供应火焰传感器

价 格: 面议
型号/规格:R2868
品牌/商标:Hamamatsu

R6828产品为Hamamatsu日本公司生产, R2868 is a UV TRON ultraviolet detector that makes use of the photoelectric effect of metal and the gas multiplication effect. It has a narrow spectral sensitivity of 185 to 260 nm, being completely insensitive to visible light. Unlike semiconductor detectors, it does not require optical visible-cut filters, thus making it easy to use. In spite of its small size, the R2868 has wide angular sensitivity (directivity) and can reliably and quickly detect weak ultraviolet radiations emitted from flame due to use of the metal plate cathode (eg. it can detect the flame of a cigarette lighter at a distance of more than 5 m.). The R2868 is well suited for use in flame detectors and fire alarms, and also in detection of invisible discharge phenomena such as corona discharge of high-voltage transmission lines.

供应微波探测传感器

信息内容:

HB100微波探测传感器应用Doppler Radar原理,发射一个低功率微波并接受物体反射过来的能量。一旦物体的运动被其探测到。发射频率就被反射回的微波频率所替代,替代的微波与发射的微波混合在一起,结果一个低频率的电压从传感器输出。微波探测传感器的特性: 1、 非接触式。 2、 周围环境:不受热、嗓音、湿度、气流、尘埃等影响,适合恶劣环境。 3、 抗干扰。 4、 安全。 5、 宽范围。探测范围超过15米。更宽的范围亦可能。 如下参数是在5VDC, CW 工作状态, 12KΩ负载, +25℃下测定。 参数 备注 最小值 典型值 值 单位 频率 1 10.520 10.525 10.530 GHz 辐射功率 1 12 15 20 dBm Spurious Emission @ 3m 1 25 μV/m Settling Time 3 6 μSec Received Signal Strength 2 100 250 μVp-p Noise 3 5 μVrms Supply Voltage 4.75 5.00 5.25 VDC Current Consumption 30 40 mA ...
