ADS11 Series Piezoresistive Diffused Silicon Absolute Pressure Sensor Core For Industrial Automation

Uses:

• Industrial Automation: Widely used in pressure control scenarios in industrial automation, such as monitoring the pressure level in fluid systems or compressors. It can convert the analog signals from pressure sensors into digital signals, providing accurate pressure readings for micro - controllers to adjust pressure - regulating devices, ensuring the safety and efficiency of the entire system. It can also be used for temperature and flow control, cooperating with temperature sensors and flow sensors to achieve precise monitoring and control of temperature and flow.
• Robot Technology: In robot systems, it is used to measure various pressure signals, such as the pressure of hydraulic systems and the contact pressure of robotic arms, helping robots to perform tasks more accurately and stably.
• Internet of Things (IoT): Applied in IoT devices, it can collect pressure data in different environments, such as the air pressure monitoring in smart homes, environmental pressure detection in smart agriculture, etc., providing data support for intelligent decision - making.
• Portable Instruments: Suitable for portable pressure - measuring instruments. Due to its low - power characteristics, it can extend the battery life of portable devices, and its high - precision measurement can meet the needs of various on - site measurement scenarios.

Features:

• High - Precision Measurement: Most models, such as ADS1115 and ADS1146, have a 16 - bit resolution, which can provide high - accuracy measurement results, crucial for applications requiring fine - tuning, and can ensure the accuracy of pressure readings.
• Multiple Input Channels: Devices like ADS1115 have multiple input channels, which can realize multi - channel acquisition, allowing for the simultaneous monitoring of multiple pressure points, improving the reliability and stability of the system, and are suitable for complex measurement scenarios.
• Low Power Consumption: ADS1110 has a typical current consumption of only 240 μA, and some models can also operate in low - power modes, which is very important for applications that need to run for a long time, such as battery - powered devices, and can extend the service life of the equipment.
• Good Anti - interference Ability: Many models, such as ADS1146, have a 50/60 Hz rejection function. The digital filter can suppress 50Hz and 60Hz interference, which is suitable for noisy industrial application environments and can ensure the stability of measurement data.
• Programmable Gain: Models such as ADS1120 - Q1 and ADS1146 are equipped with a programmable gain amplifier (PGA), with a gain of up to 128V/V. It can adjust the dynamic range of input signals according to application requirements, improving the flexibility of signal processing.
• Convenient Communication Interface: ADS1115 uses the I2C communication protocol, and ADS1146 uses the SPI interface. These are common serial communication standards, which can simplify the connection complexity with micro - controllers, facilitating system integration and reducing system complexity and cost.
