Multi-channel pressure sensor controller |
摘要 |
In a multi-channel pressure sensor controller, measured pressure signals from a plurality of pressure sensors to each of which a channel number is assigned are subjected to selection at a multiplexer using a selection signal based on the output of an arithmetic and control unit; the measured pressure signal from the selected pressure sensor is converted by an A-D converter into a digital value; under the control of the arithmetic and control unit, a display unit shows an indication of the digital value converted by the A-D converter and the channel number assigned to the pressure sensor outputting the measured pressure signal having the digital value; a threshold stored in advance for the channel number is compared with the digital value obtained by performing Analog-Digital conversion on the measured pressure signal from the pressure sensor associated with the channel number; and an indication based on the output of the comparison is shown at an alarm indicator lamp for a channel number provided on an alarm unit under the control of the arithmetic and control unit.
