Thermocouple Temperature Sensors TMS Europe are a manufacturer of thermocouple temperature sensors that are used in a wide range of industries and applications around the world. Due to the simplicity of the design, simply two wires joined together, thermocouples are suitable in processes where shock and vibration are present. It is mandatory to procure user consent prior to running these cookies on your website. In the simplest form, this could mean just a bare wire design or the junction can be constructed so that it extends out the end of a protection sheath. Exposed junctions give the fastest response time of any thermocouple construction but are only suitable for unpressurised, dry and non-corrosive applications. For example, Type T with its Copper leg has a max temperature of 370C or 700F. Considering the temperature range, the chemical resistance of the thermocouple metals, and overall vibration and abrasion resistance can help when selecting a thermocouple. £29.99 New. That is, a very thin thermocouple may not reach the full temperature range. An exposed junction is where the two wires that make the junction are left without an external protection sheath. K Type Thermocouples are known as general purpose thermocouple due to its low cost and temperature range. Thermocouples have high temperature sensitivity. These can also be utilized in inert or oxidizing atmospheres, however these must not be used in the sulfurous atmospheres, lower oxygen or vacuums for avoiding dangers. Description: Thermocouple: K-Type Temperature Range: -50 to 300¡ãC Probe Length: Approx. Displays up to 8 channels at a time. The magnitude of the voltage depends on the types of wire being used.
