0 – 5Vdc, 5″wc to 100 psi
Viatran’s 244 sensor is a low range pressure transducer designed for the test market. The 244 features highly accurate pressure measurement in ranges from 5 ” WC to 100 PSI. The unique variable capacitance technology allows for extreme overpressure protection up to 500 PSI.
Features
High Accuracy
Many Options available
Low Pressure Applications
The Model 244 offers a 0 to 5 Vdc signal.
Using our variable capacitance technology, the Model 244 transducer provides extreme overpressure protection up to 500 PSI.
This sensor design provides standard accuracy of <±0.15% FSO.
The unit also offers standard temperature performance to ±2%/100° F with an improved option to±1%/100° F.
All wetted surfaces of the X44 Series are constructed with 316 stainless steel, making them ideal for wet/wet applications.
In environmental test chambers, these surfaces withstand contaminants such as water vapor, oil, exhaust or mists.
Atmospheric reference is specially constructed to withstand the ingress of moisture, ensuring accurate pressure measurement.
Model 244 features an internal calibration circuit for easy field set-up, a quick disconnect electrical connection and external zero and span controls.
These features allow you to calibrate the transducer without an external pressure source and eliminate the need to send the unit to a metrology lab for calibration.
