Mechanical temperature (bimetal thermometers)

The simplest way to measure temperature (Mechanical temperature) in an industrial application is to use a bimetallic thermometer. The bimetallic thermometer works with two linked metal bands that have different coefficients of expansion and are threaded helically and connected directly to the dial, one of the bands will expand faster than the other, which generates a torque that causes the pointer to move over the dial and mark a temperature.

Bimetallic thermometers

Are the most economical solution for most industrial temperature measurement applications. Also, the hermetically sealed housing offers environmental protection. Standard stem lengths range from 2 ½” to 72″, with 3″ or 5″ diameter dials available.

Standard features of bimetallic thermometers (mechanical temperature):

• Dial Sizes: 3″ and 5″.
• Housing and Stem: 304 stainless steel, with or without external adjustment
• Visor: Safety laminated, acrylic and polycarbonate visor
• Dial: White aluminum
• Needle: Black aluminum
• Accuracy: +/- 1.0% of span
• 4″, 6″, 9″, 9″, 12″, 15″, 18″, 24″ bulbs
• 1-year warranty
• Dual scale (°F and °C)
• Single scale (°F or °C)

Column thermometers

Column thermometers are widely used in industrial hot water systems and air conditioning applications.

Features and specifications:

• Separable brass, lead free brass or stainless steel thermowell
• Rugged ABS plastic case
• Organic liquid indicator, can be blue, green or red colored
• Dual scale (°F and °C)
• Vertical or rear connection can be equalized
• 1/2″ NPT process connection
• Manufactured to ASME B40.200 ASTM E2251 standard
• 5-year warranty

Accessories for thermometers:

We keep thermowells in stock. These accessories are used to protect the bulb and allow the thermometer to be changed and/or disassembled in operation.

Thermowells can be threaded, weld-on or flanged.
