Product type
Differential pressure sensors are devices that measure the difference in pressure between two points. They typically consist of a sensing element that detects pressure changes and converts them into an electrical signal. These sensors are commonly made from materials such as silicon, stainless steel, or polymer, depending on the application and required durability. They are widely used in various industries to monitor and control processes where pressure differentials are critical.
| Measurement range | 0 to 100 psi to 0 to 5000 psi |
| Output signal | Analog (0-5V, 4-20mA) or digital (RS485, I2C) |
| Accuracy | Typically ±0.25% to ±1% of full scale |
| Operating temperature | -40°C to 85°C |
| Media compatibility | Gases and liquids, depending on diaphragm material |
| Power supply | 5V to 30V DC |
When selecting a differential pressure sensor, consider the measurement range and the type of output signal that is compatible with your system. It's important to specify the accuracy and operating temperature range required for your application. Additionally, consider the media compatibility to ensure the sensor can withstand the fluids or gases it will encounter. Certifications such as CE or UL may also be relevant depending on your industry requirements.
