Lefoo Digital Pressure Switch LFDS10

Name: Digital Pressure Switch LFDS10
Brand: LEFOO INDUSTRIAL CO.,LTD.
Rating: 4.8 (50 reviews)

LEFOO LFDS101/LFDS102 series adopt a high-reliability transmitter to measure pressure, and the signal is processed by a back-end circuit and converted into a standard industrial electrical signal for output and display.

This digital pressure switch is in fully engineering plastic housing design, high contrast, dual-screen LCD digital display, the 3-key design, and user-friendly menu make the product more convenient to operate, and a variety of connection modes can fully meet various specific installation requirements. Many built-in setting items can be set by the user to adjust the working parameters, which is flexible and convenient.

This series of pressure switches have characteristics of anti-vibration, long lifetime, simple operation, clear display, etc. It can be used in a variety of industrial applications, such as industrial systems to confirm the adsorption of electronic parts, to confirm the total pressure, or to detect air leakage.
