Can you distinguish between sensors, transducers, and transmitters, which are relatively similar products? They are often used interchangeably by different suppliers.
The term 'transducer' is widely used as a name for many devices and instruments. If you search online for sensors and transducers, or transducers and transmitters, you will get many different answers.
What is a sensor?
A sensor is a device that can detect and respond to physical phenomena, such as temperature, light, humidity, pressure, or other environmental conditions. Sensors can convert the physical effects of these phenomena into measurable electrical signals.
By doing so, a wide range of applications can monitor and control different processes, including medical diagnosis, weather forecasting, industrial automation, and many other processes.
What is a transducer?
A transducer is a device that can convert energy from one form to another. In sensors, transducers are typically used to convert physical signals (such as pressure, temperature, or light) into electrical signals that can be processed and analyzed. Sensors can be used for both measuring and driving systems.
In a measurement system, transducers convert physical phenomena into electrical signals that can be read and interpreted. In an actuation system, a transducer converts electrical signals into physical actions or movements that can be used to control or manipulate the system.
What is a transmitter?
A transmitter is a device that sends signals or information to another device or system. It is typically used in communication systems to transmit information through specific media such as air, wires, or fiber optic cables, such as radio signals, telephone calls, or data packets.
Transmitters typically convert information into electrical signals, which are then transmitted to the receiver through a transmission medium, where the signal is decoded and converted back into information.
The standard electrical signal is 1-5V or 4-20 mA, representing 0-100% of the measured physical variable. The transmission signal is detected by a receiver, such as an analog input on a PLC or DCS.
The difference between pressure sensors and transducers
Pressure sensors and transducers are interrelated, and in some cases, they can even be interchanged because pressure sensors typically include transducers. However, there are some fundamental differences between the two.
A pressure sensor is a device that measures pressure, typically using one or more sensors to convert pressure into electrical signals, such as voltage or current. The output signal of the sensor is then used to display pressure or activate other devices or systems in response to pressure.
A transducer is a device that can convert energy from one form to another. Sensors can be used for both measuring and driving systems.
In pressure sensors, converters are typically used to convert pressure into electrical signals, such as voltage or current output. Transducers can be integrated into sensors or can be separate components. For example, in a capacitive pressure sensor, the transducer converts pressure into a capacitive change, then measures the capacitive change and converts it into an electrical signal representing pressure.
Many suppliers can interchangeably use the terms pressure transmitter and pressure transmitter. But we now know that these two devices are not the same. So it is important to pay attention to their differences.
Pressure switch and pressure transmitter
There are significant differences in functionality and application scenarios between pressure switches and pressure transmitters.
A pressure switch is an electromechanical switch that monitors the pressure changes of a gas or liquid. When the pressure reaches a given threshold, it will automatically switch or trigger an alarm signal. This type of equipment is usually used to control the working status of pressure equipment, such as water pumps, fans, compressors, etc. Common application scenarios include industries such as water treatment, air conditioning, and automotive manufacturing.
A pressure transmitter is a device that converts pressure signals into electrical signals and outputs them to meet the needs of automated control and remote measurement. It can convert gas or liquid pressure into standard electrical signal output (such as 4-20mA, 0-5V, etc.) and transmit it to the process control system to achieve process control and monitoring. Common application scenarios include industries such as petrochemical, power, metallurgy, and mining.
