DPT-MB-D is designed for measuring differential pressure in HVAC/R, ventilation systems and building automation.
Differential pressure or volume flow calculation is selected on the display, along with the K factor for volume flow calculation, zero calibration of the pressure element and the Modbus settings.
As DPT-MB-D has no analogue output signal, there is no setting for measurement ranges.
Via the K factor settings, DPT-MB-D can measure the volume / flow over, e.g., fans or orifice plates… The conversion formula from differential pressure to volume is: q = k x √∆p.
K factor can be rounded up to two decimal places. The following units can also be set: m³/h, m³/s and l/s. The unit setting is only a “display label” and not a mathematical calculation of the value.
Basic display mode shows the current measured value. Modbus also enables own text to be displayed:
– At the bottom of the display is a row with room for 10 characters.
– Measured value (4 large characters) and any selected unit (2 characters).
– Predefined units (Pa, m³h, m³s and l/s) can also be used.
