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.
Features
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
