The Omega Engineering EXPP-J-20-1000 is an exposed junction J-type thermocouple probe designed for rapid and accurate temperature measurements. The exposed junction allows for direct contact with the measured medium, providing a fast response time. The J-type thermocouple is commonly used in a wide range of industrial and laboratory applications due to its wide temperature range and good sensitivity. The probe has a 20 inch long stainless steel sheath, and the 1000 likely refers to the length of the lead wires (1000 inches).

Applications:

• Surface temperature measurement: Measuring the temperature of solid surfaces, such as metal plates or plastic molds.
• Air temperature measurement: Monitoring the temperature of air in HVAC systems, ovens, and other environments.
• Liquid temperature measurement: Measuring the temperature of liquids in tanks, pipes, and other containers.
• Process control: Monitoring and controlling temperature in industrial processes.
• Laboratory experiments: Measuring temperature in various scientific experiments.

Features:

• Exposed junction: Provides direct contact with the measured medium for fast response.

Additional Details:

The EXPP-J-20-1000 thermocouple probe consists of two dissimilar metal wires (iron and constantan) joined at the sensing junction. The voltage generated at the junction is proportional to the temperature difference between the junction and a reference temperature. The probe's stainless steel sheath provides protection from corrosion and abrasion.

When using this thermocouple probe, it is important to connect it to a compatible thermocouple meter or controller. The meter must be calibrated for J-type thermocouples to ensure accurate readings. The exposed junction should be kept clean and free from contaminants to maintain optimal performance.
