I
am looking for a product, which can add two types of flow. Besides,
I need thin unit because there is much room in the existing cabinets. |

How

With model
M2MLS (inputs:1-5V DC, output: 4-20mA), when both inputs 1 and 2
are 0V DC, the M2MLS provides the output greater than 4mA. Why? |

I
want to determine the ratio of air and fuel flow for combustion
control in order to improve the efficiency. |
|
I have two
signals. When one of them multiplied with a certain factor exceeds
another signal, I need an alarm. |
|
I'm
looking for a product that can be used for ratio control of flow
but need to change the ratio frequently. Without using a tester
or a screwdriver, is there any product to match my request? |

I am looking
for a product that can be used for ratio control of air/fuel flows
and I periodically have to change the ratio. Is there any product
to meet my requirement? |

In
my current PID controller setup, when a contact signal changes the
Set Value (SV) in the control loop, the PID process controller responds
with a sudden increase of the manipulated value, causing instability
in the control process. How could it be possible to make any controller
MV responses to SV changes more gradual? |

We have a mixing
machine for adhesives. When the rotating speed of its motor becomes
too high, the motor is heated and turns to dangerous condition.
Can you tell us how to limit the max rotating speed by a remote
signal? |

Due to the
common mode noise problem, we urgently need isolation for the 4-20mA
current loop. But we don't have an isolator right now. And we have
an isolated type High/Low selector as a spare part. Can we use this
unit (M2SES, inputs 4-20mA, output 4-20mA)? |

I have an application
where my input signal to a signal conditioner is constantly rising
and falling. How can I maintain the output from the signal conditioner
so that it will only increase in response for a rising value? |

When measuring
the quantity contained in a storage tan, how can I measure the amount
already used up, rather than the amount presently contained with
in the tank? |

We are measuring
the current of a motor by a signal conditioner via CT (current transformer)
is being measured. This signal (4-20 mA) goes to a telemetering
device to transmit to a control room. But in the event when the
motor is switched on, the signal conditioner outputs more than 20
mA due to a rush current. by that, the signal is recognized as motor
default. |

We use a Math
function Module model JF to measure two tank levels. Today we removed
the unit from its loop and provided a simulation signal 4-20mA DC
to it by using a signal generator as show in Fig.1 to calibrate
it for shutdown maintenance. However, we couldn't get the output
correctly. Why? |

When one of
the three input terminals is open because this input is reserved
for future expansion system, will there be any problem? The equation
is as follows: X0=K0{K1(X1 + A1) + K2(X2 + A2) + K3(X3 + A3)} +
A0 |

Wind speed
is being measured with an anemometer with north as center. Currently
4-20mA DC signal corresponding to wind speed 0-1000 rpm for north
to east direction is indicated on a meter and another 4-20mA DC
signal corresponding to 0-1000 rpm for north to west direction on
another meter. I want to indicate these two signals on a single
meter. |

The customer
is a printing company who is producing LCD color filters and supplying
them to many electronic companies. To keep the color filter’s
good quality, they use a clean room in their factory manufacturing
process. There are 2 (two) pressure sensors in the clean room. Each
sensor’s output is a 4-20mA DC. They want to control the clean
room’s fan inverter system in proportion to the average output
of the 2 (two) pressure sensors. Therefore, they need to get an
average value of two pressure sensors as a 4-20mA DC standard signal.
Does M-System have a suitable adder unit for this application? |

I use an output
signal (1-5 Vdc) from a water level indicator and watch water level
of a tank.
I use a pump and pull out water of a tank, but the tank suffers
from minus number pressure when I operate the pump. It is about
0.3 V fall of output signal,1-5 Vdc. This minus number pressure
troubles us to do a precise measuring of tank level.
Could you suggest how to bias the output signal of 0.3 V when the
pump works? |
