The DPS 200 ventilation air dp sensor has been designed particularly for measuring draft air pressures in ranges that are typically used in air condition systems for office blocks and factories to monitor airflow.
The DPS200 hvac differential pressure sensor is housed inside a ABS plastic box which can be mounted on the wall or inside an instrument cabinet. An LCD display can be integrated into the front cover of the sensor housing for local indication of the air pressure.
The LCD display can be configured in the factory for reading the pressure in any units such as inches of water, millibar or pascals. The lower portion of the display shows the units the sensor is calibrated to measure and a 52 segment bargraph shows the reading a percentage of the full scale range.
Push-on flexible tube fittings and a M12 x 1.5 cable gland are fitted as standard for installing pressure hoses and electrical wiring connections.
2 or 3 wire 4 to 20 milliamp can be specified for industrial process plant control systems or 0 to 10 volt for commercial building utility management systems.
Output signal response
On the DPS200 data sheet, it says that the response time can be adjusted from 500 msecs to 2.5 secs, and it also says that the measuring rate is 1 kHz, please could you explain which spec should be used to determine the response of the output signal?
The Response time is after the averaging and filtering has been applied. The measuring rate is the speed at which the sensing element is measured by the signal conditioning inside the DPS200 before the averaging and filtering processes. A faster measuring rate allows the collection of more data, which leads to a more accurate output reading after conditioning.
Are bi-directional ranges possible with the DPS200 HVAC differential pressure transducer?
Yes it is possible to scale the electrical signal output over a combined negative and positive pressure range, e.g. -1000 Pa = 0 volts dc and +1000 Pa = 10 Volts dc.
