The EE600 from E+E Elektronik measures the differential pressure in the range zero to 1,000 Pa or zero to 10,000 Pa with an accuracy of ±0.5 % of the full scale. The sensor is dedicated for HVAC applications and can be employed for air and all non-flammable and non-aggressive gases.

The EE600 is ideal for reliable differential pressure measurement in ventilation and air conditioning systems or for filter monitoring. The sensor is available in two versions for up to 1,000 Pa or 10,000 Pa. Four different measuring ranges (Zero to 250, 500, 750, 1,000 Pa or zero to 2,500, 5,000, 7,500, 10,000 Pa) are selectable via DIP switches. The piezo-resistive, no flow-through pressure sensing element stands for outstanding long-term stability.

The measured data is available as voltage and current signals at the spring loaded terminals. The large, backlit graphic display shows the reading in [Pa], [mbar], [inch WC] or [kPa].

The robust IP65 / NEMA 4 enclosure with external mounting holes facilitates mounting the sensor with closed cover. This saves time and also protects the electronics from pollution and mechanical damage during installation. For US requirements, the enclosure features a knockout for a ½”conduit fitting.

The EE600 offers various adjustment and configuration options. Via DIP switches on the electronics board, the user can set the pressure measuring ranges, the output signal, the response time as well as the units and the backlight for the display. Also a zero and span point adjustment can be easily performed with push buttons.
