4738 - Electric differential pressure switch

The Type 4738 electric differential pressure switch is limit switch which issues an electrical limit signal whenever a certain limit of the differential pressure, pressure or vacuum is reached. This signal is used to control an audible or visual alarm, signal processing and closed or open-loop control equipment.

It is designed for liquids, gases and steams as well as differential pressure, pressure and vacuum set points from 35 to 400 mbar with operating pressures up to 10 bar.

• Housing: GD AlSi12
• Max operating pressure: 10 bar, short-term overload up to 16 bar
• Adjustable limit values: 35 to 160 mbar or 160 to 400 mbar
• Permissible ambient temperature: max 50 °C
