Pressure transmitter with volumetric flow measurement DPT-MB-D

differentialanalog4-20 mA

Modbus communication. Modbus enables own text to be displayed. 14-bit resolution on pressure element. Illuminated display. Flow calculation via K factor. K factor adjustable at two decimal place Adjustable stop bits, regardless of selected parity. The display shows the current output signal. High accuracy. Installation-friendly enclosure Removable cable port and terminal block Supplied with 2 m hose and 2 nipples. 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.
