Description
EQXPH is a versatile, easy-to-use DIN rail pH sensor expansion module designed for pH monitoring in industrial and environmental applications. It seamlessly integrates with the EQSP32 Industrial IoT controller, enhancing your automation setup with precise pH measurement capabilities.
The module features a standard BNC connector, compatible with a wide range of pH probes, and is automatically detected by the EQSP32 upon power-up, offering a plug-and-play experience. For best accuracy, the EQXPH module must be calibrated to match the selected probe. Whether monitoring water quality in industrial processes, managing environmental systems, or controlling chemical balances in laboratories, EQXPH delivers reliable, stable pH readings under varying conditions.
To further simplify setup and operation, EQXPH is fully supported by the EQ-AI generative AI model. EQ-AI assists in generating initialization code simply by describing your system’s external connections or uploading a wiring diagram. This powerful tool enables fast, AI-assisted code creation, saving time and ensuring accuracy in your programming.
Firmware updates for EQXPH pH sensor can be easily applied through its own front-facing USB-C port, ensuring you always have access to the latest features and performance improvements specific to the module. This field-upgradable firmware allows you to benefit from ongoing enhancements without affecting the main application running on the EQSP32 controller.
Key Features of EQXPH:
- BNC Connector: Quick and secure attachment for pH probes.
- Simple Calibration: Calibration process ensures accurate pH measurements for the selected probe.
- Field Upgradable Firmware: Firmware updates can be applied via the front-facing USB-C port, ensuring you always have access to the latest improvements specific to the module.
- Expandability: Users can add additional expansion modules as needed to extend functionality.
- Power and Status LEDs: Visual indicators provide easy monitoring of module status.
- Seamless Integration: Programming and integration are simplified through the provided library API and the EQ-AI code generation assistant.
- Automatic Detection: EQXPH pH sensor is automatically detected by EQSP32 upon power-up for a plug-and-play experience.
- Compact Design: Fits on standard DIN-rail.
- Connection: After mounting the module on the DIN-rail, simply slide it to connect with EQSP32 via the board to board connector.
