Pressure Gauge
Gas measurement
interface with
silicon diaphragm
Outline
Battery-operated digital differential pressure gauge
suited for HVAC and semiconductor manufacturing
field monitoring. Easy to install without wiring or
detect the filter crogging with comparator output
using optional external power source.
Features
•17mm large LCD (3 1/2 digit)
•Analog bar graph display to know a
measurement situation
•Comparator output with external power cable
(Option)
•Filter, Peak & bottom holding and Zero
adjustment function
Function
Features of sensor
Silicon capacitance (SC) Sensor
Because of its simple construction
designed with moving parts fewer
than ever, combined with a fine,
micro silicone diaphragm, the sensor
is very resistant to vibrations and
shocks.
Actual size
•Easy to know the measurement situation by analog
bar graph display.
•When using the external power source,
comparator one-output is available. (Option)
