MKA

描述:
Suitable for measurement of positive pressure, vacuum or
differential pressure.

Media: compressed air or non-corrosive gases
Overpressure: see chart
Supply_voltage: 15...30 V DC standard, optionally 230 V AC ± 10%
Electrical_connector: plug with 7-pin screw terminal for cable
cross-sectional area 0.14...1.5 mm²

Pneumatic_connection:
P+: pos. pressure
P-: vacuum
P+/P-: differential pressure, the higher pressure is to
be connected at P+;
