Differential pressure sensor measures with ±0.5 % accuracy

The EE600 from E+E Elektronik measures the differential pressure in the range of 0...1000 Pa or 0....10 000 Pa with an accuracy of ±0.5 % of the final value. The sensor is intended for HVAC applications and is suitable for air and all non-flammable and non-aggressive gases.

The differential pressure sensor from E+E Elektronik is ideal for reliable differential pressure measurement in ventilation and air conditioning ducts and for filter monitoring. The sensor is available in two versions for pressures up to 1,000 Pa and 10,000 Pa. Four pressure measuring ranges can be set via DIP switches (0...250 / 500 / 750 / 1,000 Pa or 0...2,500 / 5,000 / 7,500 / 10,000 Pa). The piezoresistive pressure sensor element works without gas flow and has a high long-term stability.

Analog output and display

The EE600 provides the measured values as current and voltage signals at the spring terminals. The large, illuminated graphic display clearly shows the measured differential pressure in [Pa], [mbar], [inch WC] or [kPa]. The robust IP65/NEMA 4 housing with external mounting holes allows the sensor to be mounted quickly with the cover closed. This saves time during installation and protects the electronics from dirt and damage. A knockout opening for a ½" conduit connection is provided on the housing for the American market.

Full configurability

The EE600 offers extensive adjustment and configuration options. DIP switches on the circuit board can be used to set the various pressure measuring ranges, the output signal, the response time, the unit for the measured values and the display illumination. A zero point and end value adjustment can also be carried out using buttons.
