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

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

A: The Series 251 can be mounted on a wall or panel using the provided mounting hardware. Its dual 1/4" NPT female process connections make integration with pipelines straightforward, while screw terminals allow for secure electrical connection to your power and monitoring system.

Q: What media can the Series 251 transmitter measure pressure for?

A: This transmitter is designed to measure differential pressure in both liquids and gases. Its wet/wet sensor design with Buna-N seals and stainless steel wetted parts ensures compatibility with a variety of industrial fluids and air systems.

Q: When should I use an external zero or span adjustment?

A: External zero and span adjustments allow on-site calibration to counteract installation effects or minor sensor drift over time. It is recommended to check and calibrate during initial installation, after significant changes in the process, or as part of routine maintenance.

Q: Where can the Series 251 be used given its operating range?

A: The transmitter operates reliably in ambient conditions from -20C to +85C and within a compensated range of 0C to +70C, making it suitable for industrial applications such as HVAC, process control, or water management systems in various settings across India.

Q: What are the benefits of using a 4-20 mA output signal?

A: The 4-20 mA analog output provides reliable and interference-resistant transmission of the pressure signal over long cable runs common in industrial installations. This standard output is easily integrated with most control systems, enabling straightforward monitoring and control.

Q: How does the transmitter handle overpressure situations?

A: The Series 251 is rated for a maximum overpressure of 500 PSI, providing robust protection against pressure surges and process upsets to maintain transmitter integrity and measurement accuracy.

Q: What makes the Sensocon 251 suitable for industrial environments?

A: With an IP65 ingress protection rating, anodized aluminum housing, and compatibility with both aggressive and non-aggressive media, the Series 251 is engineered to endure demanding conditions in manufacturing, processing, and utility industries.
