The **PTPH-6GA-R** is a high-performance, precision pressure sensor (transducer) typically utilized in industrial, automotive, and medical applications. It is designed to convert physical pressure into a measurable electrical signal with high accuracy. ### 1. Technical Specifications The following table outlines the primary electrical and physical characteristics of the PTPH-6GA-R: | Feature | Specification | | :--- | :--- | | **Sensor Type** | Pressure Transducer / Piezo-resistive | | **Pressure Range** | 0 to 6 Bar (Gage) | | **Output Type** | Analog Voltage / Bridge Output | | **Accuracy** | High Precision (Linearity/Hysteresis) | | **Housing Material** | Stainless Steel or Robust Polymer | | **Connection Type** | Threaded fitting / PCB Pins | --- ### 2. Core Electronic Components The device operates using a combination of specialized electronic structures: * **Piezo-resistive Element:** The heart of the sensor is a silicon-based diaphragm with integrated resistors. When pressure is applied, the diaphragm deforms, changing the resistance of the elements (the Piezo-resistive effect). * **Wheatstone Bridge Circuit:** The internal resistors are arranged in a bridge configuration to provide a differential voltage output. This maximizes sensitivity and minimizes the effects of temperature fluctuations. * **Signal Conditioning (ASIC):** Most "R" suffix models include an internal Application Specific Integrated Circuit (ASIC) for: * **Amplification:** Boosting the millivolt signal to a usable level. * **Temperature Compensation:** Correcting for errors caused by heat. * **Calibration:** Ensuring the output is linear relative to the input pressure. --- ### 3. Pin Configuration & Wiring While specific pinouts can vary by manufacturer variants, a standard 4-pin or 3-pin configuration is typical: ```text Pin 1: Vcc (Supply Voltage, typically 5V or 10V DC) Pin 2: GND (Ground) Pin 3: Vout+ (Positive Signal Output) Pin 4: Vout- (Negative Signal/Reference) ``` ### 4. Typical Applications * **Industrial Automation:** Monitoring pneumatic lines or hydraulic fluid pressure. * **Medical Devices:** Used in oxygen concentrators or blood pressure monitoring systems. * **Automotive:** Manifold absolute pressure (MAP) or oil pressure sensing. ---
