数字式就地指示压力表的设计

Design of digital indicating manometer on spot

采用扩散硅压力传感器、微功耗A/D、微功耗LCD显示器、微功耗MCU及数字校准等技术,设计了新型就地指示压力表。设计采用了A/D基准自动补偿及温度补偿技术,仪表具有显示清晰直观、耐振动、精度高及寿命长等优点。

Adopted diffused silicon pressure sensor,micro-power-consumption A/D,micro-power-consumption LCD,micro-power-consumption MCU and numeric adjustment technology etc,a new type indicating manometer on the spot has been designed successfully.The design uses A/D benchmark automation compensation and temperature compensation technology.It has many merits such as clearness,directness,vibration resistance,high precision and long life etc.
