•Applicable fluid is a fluid that does not corrode Al
.
plating) 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.
•Use the specified measurement flow rate and operating pressure.
Otherwise it can cause damage to the pressure switch or inability to measure correctly.
•Since this product uses an O-ring seal in the pressure-receiving area, the product life may be affected if
pressure is applied with high frequency. Please contact our nearest sales office, especially when using
the product for applications where pressure around 16 MPa is applied at a high frequency of 1 time/min
or more.
•If a gas (such as high-pressure gas) is used as a fluid, this product may leak. For applications where
high-pressure gases are to be detected as a fluid, leakage from the seal must be taken into account.
Alternatively, contact our nearest sales office.
•Reserve a space for maintenance.
Allow sufficient space for maintenance when designing the system.
●Product handling
Installation
•Tighten to the specified tightening torque.
If the tightening torque is exceeded the mounting screws and brackets may be broken.
If the tightening torque is insufficient, the product can be displaced and loosen the mounting screws.
•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 switch.
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. (Tensile force 35 N or less)
Hold the body when handling to avoid the damage of the Pressure switch which lead to cause the failure and
malfunction.
•For piping of the Pressure switch, 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 switch.
•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.
•Never mount a Pressure switch in a location that will be used as a foothold.
The product may be damaged if excessive force is applied by stepping or climbing onto it.
•If the entering of foreign material to the fluid is possible, install and pipe the filter or the mist separator to
the inlet to avoid failure and malfunction.
Wiring
•Do not pull the lead wires.
In particular, never lift a Pressure switch equipped with fitting and piping by holding the lead wires.
Otherwise damage to the internal parts can result, causing malfunction or to be off the connector.
•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.
