In many devices, standard industrial sensors are used as sensors. Which are convenient, e.g. 0-24V. But they are not really cheap, and often a bit large.
Then it quickly pays to replace them with an electronic sensor on a PCB. To clarify a few examples:
A termo-coupler temperature measurement
In order to read out a termo-coupler, special electronics are required. This is available for e.g. PLC’s as an interface of e.g. € 40 - 80 per input.
If a circuit board is designed anyway, this electronics can be added for about € 15.
If you need 3 of them, this will already save € 200.
A force measurement bridge (Loadcell)
Force or weight measurement is often done with a strain gauge bridge. For this purpose, a measuring amplifier is used to create a 0 - 10V signal.
Again, if a circuit board is designed anyway, the measuring amplifier can be integrated for about € 15.
Special firmware can also provide a high signal-to-noise ratio.
A favourable result can also be achieved on the output side.
When the output currents are not too large (e.g. below 10A), relays in PCB version are also available. This saves wiring and assembly time from the PCB to an external relay and increases reliability. Savings per output are often between € 10 and € 20.
Solid State relays can also be included on the PCB, creating new possibilities, such as soft-start for motors.
When controlling control valves, an integrated electronic solution can be made cheap and robust, and also considerably cheaper than the standard interfaces.
When it comes to controlling small motors in particular, the differences are enormous. An integrated solution then costs about € 12 - 20,
compared to a standard solution of some € 100 - 150.
If you need e.g. 2, that already saves € 200.
Such an electronic design needs to be properly addressed in order to avoid parts having to be developed and tested more than once.` Therefore, depending on the production size, we spend a lot of time on analysis and optimisation.
Our specialty is at its best when you let us participate in thinking about your entire solution.
