The EMA 200 digital manometer from Halstrup Walcher is capable of measuring ranges from ±200 Pa to ±200 kPa. This digital pressure gauge runs on a battery and can be used to measure overpressure, vacuum and differential pressure of non-aggressive gases.
Since this portable digital pressure gauge is robust, easy-to-use and includes an analogue output, it is especially suitable for maintenance, customer service and record-keeping for heating, ventilation and air-conditioning units.
The pressure gauge produces readings by measuring the displacement of a membrane due to the pressure difference between the two chambers of the measurement capsule. A semiconductor sensor is used for measuring pressures in the area of 200 kPa.
The linearity of this pressure sensor is approximately 0.5% of the output. A scalable 0-2V analogue output is available in addition to the digital display. Measurements can be converted between different units, including Pa, kPa, mmHg, mmH2O and inH2O.
The differential pressure gauge also has a min/max value memory and can be used for measuring positive and negative, low to mid range differential pressures. Flow-rate measurements are possible through the addition of a pitot tube.
