过去的煤气泄漏检测器的传感器是直接接触泄漏气体来进行测量。因此,从产生气体泄漏到传感器周围气体浓度达到检出水平需要一定的时间,因而,从气体泄漏到报警将产生一定的时间滞后。虽然现在这个时间滞后还没有达到影响安全的程度,可是,今后随着煤气储罐等大型煤气设施的普及,希望尽量缩短这个滞后时间。超声波式煤气泄漏检测器,是利用煤气泄漏喷出时产生超声波的原理,来检测泄漏的,因此,滞后时间非常短。
The past gas leak detector sensor is in direct contact with the leak gas to be measured. Therefore, it takes a certain amount of time from the gas leakage to the gas concentration around the sensor to reach the detection level, and thus a certain time lag occurs from the gas leak to the alarm. Although this time lag has not yet reached the level of impact on safety, however, with the popularity of large-scale gas facilities such as gas storage tanks in the future, we hope to minimize this lag time. Ultrasonic gas leak detector, the use of gas leaks when the principle of ultrasonic waves generated to detect leaks, therefore, the lag time is very short.
