Master Pressure Sensors with JLCMC: The Ultimate Guide

Ready to master pressure sensors? JLCMC has provided you with a comprehensive guide covering the working principles and key applications of pressure sensors, taking you through the mysteries of pressure sensors.

What are Pressure Sensors?

Pressure sensors convert mechanical pressure from gases or liquids into electronic output signals. They primarily consist of sensing elements, signal conversion and conditioning circuits, output interfaces, housing and encapsulation, and power supply.

Pressure sensors have two important characteristics: (1) robustness to withstand high pressures; (2) elasticity to deform minimally and return to their original shape when pressurized.How Do Pressure Sensors Work?

How Do Pressure Sensors Work?

Pressure Sensing: The sensing element of pressure sensors directly contacts the measured medium to detect pressure changes. For example, in a Bourdon tube pressure sensor, the metal tube deforms in response to pressure variations.

Signal Conversion: Sensing elements translate pressure variations into electrical signals based on their materials and design. Taking strain gauge pressure sensors as an example, when the strain gauge deforms, its resistance changes, thereby altering its voltage or current.

Signal Conditioning: Signal conditioning is like cleaning up a messy radio signal. Pressure sensors make tiny electrical signals that need to be boosted, sorted out, and changed so they're clear and easy to read.

Signal Output: The conditioned signals from pressure sensors need to be transmitted through output interfaces, which can be either analog or digital, with the selection being influenced by factors such as cost, transmission distance, and the requirement for noise resistance.

Data Processing: Data Processing for pressure sensors cleans up the signals, like tidying up a cluttered room, and then saves and compares them with other info to give us the full picture.

What Are the Applications of Pressure Sensors?

Hydraulics: Pressure sensors are used to control force smoothly in hydraulic systems, managing large and sudden pressure jumps when control valves move rapidly. To ensure durability, only shock-resistant sensors should be selected.

Safety Control: Pressure sensors are essential for keeping things safe. They're ideal for looking after air compressors, small enough to fit anywhere, won't break the bank, and are a breeze to use.

Injection Moulds: In injection molding, pressure sensors are vital, installed in nozzles, runner systems, and mold cavities to measure plastic pressure throughout the injection, filling, packing, and cooling stages.
