About Silver Instrument J type thermocouple Sensor

A thermocouple is an electrical device used as a sensor for temperature measurement. This device senses low to high temperatures in the form of voltage changes and displays the temperature digitally by calculating the voltage changes. It was discovered in 1821 by Thomas Seeback and thus have been serving the function since then. The self-powered thermocouple can measure temperature between -300 and 4000F.

However, this range varies according to different types of thermocouple. The advanced digital thermocouple comes up in different styles. This styling varies from simple wires to thermocouple with probes and beaded wire thermocouple. Thermocouple differs from other temperature sensing devices in their constituency and applications. They are used mostly for high-temperature measurements in industries whereas other sensors like a thermometer are rarely used commercially.

Description Of J type thermocouple Sensor

Type J thermocouple is also a subtype of base metal thermocouple with iron-constantan as its constituents, is also a cheap metal thermocouple. This thermocouple also has great accuracy and reliability almost equal to K type thermocouple but the temperature range and life span are much shorter than the K type thermocouple. This limits its use to a certain level but j type is still 2nd most commonly used thermocouple due to low price.

The temperature range is between -200 ~ 1200 ?, but the normally used temperature range is usually 0 ~ 750 ?,J thermocouple whereas the accuracy and risk factor are exactly the same as for K type thermocouples i.e 75% and 0.4% respectively. J type thermocouples are not ideal for use in a damp environment since they are less resistance to oxidization.J thermocouple is easy to identity because the cables has a specific black coding colour.
