Term
Definition
O
Operating humidity
range
Humidity range in which the product operates normally.
Operating pressure
range
Pressure range in which the product operates normally.
Operating
temperature range
Ambient temperature range in which the product operates normally.
P
Pressure
characteristics
Indicates the change in the control accuracy due to changes in the fluid pressure.
Proof pressure
Pressure limit that if exceeded will result in mechanical and/or electrical damage to the
product.
R
Rated control flow
range
Flow range in which the control accuracy is satisfied.
Repeatability
Reproducibility of the controlled flow rate or analogue output value, when the measured
quantity is repeatedly increased and decreased.
S
Set controlled flow
rate range
Range in which the commanded flow rate can be input.
Settling time
Time for the flow rate to reach within ±3%F.S. of the commanded flow rate value in
relation to the input signal.
For this product, the time when the step signal of 1 → 100% is input is stated in the
specifications.
(Temperature: 25
o
C; pressure: reference operating pressure)
Standard condition
The flow which is converted to the volume at 20
o
C and 1 atm (atmospheric pressure).
[STD] indicates that the product is in standard condition.
Switch output
Output type that has only 2 conditions, ON or OFF. In the ON condition an indicator
LED will show, and any connected load will be powered. In the OFF condition, there will
be no indicator LED and no power supplied to the load. An output showing such
behavior is called switch output.
T
Temperature
characteristics
Indicates the change in the control accuracy due to changes in the ambient
temperature.
U
Units selection
function
A function to select the display units other than the international units (SI units)
specified in the new measurement law in Japan. The product for use in Japan is not
equipped with this function.
W
Wetted part
A part that comes into physical contact with the fluid.
Z
Zero-clear
Function to adjust the flow rate display to zero.
