Feature:
1. The sensor can be mounted into a thermowell or directly into a process with the use of a fixed,spring loaded or compression process fitting.
2. The thermocouple sensors available for this assembly are provided with a variety of sheath materials including stainless steels, corrosion resistant and high temperature oxidation resistant alloys.
3. Thermocouple diameters range from 2 mm to 8 mm. Standard diameters are 3 mm & 6 mm.
4. The thermocouple sensor can be springloaded ensuring a positive contact to the base of a thermowell bore.
5. Thermocouple temperature ranges are dependent on the sheath & conductor diameter, element calibration, and sheath material.
6. A variety of neck extensions are possible. They provide a fixture from the enclosure (connection
head) to the process or thermowell. The standard neck extensions are the nipple-union-nipple or
the male threaded neck tube. These extensions allow for directional rotation of the head for field
wiring as well as a positive quick disconnection of the assembly from the process or thermowell.
Application:
The Base Metal Thermocouple Assembly With Metal Protection Tube are designed for use in corrosive or hostile environments. The choice of a specific style is determined by the temperature working range, ambient atmospheric or media conditions and the size and shape required for the application. Control requirements, such as accuracy and speed of response, may also be considerations to take into mind. It is mainly used for below area,
1. Metal processing such as aluminum, zinc, brass (with appropriate protection tube)
2. Chemical Industry
3. Petrochemical Industry
4. Industrial storage tanks
