Features
The EMA 84 is a battery-operated, digital precision pressure gauge for measuring
overpressure, vacuum and differential pressure of non-aggressive gases. Operating
range is 100 Pa to 100 kPa.
Because it is robust, easy-to-use and includes an analog output, this instrument is
especially suitable for maintenance, customer service and record-keeping for heating,
ventilation and air-conditioning units.
At its heart is a pressure measurement capsule with a beryllium bronze membrane
spring, which is displaced by the pressure difference between the two chambers of
the measurement capsule. A distance measurement system converts this
displacement into an electrical signal.
