MHA-C1 AirCom Pneumatic

A piezo-resistive pressure sensor converts the input pressure
into a digital electrical signal which is displayed on the LCD.
On-off switch is located at the side of the plastic housing.

Media: compressed air or non-corrosive gases
Overpressure: see chart
Pneumatic_connection:
P+: pos. pressure
P-: vacuum
P+/P-: differential pressure, the higher pressure to be connected
at P+ plug nipple up to 1 bar, sleeve with union nut from 2 bar on,
each for hose internal diameter of Ø 4 mm

Voltage_supply: 9 V battery, 2.5 mA, type 6F22 or PP3 or similar

Display:
31/2-digit LCD display, max. ± 1999, 12 mm tall, black numbers,
low battery display at low voltage, red LED lights up at overpressure,
then measurement is faulty

Output_signal: optionally 0...1 V
Impedance: > 2 kΩ terminal for 2.5 mm 2-pin jack plug
Zero_point: All devices have a potentiometer for rough adjustment of
zero point at the side of the housing.
