BSH bellows sensor has good long-term stability
Date: 2025-12-05Read: 18
BSH bellows sensor is a pressure sensor that utilizes a bellows structure. A bellows is an elastic element, typically made of metal or synthetic materials, with a wavy structure. In sensors, bellows are used to sense changes in external pressure and convert pressure signals into measurable electrical signals through elastic deformation. The working principle is based on the response of the bellows to changes in external pressure. As the core component of sensors, bellows can undergo elastic deformation under pressure. When external pressure is applied to the inner surface of the bellows, the bellows will compress or expand according to the magnitude of the pressure. The sensing elements inside the sensor (such as potentiometers, capacitors, or resistors) sense the deformation of the bellows and convert this change into an electrical signal, thereby achieving pressure measurement.
BSH bellows sensorPart of the composition:
1. Bellows: As a pressure sensing element, the material and shape of the bellows determine its elastic properties. Common corrugated pipe materials include stainless steel, aluminum alloy, and synthetic materials.
2. Sensing element: an element that converts the mechanical deformation of a corrugated tube into an electrical signal. Common sensing elements include potentiometers, capacitive sensors, strain gauges, etc.
3. Shell: protects the internal components of the sensor and provides necessary structural support, usually made of metal or plastic materials.
4. Signal processing circuit: amplifies, processes, and outputs signals from sensing elements to obtain electrical signals proportional to pressure.
The main features of BSH bellows sensor are:
1. High precision and sensitivity
By adopting a precise corrugated tube structure and highly sensitive sensing elements, significant output changes can be generated under small pressure changes, with high measurement accuracy and sensitivity. This makes bellows sensors perform well in many applications that require high-precision pressure measurement.
2. Good anti-interference ability
Due to the structural characteristics of the bellows sensor, it can effectively isolate external electromagnetic interference and mechanical vibration, ensuring the stability and accuracy of the measurement signal. This enables the bellows sensor to operate reliably in complex industrial environments.
3. Wide range and high adaptability
Products can be designed to adapt to different pressure ranges according to requirements, with a wide range of working pressures. Accurate measurements can be provided from extremely low pressure to ultra-high pressure. It can adapt to special environments such as temperature, humidity, and corrosive gases, and is widely used for pressure measurement under various harsh conditions.
4. Long term stability
The design of the bellows sensor enables it to have good long-term stability, and even after long-term use, the elasticity and sensing performance of the bellows can maintain a high level. This makes bellows sensors an ideal choice for long-term operation, especially in applications that require continuous monitoring.
5. Compact and reliable design
Compact structure, small size, easy to install and use in environments with limited space. Its sturdy casing can effectively protect internal components from external physical impacts and corrosion, ensuring the reliability of the sensor in harsh environments.
