The **AP-H10-R** is a high-performance, compact **Pressure Sensor Head** (specifically a positive pressure type) from Keyence’s AP-V10/H10 series. It is designed to convert physical air pressure into an electrical signal for industrial automation. --- ### 1. Core Electronic Components & Architecture The AP-H10-R functions through several key electronic stages: | Component | Function | | :--- | :--- | | **Piezoresistive Element** | The core silicon diaphragm that changes resistance when pressure is applied. | | **Bridge Circuit** | A Wheatstone bridge configuration that converts the resistance change into a voltage signal. | | **Temperature Compensation** | Internal circuitry that corrects signal drift caused by environmental heat. | | **Signal Amplifier** | Boosts the millivolt output of the sensor to a level usable by the evaluation unit. | ### 2. Technical Specifications Below are the primary electronic and physical specifications for the AP-H10-R: | Feature | Specification | | :--- | :--- | | **Pressure Type** | Positive Pressure | | **Rated Pressure Range** | 0 to +1.000 MPa | | **Fluid Media** | Air or Non-corrosive gases | | **Cable Type** | Oil-resistant, 3-core cable | | **Weight** | Approximately 50g (including cable) | ### 3. Connection and Wiring The "R" in the model name often signifies a specific cable length or type (usually a 2m or 3m flexible cable). Electronic integration follows these principles: 1. **Analog Output:** The head itself provides a raw or pre-amplified analog signal to an **AP-C10 series** digital pressure monitor/amplifier. 2. **Power Supply:** Power is typically supplied through the amplifier unit (12–24V DC), meaning the sensor head does not require a separate external power source. 3. **Interface:** Uses a specialized connector designed for "plug-and-play" compatibility with Keyence evaluation units to ensure high noise immunity. ### 4. Signal Processing Logic * **Linearity:** The electronics are calibrated to ensure a linear relationship between the input pressure (0-1 MPa) and the output voltage. * **Response Time:** The electronic response is extremely fast, typically in the range of **1ms**, making it suitable for high-speed leak detection or vacuum verification. ---
