High speed response: 2.5 ms
or less
With anti-chattering function
Stable switch output is possible even with sudden
Anti-chattering function
Devices such as large bore cylinders and high-flow vacuum
ejectors consume a large volume of air when they operate, and
this may cause a momentary drop in the primary pressure. This
function prevents such momentary pressure drops from being
detected as abnormal pressures by allowing the response time
selection to be changed.
[Selectable response times: t]
2.5 ms (normal), 24 ms, 192 ms or 768 ms
The normal setting is selected when shipped from the factory.
(Operating principle)
The pressure values measured within the user-selected response
time are averaged, and switch output (ON/OFF) is determined by
comparing this averaged pressure value with the set pressure.

With auto shift function
Allows switch output unaffected by variations in
primary pressure.
Auto shift function
Erroneous operation may occur if there is fluctuation in the
primary pressure.
The auto shift function compensates for pressure changes to
ensure proper ON/OFF switch response during such fluctuations.
(Operating principle)
At the point when the primary pressure fluctuates, the set
pressure value is compensated by setting the auto shift input
(external input) to low (no-voltage) input, using the pressure
measured at that point as a standard.
Without using auto shift
When the primary pressure fluctuates, a correct determination becomes impossible.
