| 032058 | We are planning to input
the signal from a level sensor at field to DCS of which 4-20mAdc input is
required. We chose M-System's current loop supply (model YVD). 3-wire conncetion
is required in the level sensor, however, the YVD is for 2-wire sensor connection
as far as I check in the specification sheet. Do you have any current loop
supply unit to meet 3-wire type level sensor. Or can I used the YVD for
the sensor? [ HTML ] [ MS Word  96k ] |
| 032059 | In order to supply power to two-wire transmitter,
we are planning to use your current loop supply (model DS-24). The output
1 will be provided to a recorder, and the output 2 to a computer. As far
as I looked over its specification sheet, we could not find any description
of load resistance for each output. [ HTML ] [ MS Word 108k ] |
| 032064 | We are planning to measure
the temperature of brick making furnace with thermocouple. In ordinary case
we check it in the control room, 200 meters far from the furnace. We also
want to check it at the furnace site but we do not have a power for instrumentation
equipment there. Do you have any good idea? [ HTML ] [ MS Word 96k ] |
| 032074 | We have a two-wire type flow meter. The signal
from this flow meter needs to be displayed on a bar graph indicator (1-5
VDC). Meanwhile, this signal also needs to be converted to 4-20mA DC and
feed into a PLC. What is the most efficient way to achieve this? [ HTML ] [ MS Word 132k ] |
| 032096 | We monitor water well level
at the site. We have used two types level transmitters, one is measuring
0-10 meters proportional to its output 4-20 mAdc, the other is measuring
0-3 meters proportional to its output 4-20 mAdc.We are going to prepare
one level transmitter and one current loop supply as spare parts.Does M-System
have the current loop supply, which can adjust the output span of 4-20 mAdc
widely when measuring 0 - 3 meter with using 0 - 10 meter measuring type
level transmitter? [ HTML ] [ MS Word 76k ] |
| 032102 | We usually use the Current Loop Supply model
M2DY or M2DYS when 24 V power supply is required for 2-wire type field sensor.
In a recent application, we need to use a 3-wire type field sensor and its
current comsumption is 24V / 100mA. Does M-System have a suitable unit?
Please let me know how we should connect the device with the 3-wire field
sensor? [ HTML ] [ MS Word 273k ] |
| 032108 | We are utilizing a 2-wire flow rate transmitter
and a current loop supply, M2DYS as combination. This time we’d like
to add a 2-wire digital DC meter, model 6DV-B inserted on this loop. However,
the output load resistance of the flow rate transmitter will exceed the
limited 400 ohms if we installed the 6DV-B in series connection. Does M-System
have some suitable solution? [ HTML ] [ MS Word 128k ] |
| 032124 | We use a 2-wire flow meter at field. We have some problems recently. Even the flow volume is zero, the indicator on the receiving instrument shows fluctuation and unstable. Do you have any solution with any M-System transmitter? Furthermore, the flow meter doesn’t have square root extraction function, so please introduce a suitable transmitter with square root extractor. [ HTML ] [ MS Word 92k ] |
