■NOTE
○Follow the instructions given below when designing, selecting and handling the product.
●The instructions on design and selection (installation, wiring, environment, adjustment,
operation, maintenance, etc.) described below must also be followed.
Product specifications
Use the specified voltage.
Otherwise failure or malfunction can result.
Applicable fluid is a fluid that does not corrode C3604 + electroless nickel plated, AI203 (aluminum
oxide) and FKM.
Do not use a fluid containing chemicals, synthetic oils including organic solvent, salt and corrosive gases.
Otherwise, damage to the product and malfunction can result.
Check the details of the specifications before using.
Reserve a space for maintenance.
Allow sufficient space for maintenance when designing the system.
A ceramic diaphragm type pressure sensor is used in this product. The ceramic diaphragm can be
damaged by overpressure from hydraulic shock, which can be generated when condensate in the fluid
collides with the sensor during pressure fluctuation. This is also known as "water hammer".
To mitigate hydraulic shock, it is recommended to insert an orifice between the fluid and the sensor. A gas pocket
also needs to be between the orifice and the sensor to cushion the shock pulse. The sensor would then need to
be located above the orifice with the orifice mounted vertically so that no fluid gets between the orifice and sensor.
Some recommended and NOT recommended examples are shown in the following figure. Part
numbersZS-31-X175 or X188 are applicable orifices (called throttles in product literature).

●Product handling
Installation
Follow the specified tightening torque.
Excessive tightening torque can break the Pressure Sensor.
Insufficient tightening torque can displace the Pressure Sensor from the original position or loosen the mounting
screws. Refer to the following table for the appropriate torque values.
Nominal size screws
Appropriate tightening torque (Nm)
R1/8
3 to 5
R1/4
8 to 12
When piping, apply a spanner vertically to the piping section for the sensor.
Applying the wrench in other position can break the Pressure Sensor
Be sure to ground terminal FG when using a commercially available switch-mode power supply.
Do not drop, hit or apply shock to the Pressure Sensor.
Otherwise damage to the internal parts can result, causing malfunction.
Do not pull the lead wire forcefully, not lift the product by pulling the lead wire. (Tensileforce 35N or less)
Hold the body when handling to avoid the damage of the Pressure Sensor lead to cause the failure and
malfunction.
For piping of the Pressure Sensor, hold the piping with a spanner on the metal part of the piping
(Piping attachment).
Holding other part with spanner leads to damage the Pressure Sensor.
Eliminate any dust left in the piping by air blow before connecting the piping to the product.
Otherwise it can cause damage or malfunction.
Do not insert metal wires or other foreign matter into the pressure measurement port.
It can damage the Pressure Sensor causing failure or malfunction.
Wiring
Do not pull the lead wires.
In particular, never lift a Pressure Sensor equipped with fitting and piping by holding the lead wires.
Avoid repeatedly bending or stretching the lead wire, or placing heavy load on them.
Repetitive bending stress or tensile stress can cause the sheath of the wire to peel off, or breakage of the wire.
If the lead wire can move, fix it near the body of the product.
The recommended bend radius of the lead wire is 6 times the outside diameter of the sheath, or 33 times the
outside diameter of the insulation material, whichever is larger.
Replace the damaged lead wire with a new one.
Wire correctly.
Incorrect wiring can break the Pressure Sensor.
Do not perform wiring while the power is on.
Otherwise damage to the internal parts can result, causing malfunction.
Do not route wires and cables together with power or high voltage cables.
Otherwise the product can malfunction due to interference of noise and surge voltage from power and high
voltage cables to the signal line. Route the wires (piping) of the product separately from power or high voltage
cables.
Confirm proper insulation of wiring.
Poor insulation (interference from another circuit, poor insulation between terminals, etc.) can lead to excess
voltage or current being applied to the product, causing damage.
Keep wiring as short as possible to prevent interference from electromagnetic noise and surge voltage.
Do not use a cable longer than 30 m.
Wire the DC(-) line(blue) as close as possible to the power supply.
Ensure that the FG terminal is connected to ground when using a commercially available switch-mode
power supply. When a switch-mode power supply is connected to the product, switching noise will be
superimposed and the product specification can no longer be met. This can be prevented by inserting
a noise filter, such as a line noise filter and ferrite core, between the switch-mode power supply and
the product, or by using a series power supply instead of a switch-mode power supply.

Environment
Do not use the product in area that is exposed to corrosive gases, chemicals, sea water, water or
steam.
Otherwise failure or malfunction can result.
Do not use in a place where the product could be splashed by oil or chemicals.
If the product is to be used in an environment containing oils or chemicals such as coolant or cleaning solvent,
even for a short time, it may be adversely affected (damage, malfunction, or hardening of the lead wires).
Do not use in an area where electrical surges are generated. (EMI or Electro Magnetic Interference)
If there is equipment which generates a large amount of EMI (solenoid type lifter, high frequency induction furnace,
motor, etc.) close to the Pressure Sensor, this may cause deterioration or breakage of the internal circuit of the
Pressure Sensor. Avoid sources of surge generation and crossed lines.
The product is CE marked, but not immune to lightning strikes. Take measures against lightning strikes
in the system.
Mount the product in a place that is not exposed to vibration or impact.
Otherwise failure or malfunction can result.
Prevent foreign matter such as remnant of wires from entering the Pressure Sensor.
Take proper measures for the remnant not to enter the Pressure Sensor in order to prevent failure or malfunction.
Do not use the product in an environment that is exposed to temperature cycle.
Heat cycles other than ordinary changes in temperature can adversely affect the inside of the product.
Do not expose the product to direct sunlight.
If using in a location directly exposed to sunlight, shade the product from the sunlight.
Otherwise failure or malfunction can result.
Keep within the specified fluid and ambient temperatures range.
The fluid and ambient temperatures should be -10 to 60 °C. Operation under low temperature leads to cause
damage or operation failure due to frozen moist in the fluid or air.
Protection against freezing is necessary. Air dryer is recommended for elimination of drain and water.
Avoid sudden temperature change even within specified temperature.
Do not operate close to a heat source, or in a location exposed to radiant heat.
Otherwise malfunction can result.
Adjustment and Operation
Do not short-circuit the load.
If using the product to detect very small pressure rates, warm up the product for 20 to 30 minutes first.
There will be a drift on the analogue output of approximate 1% immediately after the power supply is turned on,
within 10 minutes.
Maintenance
Turn off the power supply, stop the supplied air, exhaust the residual pressure and verify the release of
air before performing maintenance.
There is a risk of unexpected malfunction.
Perform regular maintenance and inspections.
There is a risk of unexpected malfunction.
Perform drainage regularly.
If condensate enters the secondary side, it can cause operating failure of pneumatic equipment.
Do not use solvents such as benzene, thinner etc. to clean the Pressure Sensor.
They could damage the surface of the body and erase the markings on the body.
