Precautions for use
(1) Installation
1) Where the product is connected to the pressure line, DO NOT tight the main body of the case with pipe
wrench, etc.
For installation, make sure to use hexagonal part of connecting screw
2) When installing to pressure line, DO NOT install the product while liquid is filled up in the pipe.
Since liquid is incompressible, tightening a connecting screw may generate high pressure and
instrument failure.
When installing to the existing pressure line or in the case of replacement, drain the liquid inside the
piping connection side and install the product with leaving air of about 15 to 20 mm.
3) Although this product has high vibration resistance, since this product is a measuring instrument, be
careful not to apply severe vibration.
･ Use this transmitter at an ambient temperature of - 20 to 70℃. (For 0 to 0.1MPa or
･ Secure a space wide enough to allow maintenance and adjustment.
･ Where temperature of the liquid contact area may reach 70℃ (in case of steam, hot
Caution
(2) Cable specifications
Where cable sheath is removed, in case of current output (2-wire type), there are green and blue
wires besides red and white wires since cable main body consists of 4 wires. However, those green
and blue wires are not used (No inside connection).
In case of voltage output (3-wire type), there is blue wire besides red, white, and green wires.
However, blue wire is not used. (No inside connection)
Specifications of cables are as follows:
Shield cable (Standard)
Heat-resistant cable
Cold-resistant cable
(3) Cautions for transportation and control
1) Cautions for transportation
Since this product is a precision measuring instrument, pay enough attention when transporting
the product. Drop or shock may cause a fatal damage.
2) Cautions for unpacking
Before unpacking, check the appearance of the package.
When unpacking, handle the package with care.
When bringing out the product from the packaging box, be careful not to drop the product.
After unpacking, check if there is any damage on the external surface and the product type is
correct as it is ordered.
If any abnormality is found, contact the distributor or NKS sales office.
less, use it at 0 to 70℃)
water and etc.), make sure the temperature does not exceed 70℃ by using pipe
syphon, etc. Also, if this transmitter is installed directly within the piping of low
temperature fluid, it may cause condensation on the detection sensor part and result in
failure. Make sure to take countermeasures against condensation.
