Ⅲ． INSTALLATION
Before using this instrument, make sure if it is the type that you requested and meets the demand of the
environment, pressure and piping conditions where it is used, by specifi cation.
1. Caution of service condition
a) Do not use the instrument in a place subjected to direct sunlight, vibration or shock, or excessive
moisture. In particular, vibration and shock to the instrument should shorten its life.
b) Use under the medium and ambient temperature from - 10 to + 50 ℃ .
c) The instrument is not waterproof. Do not use it in a place subjected to rain, or other splashing water.
d) The instrument cannot be installed outdoors without an appropriate protection. If outdoor installing is
required, the instrument should be housed in a box of drip-proof type for outdoor use.
e) In installing the instrument, select the place where the ground is smooth and fl at.
2. Installation of MS65, MS65F
Panel cut size
3. Pressure of measurement and connection of piping
a) Measurement of positive pressure
Connect the tube to the high pressure side piping connector (indicated by red color or letter H). The
lower pressure port (blue or L) should opened to atmosphere, but do not remove the piping connector.
b) Measurement of negative pressure
Connect the tube to the low pressure side piping connector (blue or L). The high pressure port (red or H)
should be opened to atmosphere, but do not remove the piping connector.
c) Measurement of differential pressure
Connect the tube from the high pressure piping connector to the high pressure port (red or H) and from
the low pressure piping connector to the low pressure port (blue or L).
4. Connectors and piping material
a) Connectors for vinyl or plastic tube (VT, VL, VK connectors)
These are connectors for vinyl, plastic or rubber tubes. Be sure to use I.D. 6 and thickness of 1 mm or
more. However, the vinyl or plastic tube (2 or more wall thickness) with enough withstanding pressure
(including vacuum pressure) is required when the instrument range or the line pressure is higher more
than 50 kPa.
b) Connectors for metal tube (MT, ML, MK connectors)
These piping connectors can be connected to metal
tube made from copper and aluminum and so on.
(O.D. 6, tolerannce ± 0.1, ring joint type)
When this connector is connected to hard plastic
tube (O.D. 6, I.D. 4), remove the sleeve made of
bress and use the resinous inner sleeve set (XIN6 ×
4) that is the optional accessory.

Caution
Tighten the piping
connectors with the torque
of 1 N･m.
Do not apply excessive
torque more than
necessary, otherwise it
will damage the instrument
body.
