AKCP TCXX Thermocouple Sensor

The AKCess Pro thermocouple is perfect for use in heavy industries, such as petrochemical and metal processing. With an ability to measure from -200ºC (-328ºF) up to 800ºC (1472ºF) it is also suited to those low temperatures found in cryogenics and medical applications.

• Available in both J and K type thermocouple
• For use with the J or K type thermocouple adapter
• Works with securityProbe series only
• Wide temperature range for use in a variety of industrial applications
• Powered by securityProbe, no additional power necessary

Different thermocouple types (e.g. K, T, N, J, etc) are made from di.erent combinations of metals. For example, a J Type is made from Iron and another slightly di.erent copper-nickel alloy and the K Type thermocouple has a Nickel-Chromium positive conductor and a Nickel-Aluminum negative conductor.

The AKCP J and K Type thermocouple adapters are specially designed for not only connecting the AKCP K Type Thermocouple temperature sensor to the securityProbe and securityProbe 5E base units, but also allow you to integrate other J and K Type thermocouple sensors into these base units.

When the AKCP Thermocouple sensor, or any other J or K type sensor is plugged into either type adapter and the RJ-45 LAN.


Thermocouple Sensors Explained

A thermocouple is a temperature measuring device consisting of two conductors of dissimilar metals or alloys that are connected only at the ends. When the ends are at di.erent temperatures, a small voltage is produced in the wire that can be related directly to the temperature di.erence between the ends. If the temperature at one end is known, the temperature at the other end can be determined.

Thermocouple wire or extension grade wire is used to connect the thermocouple to the sensing or control instrumentation. The conditions of measurement determine the type of thermocouple wire and insulation to be used. Temperature range, environment, insulation requirements, response, and service life should be considered when selecting a wire type. Di.erent thermocouple types (e.g. K, T, N, J, etc) are made from di.erent combinations of metals. There are two common types of thermocouple wire, Type J and Type K. The J Type is made from Iron and another slightly di.erent copper-nickel alloy and the K Type thermocouple has a Nickel-Chromium positive conductor and a Nickel-Aluminum negative conductor.

Which Thermosensor should be used?

Di.erent thermocouple types (e.g. K, T, N, J, etc) are made from di.erent combinations of metals. There are two common types of thermocouple wire, Type J and Type K. The J Type is made from Iron and another slightly di.erent copper-nickel alloy and the K Type thermocouple has a Nickel-Chromium positive conductor and a Nickel-Aluminum negative conductor.

Type K thermocouples are used in oxidizing, inert or dry reducing atmospheres. Exposure to vacuum is limited to short time periods. Must be protected from sulfurous and marginally oxidizing atmospheres. Reliable and accurate at high temperatures.

The AKCP J and K Type thermocouple temperature sensors can be connected to the securityProbe and securityProbe 5E base units, and can also let you integrate other J and K Type thermocouple sensors into these base units using the AKCP thermocouple adaptors. When the AKCP Thermocouple sensor or any other J or K type sensor is plugged into either type adaptor and the RJ-45 LAN cable is connected to the Intelligent Sensor port on the securityProbe base unit or the E-sensor8 expansion module, the base unit will auto detect the sensor. A built-in graph option is included on all securityProbes for graphing temperature variations over a period of time.

K type thermocouple

The K type thermocouple is the most commonly found and used thermocouple type. The tip is made from a +ve electrode of chromel and a -ve electrode of alumel metal. It is less sensitive than the J type thermocouple but has a wider temperature range.

200ºC to +900ºC

J type thermocouple

The J type thermocouple has a +ve electrode of Iron and a -ve electrode of constantan metal (a copper-nickle alloy). It has a lower range than the J type thermocouple but a higher sensitivity.

200ºC to +750ºC

With the securityProbes autosense function the sensor is automatically detected and configured when plugged in. Setup is quick and easy, with the user only needing to setup the thresholds required for high and low warning/critical levels and any notifications required. This is simply done using securityProbes web based interface. No calibration is required
