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
The direct current power supply to combine should be UL approved as follows.
Circuit (of Class2) which is of maximum 30 Vrms (42.4 V peak) or less, with UL1310 Class2 power supply unit or
UL1585 Class2 transformer.
The Pressure Sensor is a UL approved product only if it has a
mark on the body.
Use the specified voltage.
Otherwise failure or malfunction can result.
For the details of compressed air quality, refer to ISO 8573-1, 1.1.2 to 1.6.2: 2001.
This can cause operating failure.
If compressed air containing condensate is used, install an air dryer or drain catch before the filter and perform
drainage regularly.
If drainage is not performed regularly and condensate enters the secondary side, it can cause operating failure of
pneumatic equipment.
If regular drainage is difficult, the use of a filter with an auto drain is recommended.
Applicable fluid is air, inert gases and incombustible gases.
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 Sensor or inability to measure correctly.
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 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 50N 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.
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.
Do not apply unnecessary forces such as twisting, pulling, moment loads, etc. on fittings or tubing.
When the tube of other company is used, ensure the tube has the accuracy of inside diameter within
±0.3 mm.
Insert into pipe precisely so that air tube will not come off. (Tensile strength is approximate 25N at
8 mm inserted.)
