Abbreviation of full span and full scale; difference between the minimum and
maximum rated pressure values. means the maximum fluctuation range of the
pressure switch rated value.
For example, when the rated pressure range is 0 to 1.000 [MPa]:
F.S. = 1.000 - 0 = 1 [MPa]
(Reference: 1%F.S. = 1 x 0.01 = 0.01 [MPa])
A mode in which setting of functions is performed. It is a separate menu from
the switch setting. If any function settings need to be changed from the factory
default, each setting can be selected with "F".
The setting items are: output mode, display color, digital filter, display reverse,
zero cut-off display on/off, display value fine adjustment, use of display OFF
mode, and use of security code.
The difference between ON and OFF points used to prevent chattering.
Hysteresis can be effective in avoiding the effects of pulsation.
Mode where the switch output will turn ON when the measured value is
greater than the set value and will turn OFF when the flow rate falls below the
set value by the amount of hysteresis or more.
Mode where the switch output will turn ON when the flow is greater than the
set value, and will turn OFF when the flow falls below the set value by the
amount of hysteresis or more.
The flow passing per unit of time. If it is 10 L/min, there is a flow of 10 L
passing through the device in 1 minute.
Insulation resistance of the product. The resistance between the electrical
circuit and the case.
The voltage drop across the product (and therefore not applied to the load),
when the switch output is ON.
and ideally should be 0 V.
Function that prevents changes to the settings of the flow switch (disables
button operation).
The maximum voltage that can be connected to the output of an NPN device.
The maximum current that can flow to the output (output line) of the switch
output.
Operating condition in which flow rate, pressure and temperature is detected
and displayed, and the switch function is operating.
Operating condition in which pressure is being detected and displayed, and
the switch function is working.
The flow which is converted into the volume at 0
pressure).
<nor> indicates that the product is in normal condition.
One of the switch output types. In hysteresis mode the switch output is turned
ON when pressure equal to or greater than the switch output set value is
detected. In window comparator mode, the switch output is turned ON when
measured value between the switch output set values (P1L to P1H) is
detected.
