Transducers
Transducers are a part of a measuring chain and they transform a physical quantity into an electrical signal. Transducers for gasTransducers are important for detecting physical quantities. Normally, such quantities as temperature, pressure, air humidity, sound pressure or light, are transformed into normalized signals (i.e. 4 ... 20 mA). The advantages of the transformation are on one hand flexibility, because many meters support the normalized signal processing. On the other hand, measured quantities can be read at a long distance without any loss of information. When transducers are used, the evaluation unit should only receive the measurement range, so electrical quantities are calculated from electrical signals. Some transducers also offer galvanic separation between both the input and output signal. You will find transducers for different quantities among our range of products. If you have questions about the transducers, you can contact us: UK customers +44(0) 23 809 870 30 / US customers +1-410-387-7703. Our technicians and engineers will advise you on these and other transducers, as well as on the other products of our range (regulation and control, scales and balances.

Nowadays transducers are essential in both automation and control systems. Transducers are needed when physical quantities are used for a process control. The reason is that it is necessary to record a large number of quantities. In addition to the most common quantities as temperature or pressure, there are other parameters such as pressure, gas content or flow. For electronics to receive a readable signal, transducers must convert the physical quantity into the electrical signal. To ensure flexibility, normalized signals can be read by many meters.

Here you can see the Transducers functioning:
Transducers: Function

The use of an analogue normalized signal allows transducersto be connected to the same analogue input of a digital display. The digital display should only be scaled, this means that digital display should indicate the value from transducers as an electrical quantity corresponding to a physical quantity value. The next image shows the assignment of 4-20mA output signal to a temperature range of  0 - 100 ºC:

Transducers: Graphics

Some transducers have a flexible scale which allows the users to adjust the measurement range according to their needs. Apart form its flexible use, the normalized signal of 4-20 mA has other advantages such as: connection cables from one device to another can be very long, it is possible to add diverse units of analysis to the same circuit, so a current signal from the transducer can be used in different places. As even with the lowest measurement value current flows, users can use the 4 mA to feed sensors. Current below 4mA indicates that there is something wrong with the analysis units. In order to read the measurement value in situ, some transducers have a display. Other transducer models have relays which make a contact when limit values are exceeded.
