Thermocouples are used in a variety of applications and as safety measures as well. It is important to have a good quality thermocouple manufacturer that provides a large selection to get the right product for each and every application. When you’re in the market to measure the temperature of a liquid, you’re most likely going to be purchasing a thermocouple. The most typical approach to measuring a liquid material temperature is to use an immersion thermocouple, either a single-use or multi-use model. In this brief article, we will discuss some critical points that should help you or your team decide which thermocouple or temperature sensor to purchase and which thermocouple manufacturer is right for your application.
Get Familiar with Your Thermocouple
When two wires made of different metals are brought together at an electrical junction, a voltage is produced due to the Seebeck effect. This measured voltage will help determine the temperature of an object using a thermocouple. The working principle here is that when the temperature of the hot weld differs from that of the reference welds, an electrical voltage is obtained.
Thermocouples for applications involving liquid materials are commonly constructed as interchangeable tips on the end of a long pole. This construction method is used regardless of the material’s composition or properties. After that, the lance is used to securely place the thermocouple in preparation for immersion into the liquid bath.
An exact temperature readout can be obtained using thermocouple sensors over various temperature ranges. Thermocouples and modern pyrometer equipment can provide an accuracy of +-2F degrees (based on the specifications of the thermocouple manufacturer) within the operating range of most liquids, typically more than adequate for multiple applications.
Learn the Type of Thermocouple You Need
Another benefit of thermocouples is the availability of multiple types. They may be selected as per the temperature range to be measured and the conditions of the surrounding environment.
Rama Corporation offers many stocked thermocouple options. These can range in size, shape, and material selection, making it an easy choice to quickly find something that fits your needs.
We carry a variety of 9 different thermocouples, and their names correlate to letters of the alphabet. When picking out a temperature sensor from your thermocouple manufacturer, the temperature range is, by far, the most crucial consideration. While selecting the ideal thermocouple, the range should be your primary point of reference. It includes temperatures as low as minus two digits and as high as hundreds of degrees Fahrenheit.
Thermocouple Response Time
When choosing a temperature sensor from your thermocouple manufacturer, response time is another issue. Response time represents the amount of time that must pass before an accurate measurement can be obtained. A thermocouple’s response time is mainly determined by the material utilized in its manufacture as well as the thermal mass of the thermocouple probe after it is complete. E.g., it will take more time to achieve a steady reading with more mass.
Pricing and Customization Options
Most thermocouple manufacturers can guide not just the kind of thermocouple to use but also the additional product characteristics and materials most appropriate for a specific application.
Many thermocouple manufacturers suggest using simple multi-dip tips for smaller crucibles and situations where no slag is present. These tips are high precision, non-splash probes appropriate for furnaces with no surface slag. Plus, these reasonably priced tips provide precise temperature readings in a short time. Since the quartz tube is submerged in the molten material, an insulating sleeve is not required for this thermocouple, in contrast to bigger multi-use thermocouples.
On the other hand, the thermocouple probe may need an insulating sleeve to get an accurate reading from a more oversized furnace or ladle. It is because the probe has to penetrate surface slag. While the probe is being plunged through the hot slag layer, the protective insulation available in various lengths can shield the lance and the thermocouple contact socket from the extreme heat.
