Differential pressure transmitter sensors are useful for observing the pressure in vapor, liquid and gas and some of the points in selecting these pressure transmitter sensors are given in the following content:

The first point to be considered is the difference between a transmitter and a differential sensor. Even though, the difference between these two is not clear in a number of cases, the transducer is different from the sensor to certain extent since it is provided with a circuit for communicating with a computer or control panel. Some years back, it was easier to distinguish between the transducer and the sensor since the former was larger in size as compared to the latter. However, in the current circumstances, changes in the technology and design have made the transmitters to be of smaller size.

With the introduction of amplified voltage output pressure transmitters, the differences between the differential pressure transmitter sensors and other types of transducers have been completely removed. These new entrants are offered with signal strengths that are strong enough in sending their outputs to a far ...
... away distance than the signal of the strain gauge output pressure transducer. However, they have lesser power as compared to the traditional transmitters. If a device has a current loop output, it can be identified as a pressure transducer.

When a person wishes to purchase a differential model, he will have to be aware of the minimum voltage needed. However, it should be remembered that there will be a decline in the voltage across the pressure transducer in the event of load resistance. The user will have to identify the drop of voltage all along the load resistance and should deduct the same from the voltage obtained from the power source. In contrast, it is also essential to ensure that the real voltage used across the transmitter, will not go beyond the utmost allowable value for preventing any damage to the device. Even a minimal over-voltage can make some parts of the transmitter to get overheated thereby reducing its performance.

So, when looking for differential model sensor, the purchaser should check the technical data of the manufacturer. When it comes to particular voltage, some manufacturers will indicate the voltage for the main circuit, while some will point out the required voltage across the pressure transducer itself. Therefore, selection of a good manufacture or dealer is highly essential for ensuring the best quality transmitters.
