摘要： A diagnosing operation controlling portion compares the magnitude of change of a control instruction value that controls the dislocation of a valve stem to a reference value that has been set in advance, and stops the malfunction evaluation operation in a diagnosing portion if the magnitude of change per unit time in the control instruction value exceeds a reference value. If the magnitude of change per unit time in the control instruction value exceeds the reference value, then the evaluation may be the same as for a case wherein a stick-slip has occurred, even if the operation is functioning properly. In contrast, it is possible to prevent incorrect stick-slip evaluations by stopping the operation of the diagnosing portion when the magnitude of change per unit time in the control instruction value exceeds a reference value.

摘要： An image processing device includes an estimating portion and a controlling portion. The estimating portion estimates a frequency component of noise that is included in both the first and second images, and a frequency component of a first image that does not include the noise, based on first image data obtained through imaging, using an imaging device, a first image that includes a specific image pattern, and based on second image data obtained by imaging, using the imaging device, a second image that does not include the specific image pattern. The controlling portion controls weightings, relative to frequencies, when calculating a correlation between the first image data and third image data, obtained through imaging a third image through the imaging device, based on the individual frequency components estimated by the estimating portion.

摘要： A differential pressure transmitting device detects, through two pressure guiding tubes, a differential pressure that is generated when that which is to be measured, such as a liquid, a slurry, or a gas, that has fluctuation in the pressure thereof, passes through a differential pressure generating mechanism.

摘要： A vessel is attached to a pressure guiding tube near the point of connection between a process pipe and a pressure transmitter. Doing so increases the rate of deformation, relative to a change in pressure, of a fluid when the fluid is a compressible fluid, making the change in the pressure fluctuation more easily detected, thereby increasing the sensitivity of detection of blockages in the pressure guiding tube. If the fluid is a non-compressible fluid, then a part that has a diaphragm (a pressure bearing surface that deforms easily through pressure) is connected instead of the vessel.

摘要： For example, a regulator valve may be controlled from the outside through a positioner, or may be controlled autonomously by an adjusting mechanism in the valve. The result of the control is a change in the dislocation of the valve stem (movable portion). Additionally, there will be a change in a process change magnitude, such as the magnitude of flow of a fluid that passes through the regulator valve, in accordance with the magnitude of dislocation of the valve stem. In this way, the diagnosing operation controlling portion controls the operation of the diagnosing portion based on the magnitude of dislocation of the valve stem or on the magnitude of change of the measurement results (the measurement value) of a process change magnitude.
