CD21 Flameproof Type Pressure Gauge
CD21 Flameproof Type Pressure Gauge
This flameproof pressure gauge with contacts is used for hazardous area where there is the consideration of
pressure media or atmosphere igniting or exploding. It is especially applicable when pressure indication is necessary at the job site for pressure measurement, alarm, and control applications.

Feature
・Pressure indication featured with switch actuation is suitable for on-site pressure contorl.
・Since the case is made of die cast aluminum alloy, it is lightweight and rugged.
・Contacts setting adjustable by external adjustment knob.
・There is no effect on each indication and switch functions because the indication and switching sensing
element are separated.
＊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.
