Model 246 Pressure Sensor

Model 246 Pressure Sensor

Viatran's 246 pressure sensor is an electronic pressure transmitter designed to accurately measure barometric pressure to within 0.01 in HgA. The 346 measures pressures over standard ranges of 25 in HgA to 32 in HgA. 

Inquiry system 

Configure your own product according to your requirements and needs. If you are unsure of the configuration, provide us in the notes the necessary information about the existing sensor or product, even a competitor. We will be happy to help you find an alternative Viatran product. If your request is urgent, let us know.
