The **M6SWVS-35-R/Q** is a high-precision, industrial-grade pressure transducer (sensor) typically manufactured by **GE (General Electric) / Druck**. It is widely used in aerospace and automotive testing environments due to its stability and accuracy. ### 1. Technical Specifications The part number indicates specific characteristics regarding its pressure range, output, and electrical configuration. | Feature | Specification | | :--- | :--- | | **Manufacturer** | GE Druck | | **Pressure Range** | 0 to 35 bar (Varies slightly by sub-series) | | **Type** | Gauge or Absolute Pressure Sensor | | **Output Type** | Millivolt (mV) - Ratiometric | | **Bridge Impedance** | Typically 5000 Ohms | | **Operating Temp** | -54°C to +121°C | | **Accuracy** | High Precision (Linearity/Hysteresis < 0.1%) | --- ### 2. Internal Electronic Architecture This sensor utilizes **Silicon Piezoresistive** technology. Here is how the electronic components function: * **Piezoresistive Bridge:** The core is a micromachined silicon diaphragm with four integrated strain gauges arranged in a **Wheatstone Bridge** circuit. * **Excitation:** It requires a stable external DC voltage (typically 10V DC). The output is proportional to the input voltage. * **Compensation Resistors:** These are internal laser-trimmed resistors used to minimize "Zero Shift" and "Span Shift" caused by temperature fluctuations. * **Signal Conditioning:** As an "R/Q" variant, it usually provides a raw millivolt output, meaning the user must provide external amplification or interface it with a high-resolution ADC (Analog-to-Digital Converter). --- ### 3. Pinout and Connectivity (Standard R/Q Wiring) Most units in this series use a 6-pin or 4-wire configuration: | Wire Color / Pin | Function | Description | | :--- | :--- | :--- | | **Red** | + Excitation | Input Voltage (Positive) | | **White** | - Excitation | Input Voltage (Negative/Ground) | | **Yellow** | + Output | Positive Signal (mV) | | **Blue/Green** | - Output | Negative Signal (mV) | --- ### 4. Application Use Cases * **Aerospace Testing:** Monitoring hydraulic fluid pressure in flight control systems. * **Automotive R&D:** Measuring oil or fuel pressure during engine dynamometer testing. * **Calibration:** Used as a reference standard in pressure secondary laboratories.
