自動機械的完全性検証
Document Type and Number:
Japanese Patent JP5301461
Kind Code:
B2
Abstract:
A process transmitter for measuring a process variable comprises a process sensor, transmitter circuitry, a transmitter housing, a mounting component, and a non-contact proximity sensor. The process sensor senses a process variable of a process fluid. The transmitter circuitry processes a signal from the process sensor. The transmitter housing receives the process sensor and transmitter circuitry. The transmitter mounting component is connected to the housing to isolate the sensor, the transmitter circuitry or the transmitter housing from the process fluid or an external environment. The non-contact proximity sensor system detects a spatial relationship between the transmitter housing and the transmitter mounting component.
