Technical details and manufacturing context for Pressure Sensor/Transducer

Definition
A critical component within a Pressure Testing Unit that detects and measures fluid or gas pressure, converting it into a standardized electrical output signal (e.g., 4-20mA, 0-10V) for monitoring, data acquisition, and control systems to ensure testing accuracy and safety.
Working Principle
Typically operates on principles such as piezoresistive, capacitive, or strain gauge. Applied pressure causes a physical deformation in a sensing element (diaphragm), which changes its electrical properties (resistance, capacitance). This change is measured by an internal circuit and converted into a proportional electrical output signal.
Common Materials
Stainless Steel (housing/diaphragm), Silicon (piezoresistive sensing element), Ceramic (capacitive sensing element)
Technical Parameters
  • Pressure range (e.g., 0-100 bar) (bar, psi, kPa, MPa) Per Request
Components / BOM
  • Pressure Sensing Diaphragm
    The primary element that deflects under applied pressure, initiating the measurement process.
    Material: Stainless Steel, Silicon, or Ceramic
  • Strain Gauge / Piezoresistor
    Attached to the diaphragm; changes electrical resistance in response to diaphragm strain.
    Material: Silicon, Metal Foil
  • Signal Conditioning Circuit (ASIC)
    Amplifies, linearizes, and temperature-compensates the raw signal from the sensing element, converting it to the standard output.
    Material: Semiconductor (Silicon)
  • Housing / Body
    Protects internal components from the environment and provides mechanical mounting and process connection.
    Material: Stainless Steel, Aluminum, Plastic
  • Electrical Connector / Cable
    Provides the interface for power supply and output signal transmission to the control system.
    Material: Brass, Plastic, Copper
Engineering Reasoning
0-100 bar absolute pressure
150 bar burst pressure for diaphragm rupture
Design Rationale: Diaphragm plastic deformation exceeding yield strength of 316L stainless steel (205 MPa) at 150 bar differential pressure
Risk Mitigation (FMEA)
Trigger Condensation ingress into sensor cavity
Mode: Bridge circuit short circuit
Strategy: Hermetic sealing with laser-welded 316L stainless steel housing rated to IP68
Trigger Thermal cycling between -40°C and 125°C
Mode: Wheatstone bridge resistor drift exceeding 0.1% FS
Strategy: Temperature-compensated piezoresistive silicon chip with 0.02%/°C TCR matching
