Now available from Technical and Scientific Equipment , the Halstrup Walcher EMA 200 digital manometer is a battery operated, digital pressure sensor for measuring the overpressure, vacuum and differential pressure of non-aggressive gases.
With measuring ranges varying from ±200 Pa to ±200 kPa, this portable digital pressure gauge is robust, simple to operate, and includes an analogue output.
This pressure sensor 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 output. A scalable 0-2V analogue output is available in addition to the digital display, and measurements can be converted between different units, including Pa, kPa, mmHg, mmH2O and inH2O.
These differential digital pressure gauges also have a minimum/maximum value memory and can be used for measuring positive and negative, low to mid range differential pressures. Flow-rate measurements are also possible through the addition of a pitot tube.
These portable digital pressure gauges are ideally suitable for maintenance, customer service and record-keeping for heating, ventilation and air-conditioning units.
