The cost of the cable route quickly exceeds the extra cost of the wireless modules.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eThe measurement is temporary.\u003c\/strong\u003e Nobody builds a permanent installation for a load test, a tension test on guy lines or a two-week measurement campaign.

You need at least two components, usually three.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eThe transmitter module\u003c\/strong\u003e sits at the sensor, excites the measuring bridge, digitizes the signal and transmits it. It is battery-powered and available in weatherproof housings, and in a compact design also for integration into the sensor housing.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eThe receiver\u003c\/strong\u003e determines what happens to the value. The options are base stations for the PC, rugged handheld displays for use on site, and output modules that translate the wireless value back into a conventional signal: analog as 4…20 mA or 0…10 V, as a relay switch point, or via a serial interface into the control system. This lets you connect a wireless sensor to a PLC that does not need to know anything about wireless.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eThe software\u003c\/strong\u003e is used to configure, scale and calibrate the modules and to log data. An SDK is available for your own applications.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eSince all modules work in the same network, several transmitters can be assigned to one receiver, and one value can be output to several receivers at the same time – for example to a handheld for the operator and in parallel to an analog module for the plant.\u003c\/p\u003e\n\u003ch3 dir=\"ltr\"\u003eEstimating range realistically\u003c\/h3\u003e\n\u003cp dir=\"ltr\"\u003eRange figures apply to a clear line of sight. In practice, steel structures, concrete walls, shelving, full silos and moving machinery attenuate the signal in the 2.4 GHz band considerably, and a transmitter mounted directly on a large metal surface radiates much less well than one with some distance from it.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eSo plan with a reserve, mount the antennas as high as possible and in sight of each other, and use a repeater for longer distances or buildings with many corners. Also keep in mind that the 2.4 GHz band is shared with Wi-Fi; in environments with dense radio traffic, channel selection is a topic for commissioning.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe advantage of the band: its use requires no registration and no fees, and you do not need a frequency allocation.\u003c\/p\u003e\n\u003ch3 dir=\"ltr\"\u003eMeasuring rate and battery life\u003c\/h3\u003e\n\u003cp dir=\"ltr\"\u003eThis is the central trade-off and the point where projects fail if it is not clarified beforehand. The modules can deliver high transmission rates, up to the range of a thousand readings per second. But exactly this rate consumes bandwidth and battery capacity.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eFor silo monitoring that needs a value every few seconds, transmitter modules with a sleep function run for a very long time on one set of batteries. For a dynamic measurement at a high rate, expect hours to days and plan for battery changes or an external supply. So define the required rate before you choose, and no higher than necessary.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eTwo more points for dynamic applications: wireless introduces a latency that can be too large for control tasks, and several transmitters do not automatically measure in sync.
