FAQs of Sensocon USA Wet/Wet Differential Pressure Transmitter Series 251-02:

Q: How does the Series 251-02 transmitter measure differential pressure in wet/wet applications?

A: The Series 251-02 uses solid-state electronic sensors to evaluate pressure differences between two wet media points, enabling the monitoring of liquids or gases in industrial piping or HVAC systems.

Q: What are the primary benefits of using the 251-02 differential pressure transmitter?

A: Key advantages include high accuracy (1% of full scale), robust anodized aluminum and 316L stainless steel construction, NEMA 4X (IP65) environmental protection, and quick adjustments for zero and span, making it ideal for industrial and HVAC monitoring tasks.

Q: When should this transmitter be selected for a process control application?

A: Choose the Series 251-02 when you need to monitor the differential pressure of two wetted process lines, especially in systems where both sides may contain liquid or gas under pressure, and reliability and accuracy are crucial.

Q: Where can the Series 251-02 be installed and what mounting options are available?

A: This transmitter can be wall- or surface-mounted using the included bracket. Its compact, cylindrical design and durable enclosure suit both indoor and outdoor industrial or commercial locations.

Q: What is the process for zero and span adjustment on this device?

A: Zero and span can be adjusted externally via conveniently located push buttons. This feature allows operators to calibrate the transmitter quickly without dismantling or removing it from service.

Q: How is the electrical output configured for integration with monitoring systems?

A: The device outputs a standard 4-20 mA signal (2-wire), making it compatible with most industrial control and data acquisition systems. It requires a 12-36 VDC power supply.

Q: What types of media can the 251-02 measure and what materials are in contact with process fluids?

A: Its suitable for both liquids and gases in wet/wet applications. Media-contacted parts are made of 316L stainless steel and Viton, ensuring resistance to corrosion and chemical compatibility in demanding environments.
