The pressure transmitter is an electronic instrument that converts pressure into an industry-standard electrical output. So the pressure transmitter is, as the name suggests, split into two parts; it measures the amount of liquid or gaseous pressure in a process, after which it transmits this data to a control system or screen. All this results in a safe, secure and monitored working space preventing downtime.
Pressure transmitters are flexible and suitable for various measurement tasks in a wide variety of applications. So are transmitters applied to detect the liquid level in vessels, determine the flow and pressure rate in pipes and monitor pumps. It can be said that pressure transmitters are like a true Swiss army knife; it’s never a bad call to use one.
Long story short, a pressure transducer is not a pressure transmitter. So when we speak of a pressure transducer vs transmitter, we speak of two different products. A pressure transducer is used before the pressure transmitter. A transducer converts a selected type of energy to another kind of energy. For example, the measured temperature of a liquid in your process is measured in Celcius and will be converted to analogue energy in the form of mV.
Pressure transmitters are used in a broad range of maritime and industrial sectors. In these branches, pressure sensors measure differences in value between the interior and exterior of pressure-sensitive equipment.
Depending on the type of transmitter and certifications, pressure transmitters are very durable and can withstand any environment with long service life. They significantly lower maintenance costs with testing periods of up to fifteen years rather than every two. Pressure transmitters are applicable in many cases because they can be connected to other systems, such as electrical circuits.
Also, pressure transmitters are widely used in the maritime sector. On board of vessels and cruise liners, everything revolves around liability and efficiency. In the marine industry, transmitters provide information about liquid or gaseous processes towards the engine room or bridge for monitoring.
