This durable design assures long service life and consistent performance, reducing maintenance downtime.

Flexible and Simple Installation

The Sensocon Series 251-07 includes a mounting bracket and features 1/4" NPT female connectors for straightforward integration into existing infrastructure. Electrical connections are handled via a secure terminal block, enabling quick setup. With a broad 12-36 VDC power supply range and compact size, it fits tightly in constrained spaces, supporting both wall and panel mount configurations.

FAQs of Sensocon USA Wet/Wet Differential Pressure Transmitter Series 251-07:

Q: How do I install the Sensocon Series 251-07 differential pressure transmitter?

A: The transmitter can be wall or panel mounted using the included mounting bracket. Use the 1/4" NPT female connectors for pressure lines and connect the power supply (12-36 VDC) and signal wires to the terminal block. Ensure the device is securely fastened and the O-ring seals are properly seated for reliable performance.

Q: What types of media can the Sensocon 251-07 measure?

A: This sensor is compatible with both liquids and gases, making it versatile in various industrial applications such as fluid flow monitoring, filtration, pump control, and process automation where wet/wet differential pressure measurement is required.

Q: Where can the transmitter be used considering its environmental ratings?

A: Thanks to its IP65 (NEMA 4X) enclosure and wide temperature operating range (-4F to 185F), the Series 251-07 can be installed in harsh industrial environments including outdoor locations, chemical facilities, plant rooms, or water treatment installations.

Q: What is the benefit of the 4-20 mA 2-wire output signal?

A: The 4-20 mA 2-wire output offers long-distance signal transmission with minimized signal loss. This industry-standard output is easy to integrate with existing process control systems and supports diagnostic capabilities for enhanced fault monitoring.

Q: When should I use a wet/wet differential pressure transmitter over a dry type?

A: A wet/wet transmitter is preferable when both sides of the sensor will be exposed to fluids, especially in applications involving corrosive or conductive media. This ensures prolonged sensor integrity and measurement reliability.

Q: What level of measurement accuracy can I expect from this device?

A: The Sensocon 251-07 delivers a measurement accuracy of 1% full scale, with excellent linearity and minimal hysteresis (0.5% FS), making it suitable for critical industrial process management requiring precise pressure data.
