. The transmitter output signal is usually a range of voltage (1 to 5 V) or current (4 to 20 mA) which represents the 0 to 100% of the sensed physical variable. A Pressure Transmitter is an instrument connected to a Pressure Transducer. The output of a Pressure Transmitter is an analog electrical voltage or a current signal representing 0 to 100% of the pressure range sensed by the transducer. Pressure transmitters can measure absolute, gauge, or differential pressures. Absolute pressure is referenced to a perfect vacuum which is considered 0 psi! We express vacuum pressure as 0 psi (a). Atmospheric pressure is usually about 14.7 psi (a). The most common pressure measurement is gauge pressure which is the total pressure minus the atmospheric pressure. Atmospheric pressure is 0 psi (g). Let’s have a look at an example of a Pressure Transmitter measuring process pressure of gasses in a pipeline. ============================= You might want to review 2 of our other videos: 1) What is a Pressure Sensor? https://realpars.com/pressure-sensor/ 2) Differential Pressure Transmitter Explained https://realpars.com/differential-pressure-transmitter/ ============================= Missed our most recent videos?
