APPLICATION GUIDE // RAILWAYS & TRANSPORTATION

Pressure Transmitters for Railway Applications

Electric locomotives, EMU passenger coaches, electropneumatic braking & coach water tanks

THE OPERATING CHALLENGE

Why Standard Catalog Sensors Often Fail in this Application

Rolling stock environments experience extreme shock and vibration, wide ambient temperature fluctuations (-40°C to +85°C), and severe electrical spikes from traction motors.

PROCESS PARAMETER PROFILEENGINEERING BASELINE
Typical Working Range:0–10 bar (Braking main reservoir), 0–2.5 mH2O (Coach water tank level)
Process Media:Brake line compressed air, potable coach water
Fluid & Ambient Temp:-40°C to +85°C
Primary Failure Risk:Track vibration shock (EN 61373 Category 1 Class B) and wide DC supply surges
ENGINEERING SELECTION CHECKLIST

What to Specify When Ordering for this Process

  • Compliance with EN 50155 electronic equipment used on rolling stock
  • Compliance with EN 61373 vibration and shock resistance
  • High insulation breakdown resistance (>100 MΩ at 500 VDC)
  • Reverse polarity and overvoltage suppression circuitry
ACT FIELD INSTALLATION ADVICE

ACT provides customized mounting brackets and reinforced conduit-ready cable boots to ensure long service life underneath locomotive underframes.
