What
is a thermocouple? |
|
What kind of
thermocouples are used? |
| |
How
should we choose a thermocouple? |
| |
What is cold
junction compensation? |
| |
Why
are extension wires used? |
|
What is a thermocouple
with a thermo-well? |
|
How does M-System
provide cold junction compensation in its thermocouple transmitter? |
| |
What is burn-out
thermocouple? |
|
We
need to connect a recorder and a thermocouple transmitter in parallel
with the extension wires from a thermocouple. Is there any problem
in the connection? |
|
How can we
obtain a linearized signal from a thermocouple? |
|
What precaution
should we use when installing extension wire between a thermocouple
and a thermocouple transmitter? |
| |
The
distance between a thermocouple in the field and the control panel
is as long as 100 meters (300 ft). Is there any way to eliminate
the long extension wires? |
|
Which thermocouple
transmitter do you recommend to accurately measure temperature in
such narrow ranges as 0 to 50°C (32 to 122°F)? |
|
How can we
display the maximum and the minimum temperatures measured with a
thermocouple transmitter? |
| |
How
can we generate alarm signals when the difference between two
temperatures exceed the limit? We need alarms for the plus and
the minus deviation, separately. |
| |
How can we
generate alarm signals when a measured temperature is beyond the
set point. |
| |
What is a process
diagram of a typical temperature control system for a furnace? |
|
How can we
protect a thermocouple from lightning? |
| |
All
M-System Thermocouple Input Temperature Transmitters are "married"
to their respective plug-in bases and can not be indiscriminately
moved from base to base. |

To
manage a vinyl house efficiently, I want to monitor the room temperature
as well as the temperature difference from the outside temperature.
How can I realize the flowing two functions? A: indicating the
room temperature. B: providing an alarm signal when the temperature
difference exceeds a preset value. the temperature detection sensor
is RTD. |
| |
We
have a project to measure the temperature of a deep well about
1000 meters under the ground with Pt100 ohms, resistance temperature
detector. Do you have any idea on this? |
|
I
am measuring motor temperature. An RTD is connected to the motor
and I like to transmit the data to a PLC located off site over
the Modbus communication. A PLC may be used to control the load
to the motor or to shut down the motor as needed to prevent burnout. |

We
are planning to measure temperature of an electric furnace with
termocouplein our laboratory. Since we do a lot of experiments,
we have to change thermocouple types and temperature ranges from
time to time. How we can reduce our stock of transmitters to suit
our purpose. |
| |
To
monitor the temperature in incinerator, we are thinking of using
a thermocouple sensor to send 4-20mA signals to control room.
Meanwhile, we also need an alarm device at field in case the temperature
goes out of range. What can you propose for this application? |
| |
We
are looking for a differential RTD transmitter in order to measure
a temperature difference between 2 rooms. And displaying it on
indicator as voltage scaling, -5 to +5V DC.
We know M-System has a differential RTD transmitter, the DR/DRS
but it can accept just 2-wire RTD signals. Does M-System have
this kind of transmitter that can accept 3-wire RTD signals? |
|
We
work for an incineration plant.
Using a heat exchanger, waste heat is reused for an air conditioning
energy in the facility. How can we monitor the temperature difference
between the hot air in and the cooled air out of a heat exchanger? |
