Range of application: µ series of card-track type
signal insulation and conversion instruments is widely
used in power industry, metallurgical industry, light
industry, chemical industry and glass industry.
Shine’s ? series of card-track type signal insulation
and conversion instruments offers you high precision and
steady solution to signal transmission.
Because of the decentralization of the working temperature
for various elements and devices, it is difficult to solve
the problem of temperature drift for integral meter. And
thus the low precision and large temperature drift have
already influenced the stability during the control process.
Following are the problems brought about by temperature
1. Zero point and measurement range can be adjusted only
when the instrument has been connected to power for ordinary
products by half an hour or even more. Even when these
are finished adjusting the zero point and measurement
range, we still keep wondering whether there is temperature
drift under the environment and temperature change.
2.In order to ensure the quality of our products during
process period, we have to select excellent field instruments.
However, it is so difficult to explain the annoying problems
we usually meet in practice. For example, without relative
insulation and conversion instrument, we cannot effectively
transfer the high precision (0.05-0.1%) transmitter we
buy to the control room. Often we have to make shift with
what is on hand. But the problem of temperature drift
must be solved if we want to raise precision and stability.
Shine initially used temperature field compensation theory
to solve this problem. By greatly improving the influence
of output drift given by the change of the electricity
and the environment temperature on the instrument, the
output of the instrument will be stable after the current
is switched on and then the stable and reliable field
signal transmission is ensured.
