Accurate temperature measurement is one of the important requirements in various industries. For example, maintaining a certain temperature is necessary in the processing of food and medicine, as well as in various industrial applications. Temperature measurement in these processes is done with a variety of temperature sensors such as RTDs, thermistors, and thermocouples.

These devices are designed to generate electrical signals when the temperature changes. Due to the growing dependence on precision temperature sensors, today you can easily find them on the market from various manufacturers around the world. Therm-x is one of the leading manufacturers of temperature sensors in the United States. Want to know all about these sensors and their benefits in industrial applications? This article will help you understand the same.

Types of temperature sensors provided by Therm-x

Therm-x specializes in the manufacture and supply of a variety of standard and original temperature sensor manufacturers. Customers can benefit from the following temperature probes in standard and non-standard designs.


These devices have wires made from two different metals. The wires are connected to form a hot junction and a cold junction. A hot connection is used for measurement, and a cold connection is usually connected to a measuring device such as a digital display or controller. The device generates a measurement signal based on the difference between the reference and measurement connections.

Therm-x offers mineral insulated thermocouple (MI) thermocouples in which the mating thermocouple wires are surrounded by insulating material. Magnesium oxide is commonly used as an insulating material. These thermocouple sensors are used in harsh environments and can withstand temperatures up to their melting point. MI thermocouples are available in a wide range of diameters and can handle external pressures up to 50,000 psi.

The company offers the following types of thermocouple sensors made of various alloys:

Type E: chromel and constant

Type J: iron and constant

Type K: chromel and alumel

Type N: Nisil and Nicrozil

Type T: copper and constant

Type B: BP / BN

Type C: CP / CN

R / S: RP / RN

Resistance Temperature Detectors (RTDs):

Consist of elemental wires wrapped around a glass or ceramic core. RTDs measure temperature by relating the resistance of an RTD element to temperature. Most RTDs are manufactured from platinum with an accuracy of 0.1 to 1 ° C, allowing for a wide temperature range from -200 ° C to 600 ° C. Therm-x offers resistance thermometers in various tolerances such as Class A, B and 1 / 3 DIN. The company also supplies resistance thermometers in various configurations. More information is available upon request. These RTDs are often used in a variety of industrial applications.


These are temperature-sensitive devices that show a predictable, large and accurate change in resistance as a function of temperature change. Typically NTC thermistors are used to measure temperature. In these devices, resistance increases at low temperatures and vice versa. The change in resistance is quickly reflected in the NTC thermistors and provides high accuracy in the 0.05 to 1.5 ° C range. Thermistors provide efficient operation over the -50 to 250 ° C temperature range. Therm-x offers thermistors with various power resistances.
