Abstract
Description
Technical Field
[0001] This utility model relates to the field of differential pressure transmitter technology, specifically an anti-interference differential pressure transmitter. Background Technology
[0002] A differential pressure transmitter is a transmitter that measures the pressure difference between its two ends and outputs a standard signal. Unlike ordinary pressure transmitters, differential pressure transmitters have two pressure ports. Differential pressure transmitters are generally divided into a positive pressure port and a negative pressure port. The pressure at the positive pressure port of the differential pressure transmitter must be greater than the pressure at the negative pressure port in order to measure the pressure.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-4This utility model provides a technical solution: an anti-interference differential pressure transmitter, including an anti-interference differential pressure transmitter body 1, a first support 2, and a mounting hole 3. The first support 2 has a mounting hole 3 on its upper part. The anti-interference differential pressure transmitter body 1 is responsible for measuring differential pressure and converting it into an electrical signal output. The anti-interference differential pressure transmitter body 1 is an ABB Type 1 transmitter. The 269F differential pressure transmitter is renowned for its high precision and anti-interference performance. The anti-interference differential pressure transmitter body 1 is threaded onto the first support 2 via bolts through the mounting hole 3, thus firmly fixing the anti-interference differential pressure transmitter body 1 onto the first support 2, ensuring the reliability and durability of the connection. The cross-sections of the first support 2 and the second support 7 are both U-shaped. The anti-interference differential pressure transmitter body 1 is vertically set on one side of the outer wall of the first support 2. A clamping plate 4 is set in the middle of the first support 2, and a first fixing wire 5 is set on the first support 2. The first fixing wire 5 fixes the first support 2 in a designated position, providing additional fixation and support to prevent displacement caused by external vibration or impact, effectively improving the anti-interference performance of the differential pressure transmitter. The clamping plate 4 is vertically set on one side of the first support 2, and an arc-shaped opening is set at one end of the clamping plate 4. The first fixing wire 5 is located below the clamping plate 4.
[0020] The bottom end of the first support 2 is rotatably connected to the second support 7 via a rotating shaft 6, allowing a certain degree of relative movement between the two supports. Two springs 8 are provided at the bottom end of the first support 2. One end of the spring 8 abuts against one side of the top surface of the second support 7, and the outer wall of the "U"-shaped extension end of the first support 2 abuts against the inner wall of the "U"-shaped extension end of the second support 7, maintaining the compactness of the structure. One end of each of the two extension ends of the first support 2 is provided with an inclined slot, and one end of each of the two springs 8 is connected to the slot, allowing the springs 8 to extend and retract along the direction of the slot, further accommodating the rotational adjustment of the first support 2 at one end of the second support 7. One end of the second support 7 is provided with a second fixing wire 9. Two through holes are provided on one side of the middle of the first support 2 and the end of the second support 7 away from the first support 2. The two ends of the first fixing wire 5 and the second fixing wire 9 are respectively threaded to the through holes provided in the first support 2 and the second support 7, facilitating position adjustment and disassembly.
[0021] First, the anti-interference differential pressure transmitter body 1 is bolted through the mounting hole 3 on the first support 2 and securely fixed to the first support 2 using a threaded connection, ensuring the stability and reliability of the anti-interference differential pressure transmitter body 1. One end of each of the two extension ends of the first support 2 has an inclined slot, and one end of a spring 8 is connected to these slots, allowing the spring 8 to extend and retract along the slot direction to accommodate the rotational adjustment of the first support 2 at one end of the second support 7. The first fixing wire 5 and the second fixing wire 9 work together to provide additional fixation and support, preventing displacement caused by external vibration or impact. Simultaneously, the inclined slot and threaded connection design allows for easy adjustment of the system to adapt to different installation environments and measurement requirements, improving the anti-interference capability of the differential pressure transmitter and enhancing its flexibility and reliability in practical use.
