Product Description

Series 616KX Differential Pressure Transmitters: High-Precision Monitoring for Critical Applications

The 616KX Series Differential Pressure Transmitters offer installers and maintenance professional's Maximum Flexibility in Pressure Ranges within a compact design. As Dwyer's smallest differential pressure transmitter, it ensures simplicity with an edge-mounted push-button zero for easy access in any mounting configuration and features field-selectable output signals. The molded housing supports three sizes of both imperial and metric process connections, with optional 1/8³ NPT or BSPT Threaded models, ensuring easy and flexible process connections.

The 616KX Series ensures exceptional stability and repeatability, minimizing drift and enhancing long-term reliability. The robust construction enables operation in demanding conditions, while the user-friendly interface allows for easy installation and calibration. Available in multiple ranges and outputs, these transmitters seamlessly integrate into existing systems, providing real-time monitoring and control.
