金属或陶瓷套管垂直热电偶
 |
|
Base metal thermocouple assemblies are designed
to be used in the most severe and demanding environments. The choice
of a specific style is to a large degree determined by the temperature
working range, ambient atmospheric or media conditions, as well
as the size and shape required for the application. Control requirements
such as accuracy and speed of response may also be considerations.
When speed of response is critical, specify the
open end construction. An exposed element is directly subject to
corrosion and physical damage; therefore, this style should be used
only after consideration of the relative need for fast response
versus thermocouple life.
|
|
Another feature for improving response time is the
butt welded junction. This design has less mass and therefore faster
response that the twist, which is normally supplied by the factory.
The twist weld offers greater mechanical strength and longer life.
When possible, the sensor should be installed in
a vertical plane rather than horizontal to prevent sagging.

This sensor offers the same functionality and features
as the 90° elbow style described on the previous pages, except it
is not offered with a ceramic tube or a nickel tube.

Offers the same functionality and features as other
industrial sensors described on previous pages, except will accommodate
wire only down to 14 gauge.
For high performance and added flexibility, we suggest
you consider our BARCOPAC® MgO insulated thermocouples.

This thermocouple can be mounted to the process
with compression attaching device.

Elements are constructed of high quality material
using modern techniques to construct the hot junction. Other high
quality components are designed to meet rugged requirements. Mullite
protection pipes are impervious to gases at high temperature. They
have good resistance to thermal shock but poor resistance to mechanical
shock; they should be mounted vertically.
Aluminum oxide protection tubes have fair resistance
to thermal shock and mechanical shock. They are impervious to gases
up to 3200°F.
|
|
Primary metal industry, heat treat furnaces, forging
furnaces and bright annealing. Suitable for ceramics and glass industries.
Semi-conductor manufacturing and research laboratories.

This thermocouple is assembled with two tubes to
assure element protection in the event one of the tubes cracks or
breaks. Also, two tubes provide additional mechanical strength.
Mullite protection tubes are impervious to gases
at high temperature. They have good resistance to thermal shock
but poor resistance to mechanical shock; they should be mounted
vertically.
3/8” o.d. primary tube is inside 11/16” o.d. outer
tube; 11/16” o.d. primary tube is inside 1” o.d. outer tube.

贵金属双套管(陶瓷套Inconel
601)垂直热电偶
|
|
Elements are made of top quality material. Insulators
are 99.7% Al2O3 (high purity). Primary protection tube is ether
high temperature Mullite or aluminum oxide. The secondary protection
tube is Inconel 601 which has a high resistance to thermal and mechanical
shock up to 2300°F. The Inconel 601 protection tube has excellent
resistance to oxidation up to 2300°F and to corrosion at high temperature.
Hydrogen makes it brittle.
3/8” o.d. primary tube is inside an 0.8450” o.d.
pipe; 11/16” o.d. tube is inside a 1.050” o.d. pipe.
|
|
For use in furnaces, kilns, and other locations
where the protection tube is subject to either mechanical or thermal
shock. Suitable for high temperature heat treating, carburizing,
nitriding, salt baths, blast furnace operation, gas generators,
and ceramic kilns.

贵金属双或三套管(陶瓷套金刚砂)垂直热电偶
|
|
The design of this assembly is for the maximum protection
of the noble metal element. The primary protection tube (or tubes)
protects the element from outside gases while the outer tube of
silicon carbide protects the assembly against the cutting action
of flames and hot gases. You can choose either high temperature
Mullite or aluminum oxide for the primary tube material. High temperature
Mullite is not recommended for temperatures above 1800°F.
|
|
Industrial Silicon carbide protection tubes have
low lag time and long life; high resistance to thermal shock, high
conductivity, and impermeability. They are especially resistant
to many corrosive atmospheres and are highly resistant to attack
by many molten nonferrous metals.
For use with molten nonferrous metals, brick kilns,
ceramic kilns and where the thermocouple is exposed to either flames
or hot gases.

This thermocouple is suggested for pickling baths,
and chemical and acid vats. It consists of a 20 gauge element inside
.188” o.d. Teflon FEP coated tube. Teflon FEP is resistant to most
acids and bases, dry fluorine at 300°F, molten sodium hydroxide,
and steam up to 450°F. Among the organics, nearly complete resistance
is shown to aliphatics, aromatics, alcohol, acids, and chlorinated
solvents.

This assembly is particularly
suited to measuring temperature of asphalt and other granular materials
such as grain, sand, gravel, and pulverized coal. The element is solid
14 gauge with porcelain insulation inside a 1/4” NPT seamless steel
case hardened protection pipe. The end of the pipe is cut at an angle
to protect the element and allow close contact with the material.
The tip of the thermocouple with grounded junction style is welded
to the end of the pipe for greater sensitivity. |

铂热电阻(RTD)
|
|
RTDs change resistance with temperature changes.
They are more accurate than thermocouples, especially over a narrow
range. Standard accuracy ratings of 0.25% and 0.10% are offered.
However, they offer less resistance to physical shock, and respond
slower.
The RTD element is a wire coil precision wound to
a specific resistance value, hermetically sealed to prevent influence
from moisture. It is mounted in the tip of a metal protection tube
for physical protection
