DTR131微波流量探測器:
DTR131是一個利用多普勒效應(yīng)的非接觸式微波運動探測器。電子器件發(fā)射一個信號，該信號被運動的物料反射。當(dāng)物料運動時，返回信號的頻率或高或低于發(fā)射信號頻率。如果這兩個信號的頻率相同，則認(rèn)為物料沒有運動。
DTR131發(fā)射的微波的能量為0.15mw/cm（天線的角），該水平遠(yuǎn)遠(yuǎn)低于的安全指標(biāo)10mw/cm，DTR經(jīng)過FCC-15F認(rèn)證。
DTR131能測量發(fā)射微波與反射微波之間頻率的不同。所能接收到的微波能量的改變（例如由于天線前有堆積物料）對有料流/無料流探測沒有影響。

DTR131 is a contactless microwave motion detector using doppler effect. The electronic device emits a signal which is reflected by moving material. When the material moves, the frequency of the return signal is either high or lower than that of the transmitted signal. If the frequency of the two signals is the same, it is considered that the material does not move. DTR131 the energy of the emitted microwave is 0.15 mw/cm( the angle of the antenna), which is far below the internationally recognized safety indicator 10 mw/cm,DTR certified by FCC-15F. DTR131 can measure the frequency difference between the emitted microwave and the reflected microwave. the change in the microwave energy that can be received (e.g. due to the accumulation of material in front of the antenna) has no effect on the material flow/no material flow detection.
