●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
R1/4
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. (Tensile force 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.
