Choosing a Thermometer

When selecting a thermometer, you need to consider a variety of factors. The temperature range your thermometer will need to measure and the medium used in your process are first up. Next, you need to consider the accuracy of the thermometer, as well as the safety and health requirements of your facility. Finally, you should think about the cost of the thermometer, along with the physical space you have to use it in, and your system's connection types. Different thermometers have differing sensing elements, which show the process temperature. Several types are listed below:

• Spirit-Filled Tubes

This is the most simple type of device, which comes with our industrial and sub thermometers. As the medium is heated or cooled, the spirit within the tube rises in a linear fashion, while the dial displays the corresponding temperature.

• Gas-Actuated Thermometers

These thermometers contain a known amount of a particular type of gas, which is contained within a bulb chamber and capillary. As the gas expands or contracts, it pushes a pointer, which in turn indicates the temperature.

• Bimetallic Elements

This type of device is in fact two separate metal strips that are connected and spiraled within the thermometer case. As the medium is cooled or heated, the metals expand at different rates, which causes the strip to coil or uncoil, moving a pointer that indicates the temperature.

• Electronic Thermometers, Thermocouples, and Resistance Temperature Detectors (RTDs)

These devices all work through a metal's resistance and conductivity to produce a signal, which can then be interpreted as a temperature reading.

Industrial Thermometers

This type of thermometer is typically used in HVAC applications. It features a spirit-filled tubed element, and a black molded ABS case with a glass front to prevent dirt and dust from entering the device, as a standard feature. An aluminum case and plastic face are options that may be added for an additional charge.

This thermometer includes only two screws, which permits the case to be rotated 180 degrees, and for the stem to be positioned in 10-degree increments, allowing you to select your preferred viewing position. The lens front, blue liquid-filled thermometer tube is mounted on a V-shaped aluminum scale, which features bold black lines and numerals for ease of reading. It is calibrated against standards that are traceable to the National Institute of Standards and Technology, and is guaranteed to be accurate to ± one scale division.

Bimetal Thermometers

Our bimetal thermometer uses a bimetallic sensing element and may be utilized in a wide variety of applications. Dials are available in sizes ranging from 1" to 5" and connections can be below, on the back, or adjustable on the back, according to your requirements.

This thermometer is constructed from 300 series stainless steel. It features a hermetic seal, which prevents damage to internal parts from moisture and lens fogging. It is manufactured to ASME B40.1 Grade A standards, and, as such, provides 1% full-scale accuracy.

Submarine Thermometers

Appropriate for a variety of HVAC applications, this thermometer includes a spirit-filled, tubed element. It features a 5" aluminum scale with black figures. It comes with a glass lens, a blue liquid-filled tube, and a gray ABS case. Our submarine thermometer is available with 2" nominal stem length for a 3 1/4" OA thermowell or 4" nominal stem length for a 5 1/4" OA thermowell.
