SCHMIDT® LED measured value display MD 10.010/10.015

The ideal solution for displaying and calculating measured values at the place of use

 

  • Compressed air technology
  • Industrial processes
  • Cleanroom and pharmaceuticals
  • Ventilation and air-conditioning

 

Sensors must be mounted into positions specified by metrology. In practice, a sensor display is often not very helpful, since it cannot be recognized or isn't even visible from far away. However, an on-site display near the sensor is often useful. It is important that calculated measured values such as m³/h or totalized volumes are also displayed and retransmitted as analog output signal.

 

The SCHMIDT® LED displays MD 10.010 and 10.015 meet these requirements perfectly. They have been designed as large-sized wall display and can be mounted in any readily accessible position. The analog output signals are scaled by one (MD 10.010) or two sensors (MD 10.015) and displayed. In addition, an analog value (4 … 20 mA or 0 … 10 V) is provided via a galvanically separated analog output. Furthermore, the values can be used to define switching points and output directly via two relays.

 

The power supply can be provided by the mains voltage or via 24 Volt (DC) – the connected sensors are supplied with power directly by the LED display.

 

Typical application examples in connection with SCHMIDT® flow sensors

 

  • Detection of the consumed compressed air volume
  • Detection of backflow in circular pipelines
  • Display of the leakage volume on site
  • Verification of the minimum compressed air volume in the system (site of consumption)
  • Display of the air flow of extraction systems
  • In-process detection of gas volumes
  • Display of the measured laminar flow
  • Display and alarm function for room overflow applications
  • Direct display of the actual volumetric flows on the duct
  • Switching of fans or dampers when values exceed or fall below limit values on site
  • Detection of backflows (e. g. in soiled filters)

 

Their advantages at a glance:

  • Sturdy plastic housing IP65 for wall assembly
  • Settings are retained even after a power failure
  • Simple and quick assembly directly on wall or duct
  • Freely programmable for all sensors and measuring transducers (e. g. temperature, pressure or humidity sensors with 4 – 20 mA or 0 – 10 Volt on output signal)
  • Adjustable averaging
  • Output of calculated measured value (e. g. volumetric flow) as display and analog signal
  • Configurable relay alarm outputs (e. g. falling/rising flank)
  • Power supply of the connected sensor

 

Know where the wind is blowing from: Measuring the value and direction of flow with SCHMIDT® flow sensors and LED displays

 

In practice, for example in ring main compressed air pipes or circulation ducts, it very often happens that the flow does not always come from the same direction. This greatly affects the determination of the consumption rates: It leads to incorrect results, because the backflow through the flow meter is also added to the forward flow rather than subtracted. The mechanical (paddle) switches for flow detection used nowadays for solving the problem are not capable of detecting the direction of flow with small flow volumes, resulting in relatively inaccurate volume measurements.
