Product Specifications

Technical details and manufacturing context for Pressure Sensors

Definition
Pressure sensors are critical components in gas flushing units and vacuum pumps that detect, measure, and provide feedback on pressure conditions within the system. They ensure proper vacuum levels are maintained during gas flushing operations and monitor pressure differentials to optimize performance and safety.
Working Principle
Pressure sensors typically operate by converting mechanical pressure into electrical signals. Common technologies include piezoresistive, capacitive, or piezoelectric elements that deform under pressure, creating measurable electrical changes that are calibrated to specific pressure ranges.
Common Materials
Stainless steel housing, Silicon sensing element, Ceramic substrate
Technical Parameters
  • Pressure measurement range typically from vacuum (0 bar absolute) to 10 bar gauge pressure (bar) Per Request
Components / BOM
  • Sensing Element
    Converts pressure into electrical signal through deformation or capacitance change
    Material: Silicon or ceramic
  • Diaphragm
    Flexible membrane that transfers pressure to sensing element
    Material: Stainless steel or silicon
  • Signal Conditioning Circuit
    Amplifies and processes raw electrical signals from sensing element
    Material: Printed circuit board with electronic components
  • Housing
    Protects internal components from environmental factors and provides mounting interface
    Material: Stainless steel or aluminum
Engineering Reasoning
0-100 bar absolute pressure
150 bar burst pressure for diaphragm sensors, 200°C maximum operating temperature for piezoresistive sensors
Design Rationale: Diaphragm plastic deformation exceeding 0.2% strain limit at 150 bar, semiconductor junction thermal breakdown at 200°C for silicon piezoresistive elements
Risk Mitigation (FMEA)
Trigger Condensate accumulation in pressure port
Mode: Zero-point drift exceeding ±0.5% FS/day
Strategy: Integrated heating element maintaining port temperature 20°C above dew point
Trigger Electromagnetic interference from variable frequency drives
Mode: Signal noise exceeding 10 mV RMS at 4-20 mA output
Strategy: Triple-shielded cable with ferrite cores at both ends

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Drift/Calibration Loss
Cause: Thermal cycling, mechanical stress, or contamination causing diaphragm deformation or strain gauge degradation, leading to inaccurate pressure readings over time.
Electrical Failure
Cause: Moisture ingress, corrosion, or vibration-induced damage to wiring, connectors, or internal electronics, resulting in signal loss, noise, or complete sensor failure.
Maintenance Indicators
  • Erratic or fluctuating pressure readings inconsistent with process conditions
  • Zero or full-scale output when pressure is applied or removed
Engineering Tips
  • Implement regular calibration checks using traceable standards, especially after temperature extremes or mechanical shocks, to detect and correct drift early.
  • Ensure proper sealing of electrical connections and use vibration-resistant mounting to protect internal components from environmental stressors.

Compliance & Manufacturing Standards

Reference Standards
ISO 9001:2015 - Quality management systems CE Marking (EU Directive 2014/35/EU) - Electrical equipment safety ASTM E74-18 - Calibration of force-measuring instruments for verifying the force indication of testing machines
Manufacturing Precision
  • Pressure accuracy: +/-0.25% full scale
  • Temperature compensation: +/-1.0°C over operating range
Quality Inspection
  • Pressure calibration test against traceable standards
  • Environmental stress screening (temperature, humidity, vibration)
