※There is no short-circuit protection in analog voltage output. Do not connect this output to power supply or capacitive load directly.
※Please observe input impedance of connected equipment when use analog voltage output.
And be sure to check voltage drop caused by resistance of extended wire.
※If short-circuit the control output terminal or supply current over the rated specification, control signal is abnormal due to

PSA / PSB Series
Functions (PSA/PSB)
Pressure unit change
PS -V01 (C) (P)/PS -C01 (C) (P) has 7 kinds of pressure
unit and PS -01 (C) (P)/PS -1 (C) (P) has 4 kinds of
pressure unit.
Please select the proper unit for application.
• PS -V01 (C) (P), PS -C01 (C) (P) :
kPa, kgf/cm², bar, psi, mmHg, inHg, mmH₂O
• PS -01 (C) (P), PS -1 (C) (P) : kPa, kgf/cm², bar, psi
※When using mmH₂O multiply the display value by 100.
Output mode change
There are 6 kinds of control output modes in order to
provide the various detection. Select a mode for your proper
application.
• Hysteresis mode [ F-1]
When variable hysteresis is required for pressure detection.
• Automatic sensitivity setting mode [ F-2]
When it is required to set detecting sensitivity automatically
at proper position.
• Independent 2 output mode [ F-3, F-4, F-5]
When it is required to detect pressure from two position
with one product.
• Window comparison output mode [ F-6]
When is required to detect pressure in a certain range.

Installation (PSA Series)
1. When installing pressure port, it is able to bring pressure
from 3 directions by changing the mounting direction of
the pressure port.
2. Basic spec of pressure port is Rc1/8 and option pressure
port is NPT1/8. Use general one-touch fitting.
Response time change
(chattering prevention)
It can prevent chattering of control output by changing
response time. It is able to set 4 kinds of response time (2.5,
5, 100, 500ms) and if the response is getting longer, the
sensing will be more stable by increasing the number of
digital filter.
Analog output scale setting
It is not fixed the analog output (1-5VDC) scale as the rated
pressure range but this is a function to change properly
for user's application. When the position[A-1] for 1VDC
output and the position [A-5] for 5VDC output are set, the
pressure range of A-1 to A-5 is to 1-5VDC analog output.
3. Please use seal tape at port plug in order to prevent
pressure leak.
4. Please block another two pressure ports not used with
port plug.

Key lock
This unit has 2 kinds of key lock function in order to prevent
wrong operation.
• LOC: All keys are locked, it is impossible to change any
parameter setting/preset, zero point adjustment, peak
hold and bottom hold. (Enable to change EY mode only).
• PaL: It is impossible to change parameter setting/preset,
zero point adjustment. (Enable to check peak hold and
bottom hold, and to change EY mode).
• UNL: All keys are unlocked.

5. Please connect it by using spanner (13mm) at the metal
part in order not to overload on the body when connecting
one touch fitting.
13mm
spanner
Zero-point adjustment
This function is to set the display value of pressure at zero
when port is opened to atmospheric pressure.
Peak hold and bottom hold
This function is diagnosis malfunction of the system caused
by parasitic pressure or to check through memorizing the
max./min. pressure that occurred in the system.

Caution
The tightening torque of one touch fitting should be max.
10N.m. If not, it may cause mechanical problem.

6. PSA Series has 2 kinds
of brackets so it is able
to install it in two different
ways.
7. At first, please unscrew
hexagon wrench bolt and
assemble the bracket
on this unit by fixing the
hexagon wrench bolt.

Caution
In this case, tightening torque of hexagon wrench
should be max. 3N.m. If not, it may cause mechanical

8. Bracket (PSO-01) and front protection cover (PSO-P01)
are sold separately. Please see the pictures for installation.
SENSORS
PSA, PSB Series is for sensing of non corrosive gas.
Do not use this product at corrosive gas or flammable
gas, etc.
• Please using this unit within the range of specification, if
applying pressure is larger than specification, it may not
be working properly due to damage.
• After supplying power, it takes 3 sec. to work.
• When using switching mode power supply, frame ground
(F.G.) terminal of power supply should be grounded.

Pressure port
• It may cause malfunction by noise, when wiring with
power line or high voltage line.
• Do not insert any sharp or pointed object into pressure
port. It may cause mechanical problem due to sensor
damage.
• Do not use this unit with flammable gas, because this is
not an explosion proof structure.
• Be sure that this unit should not be contacted directly with
water, oil, thinner, etc.

2. It is able to use it without the pressure port according to
environment. In this case O-Ring between pressure port
and its body should not be taken out in order to prevent
pressure leak.
