Pneumatic components: Warning and Cautions
Design/selection
DANGER
Do not use this product for flammable fluids.
Working fluids
WARNING
This product cannot be used as a business
meter.
Do not use this product for commercial
transactions as it is not compliant with the
Measurement Act. Intended applications include
industrial sensors.
For fluids other than the applicable fluid, the
accuracy is a reference value.
Use dry gas which does not contain corrosive
elements such as chlorine, sulfur or acids, and
which is clean and does not contain dust or oil
mist.
Depending on the fluid, retaining the fluid
for long periods could adversely affect the
performance. Do not seal the fluid in the pipe for
long periods of time.
When using compressed air, use clean air that
complies with JIS B 8392-1: 2012 Class 1.1.1
to 1.6.2. Compressed air from the compressor
contains drainage (water, oil oxide, foreign
matter, etc.). So install a filter, air dryer, and oil
mist filter (micro alescer) on the primary side
(upstream side) of the sensor. The sensor's
mesh rectifies flow in the pipe. It does not filter
out foreign matter, so provide a filter.
Working pressure/flow rate range
Applications exceeding the max. working
pressure and specified flow rate range may
result in faults. Use this product only within
the specified range. If energized in a vacuum
state of −0.07 MPa or less, the sensor's heat
dissipation will suffer, leading to degradation of
the sensor.
DANGER
Working environment
Explosion-proof environments
WARNING
Corrosive environments
Do not use this product in an atmosphere
containing corrosive gases such as sulfur dioxide.
Ambient/fluid temperatures
Use ambient temperature/fluid temperature from
0 to 50°C within specified range.
Even if the temperature is within the specified
range, do not use this product if the ambient
temperature and fluid temperature could
suddenly change and cause dew to condense.
Drip-proof environments
The degree of protection of this product is
equivalent to IP40. Do not install this product
where water, salt, dust, or swarf is present or in
a pressurized or depressurized environment. The
product cannot be used with large temperature
variations or high temperature/humidity since
condensation may occur inside the body.
Never use this product in an explosive gas
atmosphere. The structure is not explosion-
proof, and explosions or fires could occur.
[Recommended values]
When using a valve on the primary side of
the sensor, use only valves with oil-prohibited
specifications. This sensor could malfunction or
fail if exposed to splattering grease, oil, etc. As
friction powder may be generated depending on
the valve, mount a filter to prevent the powder
from entering the sensor.
When using liquefied gas such as carbon
dioxide, always vaporize it first. If liquefied gas
enters the product, it may result in failure.
