a thermocouple sensor should have the following characteristics answers

The Basics of Thermocouples Circuit Cellar

· These ICs have a temperature sensor in them that detects the temperature of the cold junction. This is presumably the same temperature as the circuit board on which the IC is mounted. The IC then produces a voltage that is proportional to the voltage produced by a thermocouple with its hot junction at ambient and its cold junction at 0°C. This voltage is added to the EMF produced by the ...

· Aside from the mechanical characteristics, we have thermal characteristics. A <1mm probe will minimally affect the material being measured. A small thermocouple will have a very fast response time so there will be not much lag between a change in temperature and the resulting electrical signal. The LM35 being huge and encased in plastic, will be very sluggish in comparison. So the …

Thermocouples | Electrical Instrumentation Signals ...

The answer is this: because the other forms of temperature measurement used for reference junction compensation are not as robust or versatile as a thermocouple junction, but do the job of measuring room temperature at the reference junction site quite well. For example, the thermocouple measurement junction may be inserted into the 1800 degree (F) flue of a foundry holding furnace, while the ...

Thermocouple | JUMO Automation

In the following table: Properties of Thermocouples the different elements are listed together with a short characterization. The recommended maximum temperatures can only be assumed as basic values, as they depend strongly on the application conditions. They refer to a wire diameter of 3 mm for the base and mm for the noble elements.

· I really suggest you give this a read Thermocouple Response Times and become familiar with thermocouples and their characteristics as well as uncertainties. Finally larger thermocouples made with heavier gauge wire will have even slower response times. You have not defined temperatures or temperature change, other than K you have not defined your Type K thermocouple.

Thermocouple Characteristics | Ceramic Protecting Tubes

Maximum operating temperature of 2900° F (1600° C). Impervious to air to 3000° F, to dry hydrogen and carbon monoxide to 2550° F. Low rate of thermal expansion ( x 106/° F) enhances thermal shock resistance. Resistance to acid slag is good. Basic slag is fair. Recommended for J, K, N, and E type thermocouples.

A Basic Guide to Thermocouple Measurements

Thermocouples are common temperature sensors used in a wide variety of commercial and industrial applications. While slightly less accurate than resistance temperature detectors (RTDs), thermocouples cover a wide temperature range, are selfpowered, and have a fast response time. Their simple construction make them inexpensive and durable. Because of the small sensor voltage and low noise ...

· Answer : You have to consider the characteristics and costs of the various sensors as well as the available instrumentation. In addition, Thermocouples generally can measure temperatures over wide temperature ranges, inexpensively, and are very rugged, but they are not as accurate or stable as RTD’s and thermistors. RTD’s are stable and have a fairly wide temperature range, but are not as rugged and inexpensive as thermocouples. …
