Because of this dependence on the excitation level, regulated power supplies are suggested for use with millivolt transducers. Because the output signal is so low, the transducer should not be located in an electrically noisy environment.
The distances between the transducer and the readout instrument should also be kept relatively short. Voltage output transducers include integral signal conditioning, which provide a much higher output than a millivolt transducer.
Although model specific, the output of the transducer is not normally a direct function of excitation. This means unregulated power supplies are often sufficient, as long as they fall within a specified power range. Because they have a higher level output these transducers are not as susceptible to electrical noise as millivolt transducers, and can therefore be used in much more industrial environments.
Since a mA signal is least affected by electrical noise and resistance in the signal wires, these transducers are best used when the signal must be transmitted long distances.
It is not uncommon to use these transducers in applications where the lead wire must be feet or more. Each pressure transducer has different aspects, that will impact how it works and the applications the pressure transducer works best for. The biggest differentiator is whether you can use a standard, off-the-shelf pressure transducer or if you need a custom pressure transducer.
For an off-the shelf pressure transducer, pressure transducer prices will be most affected, by the level of accuracy required for your application. Sino-Inst offers over 20 Pressure sensors. A wide variety of Pressure sensors options are available to you.

What is a pressure transmitter? SI High Pressure Sensor. Digital Pressure Transducer: A digital signal provides more versatility than analog signals, often they are called smart devices, because they provide greater functionality then other sensor types. Smart sensors can often describe their location, calibration information, log data, detect unusual events, or activate alarms.
Depending on the protocol the transmission distances can be more than a mile. Best use: Long transmission distances, smart sensing. Millivolt Output Pressure sensor ratiometric : The actual output is directly proportional to the pressure transducer input power or excitation. If the excitation fluctuates, the output will also change. Because of its dependence on the excitation level, regulated power supplies are suggested for use with millivolt transducers.
The sensor should not be in an electrically noisy environment because the output signal is so low. Voltage Pressure tramsitter: In this type of pressure sensor, the output is normally dc or Vdc and provides a higher output than a millivolt transducer due to its integral signal condition. Although model specific, the output of the transducer is not normally a direct function of excitation.
This means unregulated power supplies are often enough as long as they fall within a specified power range. They have a higher-level output and are therefore not as susceptible to electrical noise as millivolt transducers. Check out our supply of pressure transmitters here.

Hydrostatic pressure transmitters — often called level transmitters because of their working principle and ability to measure level. Hydrostatic pressure transmitters work on the basis that the amount of pressure increases with depth. These devices are submersible and can be used for liquids and gases.
