Specification
Feature
・Pressure indication at facility
・Direct control of device possible with large switching current
・Pressure indication after switch operates is accurate as pressure sensing element for indication and switch
action are both independent
・Micro switch assures stable snap action switching
・Pressure indication and switch operating setting dial are independent for arbitrary switch settingRecommended pressure setting range
Upper limit: (10%F.S. + deadband) to 90％F.S.
Lower limit: 10%F.S. to (90%F.S. – deadband)
%F.S. refers max.P. for receiver range.＊To maximize performance, select full scale pressure range to indicate normal operating pressure which comes to conditions below.
For constant pressure : The maximum operating pressure should not exceed three-quarters of the full-
scale range.
For fluctuating pressure: The maximum operating pressure should not exceed two-thirds of the full-scale
range.
Select appropriate wetted parts compatible with process fluid (gas and liquid) which the gauge will be
subjected.
Please refer to JIS B 7505-1 for details.
