principle of measurement
using a specially designed sound meter resonator (saw), when there is a fixed frequency wave input to the sound meter resonator, the frequency of the resonator output wave signal will change with the resonator felt by the ambient temperature changes, using this characteristic, by collecting the output frequency of the resonator, you can convert the corresponding ambient temperature of the resonator, achieve the purpose of measuring the ambient temperature. the acoustic meter resonator has the advantages of passive, monotonic, good repeatability and good linearity.
main characteristics
dual 32-bit computer system, system redundancy; the temperature acquisition function uses 32-bit dsp processor, the program runs in the chip, fast speed, high reliability;
the temperature sensor adopts double chip design, which can effectively enhance the signal, ensure the stability of the signal, and solve the "multi-path effect" caused by the slight deformation of the cabinet in extreme cases;
using modbus communication protocol, it can communicate with the background to realize the functions of temperature online monitoring, temperature alarm and timing.
wireless temperature data acquisition, temperature measurement up to 160℃, good safety, large range, high precision;
saw temperature sensor small size convenient and flexible installation is not affected by the structure and space of the switch cabinet;
saw the temperature sensor works in passive mode. after successful installation, no maintenance is required. can work in strong magnetic, strong electricity, dust and other bad application occasions.
note: multipath effect means that after electromagnetic wave propagates through different paths, each echo component arrives at the receiving end at different times and superimposes each other according to their respective phases, causing interference and distorting the original signal or causing errors.
