Baumer CB Bimetal Temperature Gauge

A. Product Overview

The Baumer CB bimetal temperature gauge is a mechanical temperature measuring instrument used for reliable local temperature monitoring in industrial applications. It is suitable for measuring process temperature from -80 to 500 degree C without requiring external power supply.

This model is available in nominal size options of 40, 50, 63, 80, 100, 125 and 150 mm, allowing selection based on visibility, installation space and application requirement. The gauge comes with an AISI 304 SS case as standard, with optional AISI 316 SS case for more demanding environments. It uses an AISI 316 SS sensing element, making it suitable for general industrial and corrosive service conditions.

The Baumer CB temperature gauge supports stem lengths from 30 to 600 mm and process connection options of 3/8 inch and 1/2 inch BSP and NPT. It is available with mounting options 2, 4, 8 and 14, giving flexibility for bottom, back and panel type installations depending on the site requirement.

B. Working Principle

The Baumer CB bimetal temperature gauge works on the bimetallic expansion principle. Inside the stem, a bimetal sensing element is made from two different metals bonded together. These metals expand at different rates when exposed to temperature changes.

When the process temperature increases or decreases, the bimetal element twists or bends due to unequal thermal expansion. This movement is transferred to the pointer through a mechanical linkage. The pointer then moves across the dial and displays the process temperature directly.

Since it is a mechanical temperature gauge, it does not require electricity, battery power or external signal input. This makes it suitable for simple, continuous and reliable local temperature indication in industrial plants.

C. Why It Is Used

The Baumer CB bimetal temperature gauge is used to monitor process temperature directly at the installation point. It is useful where operators need quick visual temperature readings without depending on electronic instruments.

It is commonly used because it provides:

Reliable local temperature indication
No external power requirement
Wide temperature measurement range from -80 to 500 degree C
Stainless steel construction for industrial environments
AISI 316 SS sensing element for better durability
Multiple dial sizes for better visibility
Flexible stem length options from 30 to 600 mm
