The Bimetal Thermometer employs a bimetal strip in the form of helix (it works on the principle of thermal expansion - two metals having different coefficient 

1, normally closed thermostat set the temperature point is "off temperature"If the product accuracy is ± 5 ℃,For example: we buy the product is 120 ℃,Then his disconnect temperature between 115 ℃ ~ 125 degrees, are qualified products.Reset the temperature of the relative accuracy will be much lower,General factory set reset temperature

Accuracy is good Less cost Temperature range is wide Linear response Robust and simple Disadvantages of Bimetallic Thermometer The disadvantages are If the measure in low

The bimetallic thermometer is an important temperature measuring instrument with a rugged yet straightforward structure. It is suitable for measuring at a temperature ranging from -50°C to 600°C. Following are the specifications of a bimetallic thermometer: The bimetallic thermometer provides high repeatability with an accuracy of ±1% FSD.

50%. Maximum temperature rating before thermometer accuracy may be impacted is x½ the upper temperature range value. Ex. 400°F + (400*½) = 600°F. 550°F to. 1000 

1/9 · To use the ice water method for calibrating bimetallic thermometers, fill a large glass with finely crushed ice. Add clean tap water to the top of the ice and stir well. Immerse the food thermometer stem a minimum of 2 inches into the mixture, touching neither the sides nor the bottom of the glass. Wait a minimum of 30 seconds before adjusting.

Application and Description. The bimetallic thermometers are used on site for direct temperature measurement. A wide range of standard ver-.

Accuracy is good Less cost Temperature range is wide Linear response Robust and simple Disadvantages of Bimetallic Thermometer The disadvantages are If the measure in low-temperature then they will give a less accurate result. If they handled roughly then calibration can be disturbed These are not suggested for above 400'C temperature.

A bimetallic stemmed thermometer is a temperature measuring device that uses a bimetallic strip to indicate temperature.

Rugged construction · Bottom/Back entry, every single angle construction · Fast response · Protection class IP-67 · Accuracy ± 1% FSD · High 

6/3 · As a general rule of thumb, the dry block or other source of accuracy should be four times better than the device under test. This is typical for most calibrations. Prerequisites 1 Hour Warm-up Time for Proper Stabilization Temperature: 23 +/- 5 deg C Humidity: 50 +/- 30% Perform 3 Trials for Each Point or Range Measurement Data Sheet (MDS)

MEASUREMAN Hot Water Bi-Metal Thermometer, 2-1/2" Dial, 1-3/4" Lead-Free Brass Stem, Range 0-250 deg F/-20-120 deg C, 2% Accuracy, Adjustable, 1/2" NPT Back 

Bimetal thermometers are inexpensive, simple, and durable. As purely mechanical devices, they display only the current temperature on their dial. They can be accurate to about 1% full span.

Advantages of Bimetallic Thermometers Low cost. Easy to install and maintain. Good accuracy up to ± 0.5 %. Wide temperature range. Ability to withstand, if subjected to a higher temperature, which is 1.5 times more than the design temperature, for which, it is manufactured. Not easily broken. Simple and compact instrument. Robust construction.

Anyone older than Generation X can likely remember peering at the liquid in a glass tube thermometer, or even the dial on a bimetal thermometer, and trying to determine which hashmark the measurement was closest to. Sophisticated industrial and scientific processes have come to depend upon very accurate temperature measurements.

Definition: The bimetallic thermometer uses the bimetallic strip which converts the temperature into the mechanical displacement. The working of the bimetallic strip depends on the thermal expansion property of the metal. The thermal expansion is the tendency of metal in which the volume of metal changes with the variation in temperature.

Some Models in Stock Starting at $55.31 304 stainless steel construction, 0 up to 550°F temperature ranges available, ±1.0% full scale accuracy . Starting at $565.51

Unfortunately, there is no single answer to this question as it depends on various factors such as the specific type of thermometer and what you intend to use it for. However, in general, most bimetallic stemmed or digital thermometers should be calibrated between 32°F and 212°F (0°C and 100°C). Video Player is loading.

Bimetal thermometer is a kind of field instrument for measuring medium and low temperature. Bimetal thermometer can directly measure the temperature of 

Bimetallic thermometer calibration The most accurate method for calibrating the bimetallic thermometer is the ice point method. To calibrate a bimetallic thermometer using this method, fill a glass completely with ice, add cold water, and let it sit for 4 to 5 minutes. Next, insert the stem of the thermometer into the ice water.
