Mounting Bracket With Rotary Bearings And Lock For Field Devices
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 inflexibility in attachment methods, particularly when attached to inclined or vibrating surfaces, leading to incorrect measurements.
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 and ensuring a stable measuring position through the use of disc-like expansions and pivot points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional flange or screw-in attachment methods are used, then the field device can be attached to the container, but the attachment position is fixed and inflexible
Solution Approach 1:
The mounting bracket incorporates a rotatable connection that allows the field device to be dynamically adjusted to different angles and positions. The bracket can rotate relative to the container wall, enabling adaptation to various surface orientations while maintaining a relatively simple structural design through the use of a single rotational degree of freedom.
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 influence
Solution Approach 1:
The mounting bracket includes a locking mechanism that can be activated after the desired rotation angle is achieved. This preliminary positioning followed by locking ensures that the field device is first adjusted to the correct measuring angle, then securely fixed to maintain that position against vibrations and mechanical influences during operation.
3Ease of operation
If the field device is allowed to rotate freely on the mounting bracket, then positioning flexibility is improved, but rotation cannot be prevented by the mounting bracket
Solution Approach 1:
The mounting bracket provides dynamic positioning capability during installation, allowing easy rotation and adjustment of the field device to the desired angle. Once positioned, the locking mechanism transitions the system to a static, fixed state that prevents unwanted rotation, thus ensuring measurement reliability while maintaining operational ease during setup.

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 of 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 the 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.
