Rotary Mounting Bracket for Stable Field Device Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing field devices such as fill level and pressure measuring devices face challenges in maintaining a precise measuring position due to vibrations and mechanical influences, leading to incorrect measurements when attached to inclined or uneven surfaces using traditional flange or screw-in attachment methods.
Innovation Solution
A mounting bracket with articulated rotary bearings and a lock mechanism allows field devices to be aligned and secured at any desired angle, preventing undesired rotation through the use of pivot points and screws, enabling precise positioning and secure attachment to variously inclined surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flange attachment or screw-in attachment is used, then the field device can be securely attached to the container, but the attachment position is fixed and inflexible
Solution Approach 1:
The mounting bracket incorporates a rotatable bracket strap with rotary bearing that allows the field device to be rotated to different angle positions (e.g., 0°, 45°, 90°, 135°) while maintaining secure attachment. This dynamic adjustment capability resolves the contradiction by enabling both secure attachment and position flexibility.
2Adaptability or versatility
If rotatable brackets are used to attach field devices to inclined surfaces, then attachment flexibility is improved, but the device cannot maintain its set position due to vibration and mechanical influences
Solution Approach 1:
The lock mechanism is designed to be movable along the bracket strap and can be positioned at different locations corresponding to different angle positions. By engaging the lock at the desired position before vibration occurs, the system preliminarily sets the correct position that will then be maintained against vibrational forces.
Solution Approach 2:
The lock acts as an intermediary element between the bracket strap and the field device, transmitting and maintaining the rotational position. It mediates between the rotational freedom provided by the rotary bearing and the positional stability required for accurate measurement.
3Adaptability or versatility
If the field device is attached to inclined surfaces or vibrating containers, then measurement adaptability is improved, but measurement precision deteriorates due to rotation-induced errors
Solution Approach 1:
The combination of rotary bearing and lock mechanism allows the system to dynamically adapt to different surface inclinations by rotating to the appropriate angle, then lock to maintain that angle precisely during operation, thereby preserving measurement precision while gaining adaptability.

AI summary
A mounting bracket is adapted for mounting a field device, as well as to a field device that for the purpose of attachment to a mounting surface comprises such a mounting bracket. The mounting bracket comprises (a) a first bracket strap which includes a first rotary bearing, (b) a second bracket strap, spaced apart from the first bracket strap by a space, including a second rotary bearing and (c) at least one movable lock on one of the two bracket straps. The rotary bearings are designed to articulate on two opposing sides a field device that may be arranged in the space so that the field device may be rotated, on an imaginary axis that extends through the space, from a first angle position to a second angle position. The lock is designed to engage the field device in order to in this way resist a torque of the field device in that said lock converts the torque to a pair of forces which is removable by way of one of the rotary bearings and by way of the lock itself.
