Model 24A - Pressure Transmitter

The Viatran 24A pressure transducer is a highly adaptable silicon sensor with an output of 0-5 Vdc, and 3000-5000  psi (0.2 to 345 bar). It can be used efficiently in a host of industrial settings, because of the wide range of pressure measurements with a standard linearity measuring ±0.25% FSO or less. Additionally, even higher linearities of ±0.15% or ±0.10% FSO may be requested. Again, apart from the standard output signal range of 0-5 Vdc, other options are available.


The Viatran model 24A offers:

  • Flexibility for applications at low pressure
  • Excellent precision
  • Conformity with RoHS standards
  • Multiple options for linearity and output signal range
  • Constructed wholly of stainless steel
  • An optional circuit for calibration of the shunt

Representative Uses

The 24A is commonly used for applications such as:

  • Hydraulic devices
  • Pumps and compressors
  • Rolling mills
  • Die cast processes
  • Test stands for production or engines
