Process detection apparatus |
摘要 |
A compact pressure differential/pressure detector is a process detection apparatus for measuring a pressure, a level, a pressure differential of a process fluid. The detector is constructed of a pressure sensing block having sensors for sensing a pressure and a pressure differential, a signal processing block for processing signals from the pressure sensing block, and a terminal board block for receiving power supply from outside and transmitting signals to outside. These blocks are arranged along the same axis. Furthermore, an indicator indicating a process state is also arranged along the same axis and received in a covering case. The case is firmly attached to the pressure sensing block. The process detection apparatus permits a compact design and offers an excellent maintainability.
