Terms Meaning
Power saving mode
The condition in which the indicated value turns off and current consumption is
reduced.
Pressure-sensing part A 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.
P
Proof pressure The pressure beyond which the Pressure switch breaks.
Rated pressure range
The pressure range in which the Pressure switch satisfies the specifications.
Values over this range can be set if they are within the set pressure range, but
cannot assured the specifications to be satisfied.
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 at a temperature of 25
o
C.
Residual voltage
The difference between the ideal ON voltage and the actual voltage when the
switch output is on. It depends on present load current and ideally should be
"0".
Resolution See "Indication resolution".
Response time
The elapsed time until the ON-OFF output begins working since the pressure
supplied for the Pressure switch has reached the set value. Generally, the
shorter response time is, the better the performance is.
Reversed output
One of the switch output types, and means the operation in which a switch is
turned on when pressure equal to the switch output set value or less is
detected. In the (hysteresis mode) window comparator mode, it indicates the
operation in which a switch is turned on when pressure outside the switch
output range (n1L to n1H or n2L to n2H) is detected.
(Refer to "List of output mode" on page 29.)
R
Ripple A type of chattering.
Setting of function See "Function selection mode".
Setting pressure range The pressure range within which switch output can be set.
Slave Pressure switch A Pressure switch whose settings are copied when using the copy function.
S
Switch output Alternatively called "ON-OFF output".
U
Unit conversion function
Function to change the unit in which the value of pressure is indicated. Only a
product with this function can change the unit. A product with unit-changing
function cannot be purchased if it is used within Japan. Pressure is indicated
only by SI units in Japan.
Wetted part
(or part exposed to gas) That part of the Pressure switch which is in contact with detected fluid such as
a pressure sensor, seal, and fitting.
Window comparator mode
An output type that holds the output when the pressure is within a certain
range. (Refer to "List of output mode" on page 29.)
W
Withstand voltage
Durability to voltage applied between an electric circuit and a body. A product's
durability in withstanding voltage. If more voltage is applied to the product, the
product may be broken. (Voltage mentioned here is not power voltage to
activate the product.)
Z
Zero clear (function) Adjusts the displayed pressure value to "0".
