Spec Change

Change of material
We are pleased to announce that the material SUS630 (vacuum melting material) used in our long seller "strain gauge series" is changed to a material that has been widely used in aerospace industry and can be procured stably in future as described below.

Models concerned
Pressure Transmitter VPRT(F), VPRQ(F), VPVT(F), VPVQ(F), VPRF
Pressure Sensor VPRT(F), VPVT(F), VPRQ(F), VPVQ(F), VPRF, VPRH

All ranges of models listed above


(1) Before change:SUS630(Vacuum melting material used)
(2) After change:15-5PH(Vacuum melting material used)

15-5PH is a variant of SUS630 with improved mechanical characteristics. Although 15-5PH is a precipitation-hardened stainless steel outside the scope of JIS standard, it is controlled under the Aerospace Material Specifications: AMS5659. Therefore its control level is the same or better than that of JIS.


15-5PH is classified into precipitation-hardened stainless steel in terms of tensile strength, substances of concern, and corrosion resistance. Therefore, it has characteristics equivalent to those of conventional SUS630 (Vacuum melting material).

3.Accuracy and performance

Accuracy and performance such as non-linearity, hysteresis, repeatability, temperature characteristics and durability are the same as those of conventional material.

4.When to change

Please note that, since October 2011, the new material has been introduced to each model as a running change, as soon as the current stock runs out.

Even after the material is changed, the new products can be used as safely and reliably as the conventional models.
We ask for your kind understanding.

Spec change for VALCOLOR(Digital panel meter)

I guide as below so that we can change specifications VALCOLOR.
* Will add / change the input range.

Model the current input signal  N : Select 4~20mA / 0~5V / 1~5V / 0~10V
Model input signal after the change  N : Select 4~20mA / 0~5V / 1~5V
A5: Select 0~10V / 4~20mA
Time change June 2012 start
