The digital differential pressure indicator A1 is a microprocessor-based transmitter for differential pressure measurement, low or very low pressure, it can be replaced directly by mechanical instruments.
The digital differential manometer series A1 uses an extremely stable piezoresistive sensor to give a standard scale accuracy of 1%. For applications that require greater precision, the A1 is also available with 0.5% or 0.25% accuracy. The equipment also has an optional 4-20 mA output for applications that require an output signal.
The A1 has a bright LED display, which gives the instrument a better view from any angle.
Digital differential pressure meters from A1 also have 5 engineering units selectable by the user, in particular in. Wc, mm water column, cm wc, kPa and Pa
