SAW-based temperature sensing involves electrically inducing an acoustic wave into a piezoelectric mat erial and then reconverting the energy of the wave (influenced by the temperature to which the sensing element is exposed ) back into an electrical signal for temperature me asurement. One significant advantage of SAW device s is their passive operation, which makes them very amenable to operat ion in harsh environments via wireless interrogatio n. Passive, wireless, SAW-based sensing systems ha ve been described in many publications and some systems are now being of fered. Some of the available systems utilize SAW re sonators and some are SAW delay line based. The in terrogation techniques sometimes can include coding schemes Pos sibly the simplest and lowest cost techniques use u ncoded resonators at multiple frequencies. This li mits the number of unique identifiers available, but this can prove su fficient for certain applications, a few of which a re discussed in this paper. With any wireless syst em design, the ambient RF noise environment must be understood and addressed. Each application area presents challenges requiring engi neering support for mounting structures and methods , packaging, antenna design, etc., along with local regulations (e.g. FC C, CE, or UL) regarding emissions and safety requir ements in hazardous environments. In the systems de scribed herein, enclosures surrounding the SAW sensors may be well-shielded, a llowing resonator frequencies that are outside of r egulated frequency bands. The SenGenuity system op erates from approximately 428 MHz to 439 MHz. In these types of applications, SAW-based passive w ireless temperature sensing technology offers disti nct advantages over these traditional measurement m ethods, including • Passive operation, since SAW-based temperature sens ors require no batteries or external power-supply. The resulting advantages over actively powered sen sing solutions include: o Low environmental foot print as passive SAW tempera ture sensors avoid the adverse environmental impact of batteries. o Logistical advantage: The burden of regularly needi ng to monitor remaining battery life and replace th em is eliminated. • Electrically non-invasive solution: by not requirin g wires to power/read sensors, a SAW-based temperat ure measurement solution can provide an electricall y non-invasive solution for high power equipment such as switchgea r and other Smart Grid applications. • Wireless interrogation: SAW-based temperature senso rs can be read wirelessly. This makes them well su ited for rotating applications and for those applic ations where sensors are placed in difficult to reach or isolate d locations. The SenGenuity wireless SAW resonator (SAWR) based temperature sensing solution consists of a reader ( RF Transceiver) RF or capacitively linked to one or more SAWR sensing elements as depicted in Figure 1. The syst em operates in a range from 428 MHz to 439 MHz. Operational Description (Wireless Temperature SAW Sensor) Figure 1: Wireless SAW Temperature Sensing System Wireless sensors based on changes in resonant frequ ency require an appropriate reader. TempTrackr reader is base on “time domain” approach which is typical ly employs double heterodyne down-conversion with in-phase and quadra ture sample streams at base-band. Direct down-conv ersion and single heterodyne conversion are possibl e although the susceptibility to possible out-of-band spurious sig nals is worse. Discrete Fourier Transform (DFT) an alysis of the in-phase and quadrature samples to ob tain power spectral density (PSD) and curve fit interpolation of the PSD values are employed. While these extra steps incur addit ional electronics complexity and computational burd en, they overcome the limitations of the purely “frequency domain” method . The spacing of the interrogation frequencies is primarily limited by the bandwidth of the resonator response of the sensor and the bandwidth of the pulse’s power spectral density . Saturation of the receiver is desired in the tim e domain samples since frequency information is not lost through saturation. The effects of saturation in frequency domain and time domain readers is analogous to the same effect in a mplitude modulated (AM) versus frequency modulated (FM) radio receivers. In the time domain, saturation tends to make the ri ng-down of the resonator appear longer and more uni form, resulting in better apparent accuracy, as see n in Figure 3. The degree of saturation should still be somewhat limit ed to prevent deterioration of the spurious signal rejection ratio. 0 2 4 6 8 10 12 14 16 18 20 -1 -0.5 0 0.5 1 Time (microseconds) W ave A m plitude Figure 3. The decay envelope is shown for a resona tor with a Q of 10,000. The blue lines indicate th e received signal with no saturation. Red, purple and black indicate 2x, 5x, and 10x amplitude satura tion resulting in 2.5, 6, and 8.5 μ s of apparent increase in the decay time of the dig itized waveform. The Q of the SAW resonator is a critical parameter, both as the unloaded Q and as the loaded Q determi ned by the radiation resistance and loss resistance s of the antenna. Figure 4 illustrates that the resonator, with an unloaded Q of nearly 12,000, requires a loaded Q of at least 6,000 for high received signal strengths. A low-Q resonator of similar design is also shown with an unloaded Q of approximately 7,50 0. The diminished pulse width is seen to reduce th e received power by 3 dB. These values of Q are re adily achievable with SAW resonators. 2000 4000 6000 8000 10000 12000 -12-10 -8-6-4-2 02 Loaded Resonator Q Effective Relative Power of Received Response Figure 4.
