Overview of 1240-015A-3S

The 1240-015A-3S is a board mount pressure sensor designed for precise measurement of pressure in industrial, medical, and environmental applications. This sensor provides accurate pressure readings in a small form factor, making it ideal for integration into compact systems. It is suitable for applications requiring low-pressure monitoring and control, such as HVAC systems, medical devices, and industrial automation. The sensor's robust design ensures consistent performance and long operational life in harsh environments.

Pinout

The 1240-015A-3S comes in an 8-pin DIP Module configuration for easy mounting on printed circuit boards (PCBs). Key pin functions include:

  • VCC (Power Supply): Provides the operating voltage to the sensor.
  • GND (Ground): Common ground for stable sensor operation.
  • Pressure Output (Analog/Digital): The output signal corresponding to the measured pressure, which can be either analog or digital depending on the variant.
  • I2C/SPI Interface Pins: Optional communication pins for digital variants, used for data transmission and control in systems with I2C or SPI protocols.

This configuration allows for easy interfacing with microcontrollers and other processing units in embedded systems.

Features

  • High-Precision Pressure Sensing: Provides accurate pressure measurements with a sensitivity of ±1% full scale.
  • Wide Pressure Range: Measures pressures up to 15 PSI, making it versatile for both low and moderate pressure applications.
  • Compact Board Mount Design: The small DIP-8 form factor allows for easy integration into space-constrained systems.
  • Analog or Digital Output: Offers flexibility with either analog voltage output or digital communication via I2C/SPI.
  • Low Power Consumption: Optimized for energy efficiency in battery-powered or low-power systems.
  • Robust Build: Designed to operate reliably in demanding environments, with high resistance to mechanical stress and thermal variation.

Applications

  • Medical Devices: Used for monitoring and controlling pressure in medical equipment such as ventilators and anesthesia systems.
  • HVAC Systems: Provides accurate pressure monitoring for air flow and pressure control in heating, ventilation, and air conditioning systems.
  • Industrial Automation: Ideal for monitoring and regulating pressure in automated processes and machinery.
  • Environmental Monitoring: Suitable for weather stations and other systems that track atmospheric pressure.
  • Aerospace: Used in aerospace applications where precise pressure readings are critical for safety and performance.

Functionality

The 1240-015A-3S operates by detecting the pressure exerted on its sensing element and converting it into an electrical signal. This signal can be either analog or digital, depending on the sensor variant. In analog mode, the output voltage is directly proportional to the measured pressure. In digital mode, the sensor communicates with the system via I2C or SPI, providing high-resolution pressure data. This makes it ideal for applications that require real-time pressure monitoring and control.

Advantages

  • High Accuracy: Provides precise pressure measurements, critical for applications where accuracy is paramount.
  • Flexible Output Options: Available with both analog and digital outputs, giving system designers flexibility in integration.
  • Compact and Easy to Install: The small DIP-8 package makes it easy to mount on PCBs, even in space-constrained environments.
  • Energy Efficient: Low power consumption allows for long-term use in battery-operated devices.
  • Reliable in Harsh Environments: Built to withstand fluctuations in temperature and mechanical stress, ensuring long-term durability.
