What is the difference between pressure sensor and pressure transmitter, what's the difference between:

Pressure sensors are usually points to is a standard video signal output component level product, is the core of the pressure transmitting element, due to the non standard signal, users need and design pressure calibration when using a special signal processing circuit; Because the signal is weak, longer distance will need to add amplifier;

Pressure transmitter on the meaning of written also belong to the pressure sensor, but the output signals for the standard generic, such as 4 ~ 20 ma, 1 ~ 5 v, 0, 0 to 10 v to 5 v, etc., can be transmitted over a long distance, and with the standard instrument has been set at the same time the pressure value calibration, user needs range set by the instrument can be used.

The difference between the transmitter and sensor:

Sensor consists of two parts, namely, respectively is sensitive components and conversion components. The sensitive element refers to the sensor can feel directly or response was measured parts; Conversion element refers to the sensor will be sensitive element in feeling or response measured electrical part of the convert is suitable for transfer or measurement. As a result of the sensor output signal is generally weak, needs to be modulated with enlarged. With the development of the integrated technology, the circuit and power circuit is installed inside the sensor together. In this way, the sensor output can be easy to handle, the transmission of the available signal.

Many different kinds of transducer, transmitter is mainly used in industrial control instrument above: temperature transmitter, pressure transmitter, flow transmitter, current transducer, voltage transducer, and so on.
