Mineral Insulated Thermocouple And Terminal Block Assembly

Product  Description:

Industrial thermocouple assemblies are used in the process and power industries where thermocouples are installed in pipe lines or vessels. This type of assembly consists of three basic parts, the connection head, sensing element and thermowell or protection tube. Selecting the proper assembly involves consideration of several factors including process temperature, environment, fluid or gas pressure, pipe or vessel size and flow velocity.

Specification:

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 assembly can be supplied with or without a transmitter. Transmitters convert the millivolt input from the thermocouple to a linear analogue or digital output (commonly 4-20 mA). This signal reduces potential inaccuracies in the circuit and negates the requirement for thermocouple extension wire.
3. The assembly has electrical approvals for explosion proof hazardous locations, intrinsic safety, ingress protection and general purpose areas.
4. 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.
Thermocouple diameters range from 0.125 inch to 0.250 inch and 2 mm to 8 mm. Standard diameters are 0.125 inch & 0.250 inch also 3 mm & 6 mm.
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.
