Baumer UT Bellows Pressure Switch

A. Product Overview

The Baumer UT Bellows Pressure Switch is a mechanical pressure switch used for monitoring and controlling pressure in industrial systems. It is suitable for pressure ranges from 0 to 30 bar and offers 2.0 percent FSR repeatability, making it a reliable choice for general utility pressure applications.

This pressure switch uses a phosphor bronze bellows sensing element that responds to pressure changes and activates a 1 microswitch SPDT contact. The switch rating is 15 A at 220 VAC and 10 A at 24 VDC, allowing it to be used with alarms, pumps, compressors, control panels and automation circuits.

The Baumer UT pressure switch comes with a 1/4 inch BSP or NPT process connection, steel plated body and plastic cover. With IP32 protection, it is suitable for protected industrial environments where basic dust and drip resistance is required.

B. Working Principle

The Baumer UT Bellows Pressure Switch works on a mechanical bellows movement principle. When pressure enters through the process connection, it acts on the phosphor bronze bellows inside the switch. As the pressure increases or decreases, the bellows expands or contracts.

This movement is transferred to the internal switching mechanism. When the pressure reaches the set point, the SPDT microswitch changes its contact position. This contact change can be used to start or stop equipment, trigger an alarm, cut off a circuit or send a signal to a control panel.

When the pressure returns below or above the reset point, the microswitch comes back to its original position. This makes the Baumer UT pressure switch useful for automatic pressure control and safety interlocking.

C. Why It Is Used

The Baumer UT Bellows Pressure Switch is used to provide dependable pressure-based switching in industrial equipment and process systems. It helps protect machines and systems from low pressure, high pressure or abnormal pressure conditions.

It is commonly used because it is compact, simple to install and suitable for direct switching applications. The SPDT output allows the user to connect the switch for either normally open or normally closed operation depending on the control requirement.

This pressure switch is useful in applications where a mechanical pressure control device is preferred over an electronic transmitter. It does not require complex programming and can be used in basic automation, pump control, compressor control and equipment protection systems.
