FEATURES
●
Separate amplifier-type pressure sensor
Faster response is achieved by reducing the total capacity of piping.
●
Two-color, LED digital display
High-intensity, two-color LED ensures high visibility. Four types of
display patterns are selectable.
●
Chattering prevention function
The instantaneous drops in base pressure due to the activation of a
large-bore ejector or other devices can be canceled. This eliminates
the need for preparing a sequence program.
●
Automatic sensor head recognition function
When the power is turned on, the amplifier checks the sensor head
connection automatically. A recognized sensor head type appears
green on the display for 0.5 seconds.
●
Industry's smallest and lightest sensor head (AP-41M)
This sensor head with half the volume of conventional models
weighs only 4.8 g, enabling flexible mounting.
●
High-resolution mode (AP-40RA)
The resolution can be multiplied temporarily by 10 to stabilize
detection of minute differential pressure.
●
Zero-shift function (AP-40RA, 40ZA)
The current pressure value can be reset to 0 at any time in order to
prevent measurements from being affected by fluctuations in base
pressure.
