Detailed Product Description
1. Digital Communication (IO-Link)
This is the standout feature of the PE 7003. IO-Link is a point-to-point serial communication protocol that allows for far more than just transmitting a pressure value.
-
Rich Data: It transmits the exact measured pressure value, device status, and diagnostic information.
-
Parameterization: All device settings (e.g., measuring range, switching thresholds, response time) can be stored digitally and downloaded to the sensor. This makes device replacement incredibly easy (“cloning”).
-
Advanced Diagnostics: Provides information on operating hours, temperature warnings, and potential errors, enabling predictive maintenance.
2. Versatile Operating Modes
The transmitter can be configured in several ways to suit the application:
-
IO-Link Mode: For full digital integration into modern Industry 4.0 and IIoT environments.
-
Standard Mode (SIO): If the controller does not support IO-Link, it can operate as a standard device with:
-
Two switching outputs (PNP)
-
One switching output and one analog output (0…10V or 4…20mA)
-
3. Robust Design
-
Housing: Made from high-quality stainless steel (V4A / AISI 303), making it suitable for harsh industrial environments, including washdown areas in food & beverage or chemical applications.
-
Sealing: The IP67/IP69K rating ensures it is protected against dust, temporary immersion, and high-pressure/steam cleaning.
4. User-Friendly Operation
The integrated LCD display allows for:
-
At-a-glance viewing of the current pressure.
-
Simple on-site setup and configuration of switching points and other parameters using the button on the device.
-
Clear visualization of the device status and any error messages.
Typical Applications
The PE 7003 G 1/4 is used in countless industries and machines, including:
