<p>PURPOSE:To output it as an intermediate value signal how much relative level the value of an input signal is to an operational range, to which a warning is outputted, by continuously setting a proportional output band to the operational range, to which the warning is outputted. CONSTITUTION:The proportional output band is set adjacently to the operational range, to which '1' is outputted, in advance by inputting a start point AL. In this proportional output band, the value of a present temperature inputted from a temperature sensor through an input circuit is identified according to levels Th1-Th3 and the respective values are outputted as the intermediate values of 25%, 50% and 75%. Besides the warning output of '1' and '0', the intermediate value output is obtained to express the relative level to the operational range of the inputted measured value and the obtained intermediate value is displayed by the number of display lamps to be turned on. Thus, the state change of a control object can be grasped concerning its tendency and trouble is canceled to visually compare the measured value on a display panel with a set value.</p> |
