The **PTPH-86A-R/Q** is a high-precision pressure transducer, typically utilized in industrial automation and hydraulic control systems. While specific technical data sheets may vary slightly by manufacturer (often associated with brands like Parker or specific pneumatic/hydraulic specialists), the "86A" series generally refers to a ruggedized electronic pressure sensor. --- ### 1. Core Specifications The following table highlights the typical electronic and physical characteristics of this part series: | Feature | Specification | | :--- | :--- | | **Output Signal** | Typically 4-20 mA or 0-10 VDC | | **Supply Voltage** | 12 - 30 VDC (regulated) | | **Pressure Range** | Varies by sub-model (Commonly 0-250 bar or 0-400 bar) | | **Accuracy Class** | 0.5% or 1.0% FS (Full Scale) | | **Electrical Connection** | M12 Circular Connector or DIN 43650 | | **Operating Temp** | -20°C to +85°C | --- ### 2. Internal Electronic Components The device functions through a series of integrated electronic stages: 1. **Sensing Element:** Usually a **Piezoresistive** or **Thin-film strain gauge** bridge. When pressure is applied, the resistance changes proportionally. 2. **Signal Conditioning (ASIC):** An internal Application-Specific Integrated Circuit (ASIC) amplifies the millivolt signal from the sensor. 3. **Temperature Compensation:** Internal thermistors or compensation circuits ensure the output remains stable even as the ambient temperature fluctuates. 4. **EMI/RFI Filtering:** Capacitors and ferrites are included on the PCB to protect the sensor from electromagnetic interference common in industrial environments. --- ### 3. Suffix Breakdown (R/Q) In industrial electronic nomenclature, these suffixes often denote specific internal configurations: * **-R:** Generally indicates a **Regulated** output or a specific **Reverse-polarity protection** circuit to prevent damage during installation. * **-Q:** Often refers to a **Quick-connect** electrical interface (like an M12 4-pin connector) or a specific **Quality certification** (like a factory calibration certificate). --- ### 4.
