An ATM pressure sensor is a highly versatile, analog device specifically designed for accurate measurement of various pressure types, including gauge pressure, overpressure, and absolute pressure. Renowned for its adaptability, this sensor comes in a wide array of types, measuring ranges, and accuracy classes, making it suitable for diverse industrial and scientific applications.
Understanding the ATM Pressure Sensor
At its core, the ATM pressure sensor functions as a robust and reliable instrument for converting physical pressure into an electrical signal. Its analog nature means it provides a continuous output signal that directly corresponds to the detected pressure.
Key characteristics that define an ATM pressure sensor include:
- Universal Applicability: Designed to be adaptable across a broad spectrum of industries and measurement scenarios.
- Measurement Versatility: Capable of measuring:
- Gauge Pressure: Pressure relative to the ambient atmospheric pressure.
- Overpressure: Pressure exceeding a specified normal operating limit.
- Absolute Pressure: Pressure relative to a perfect vacuum.
- Configurable Options: Available in numerous configurations to meet specific application demands.
Technical Specifications and Flexibility
The design of the ATM pressure sensor emphasizes flexibility, allowing it to integrate seamlessly into various systems.
Output Signals
The sensor provides common electrical output options, ensuring compatibility with most control and monitoring systems:
- Voltage Output: Typically a 0-5V or 0-10V signal, commonly used for direct input into PLCs, data loggers, or display units.
- Current Output: Often a 4-20mA signal, preferred for long-distance signal transmission due to its resistance to electrical noise and line loss.
Electrical and Pressure Connections
Different electrical versions and pressure connections are available, providing mechanical and electrical compatibility for a wide range of installation requirements. This ensures that the sensor can be physically integrated into various piping systems, tanks, and equipment, and electrically connected to different control units.

Selecting the Right Pressure Sensor
When choosing a pressure sensor, particularly one as versatile as the ATM type, several factors need careful consideration:
| Feature | Consideration |
|---|---|
| Pressure Type | Gauge, Absolute, or Overpressure? |
| Measuring Range | What is the minimum and maximum pressure to be measured? |
| Accuracy Class | How precise does the measurement need to be (e.g., 0.1%, 0.5% full scale)? |
| Output Signal | Voltage (0-5V, 0-10V) or Current (4-20mA)? Compatibility with existing control systems. |
| Electrical Connection | Connector type (e.g., DIN, M12) and cabling requirements. |
| Pressure Connection | Thread type and size (e.g., G1/4", NPT), material compatibility with the media. |
| Media Compatibility | What fluid or gas will the sensor be exposed to? Ensure the sensor's wetted parts are resistant to corrosion. |
| Environmental Factors | Operating temperature, vibration, humidity, and potential for hazardous areas. |
