Meaning
P
Peak value display
Displays the maximum pressure reached up to that moment.
Piping-port size
The size of the port on the switch body with which a device can be connected.
PNP (open collector) output
The switch output that uses the PNP transistor for output.
Power saving mode
The condition in which the display is turned off to reduce current consumption.
Pressure-sensing part
The pressure-detecting part of a pressure-detecting element.
Pressure setting
The setting of pressure to determine the point at which the Pressure switch
turns on and off.
Proof pressure
The pressure beyond which the Pressure switch will be damaged.
R
Rated pressure range
The pressure range in which the Pressure switch meets the specifications.
Values outside of this range can be set if they are within the set pressure
range, but cannot be guaranteed to meet the product specifications.
R.D.
The value currently displayed.
For example, when the displayed value is 1.000,
5%R.D. will be
0.05,
which is
5% of 1.000, while for a displayed value of 0.800 it will be 0.04.
Repeatability
Reproducibility of the displayed value for pressure and ON-OFF output
operating point when the pressure changes.
Residual voltage
The difference between the ideal ON voltage and the actual voltage when the
switch output is on. It depends on the load current and ideally should be "0".
Resolution
Refer to "Indication resolution".
Reversed output
The switch output operation in which the switch is turned on when pressure
equal to or less than the set value is detected. In the (hysteresis mode) window
comparator mode, it indicates the operation in which a switch is turned on
when pressure is outside the switch output range (n1L to n1H or n2L to n2H).
(Refer to "List of output modes" on page
27
.)
Ripple
A type of chattering.
S
Setting of function
Refer to "Function selection mode".
Setting pressure range
The pressure range within which the switch output can be set.
Slave Pressure switch
A Pressure switch whose settings are copied to when using the copy function.
Switch output
Alternatively called "ON-OFF output".
U
Units selection function
Function to change the unit in which the value of pressure is displayed. Only a
product with this function can change the unit. A product with Units selection
function cannot be purchased if it is used within Japan. Pressure is indicated
only by SI units in Japan.
W
Wetted part
(or part exposed to fluid)
The part of the Pressure switch which is in contact with the detected fluid, such
as a pressure sensor, seal, or fitting.
Window comparator mode
An output type which holds the output when the pressure is within a certain
range. (Refer to "List of output modes" on page
27
.)
Withstand voltage
The ability to withstand a voltage applied between an electrical circuit and the
body. If more voltage is applied to the product, the product may be damaged.
(voltage mentioned here is not power voltage to activate the product).
Z
Zero clear function
The function which can adjust the displayed pressure value to "0".
