FAQs of Sensocon USA Wet/Wet Differential Pressure Transmitter Series 251-01:

Q: How is the Sensocon Series 251-01 differential pressure transmitter installed?

A: The Series 251-01 is designed for wall or panel mounting using the included hardware. Its side port connections accept 1/4 NPT female fittings, while screw terminals simplify electrical wiring. Always refer to the datasheet for detailed dimension and installation instructions.

Q: What media can the transmitter measure, and how does the wet/wet design benefit users?

A: This transmitter can accurately measure the differential pressure of both liquids and gases. Its wet/wet sensor design and use of stainless steel wetted parts, along with Viton O-rings, ensure compatibility with a wide variety of fluids and resist corrosion, making it suitable for many industrial processes.

Q: When should I consider this transmitter over dry/wet types?

A: Use the Series 251-01 when both pressure ports will be exposed to liquids or gases, especially if there is potential for media compatibility concerns. Its construction is optimized for reliability and accuracy in environments where dry/wet sensors may be unsuitable due to fluid contact.

Q: Where can the Sensocon 251-01 be installed for optimal performance?

A: The transmitter can be mounted in both indoor and outdoor industrial locations thanks to its NEMA 4X (IP66) rated enclosure. For best results, install near your pressure source and in a spot protected from extreme mechanical damage.

Q: What are the process benefits of using the Sensocon 251-01 series?

A: Key benefits include rapid response to pressure changes (<10ms), high accuracy (1% FS), stable long-term measurements (0.5% FS/year), and robust construction. These features support critical process monitoring, improve control accuracy, and contribute to reduced maintenance downtime.

Q: How is calibration managed for this transmitter?

A: Each unit is OEM/factory calibrated before shipment. This ensures that the device delivers reliable, out-of-box performance without the need for immediate field calibration, contributing to straightforward commissioning.
