【摘要】 电子式差动定温火灾探测器是一种特殊用途的传感器。本文给出了选择探测器关键参数的准则及选择、计算各元件参数的可靠判据。利用这些判据对传感器进行设计,无需再进行检验,从而为这种传感器批量生产,降低成本提供可靠的理论依据。更多还原

【Abstract】 The electronic difference/constant temperature fire alarm is a special function sensor with simple constructure. cheaper, high accuracy, selecting the sebsitivity according to the practical demand. This paper gives the strict principles for selecting key component parameters and the reliable criterion for selecting and calculating the component parameters. Moreovre, the given alarm demamds must be satisfied in designing and manufacturing the above sensor by making use of the above criterion. Therefore. the results here obtained provide the reliable theoretical basis for batch process and reducing production costs for the above sensor.更多还原
