NH3 Füllstandsensor

Technische Daten: HBLT-A2

Der kapazitive Sensor HBLT-A2 ist ein Füllstandsensor und dient zur Messung von Kältemittelfüllständen in industriellen Kälteanlagen. Der Sensor sendet ein 4-20 mA Signal: 4 mA im “trockenen Zustand” und 20 mA, wenn der Sensor von flüssigem Kältemittel umgeben ist.Im Unterschied zum HBLT-A1 ist die Elektronik konfigurierbar: Mit Hilfe der HB Software können 3 Parameter eingestellt werden. Ein Display ist vorhanden anstelle eines Bar Graphs; ein integrierter Mikroprozessor liefert ein 4-20 mA Signal, das proportional zum Sensormessbereich arbeitet. Ausserdem hat der Sensor einen integrierten Controller, um autonomy ein Ventil ansteuern zu können. Die erforderliche direkte Kabelverbindung zum Ventil kann auf Wunsch ebenfalls geliefert werden.

Der HBLT-A2 ist ohne Aufpreis, bietet aber mehr Möglicheiten als sein Vorgänger (HBLT-A1).

Applications

Use of HBLT-A2

When using a level sensor for measuring Ammonia in a compact plate and shell heat exchanger or other systems with turbulent conditions, we have new recommendation based on recent experience:

For Stand-pipes with stable conditions (smooth changes in the level):
• Use a HBLT-Wire or a HBLT-A2 or HBLT-A1 rod-style sensor.
  For Stand-pipes with turbulent conditions (a lot of turbulence, cooking, foaming, liquid from the top):
• Use a HBLT-A2 or HBLT-A1 rod-style sensor, or
• Use only a HBLT-Wire sensor when you have it mounted in an inner guide-tube of e.g. DN25 as
  illustrated. The guide-tube will dampen the turbulence and the foaming and you will have a good
  measurement.
• If HBLT-Wire sensor is already mounted under these conditions WITHOUT a guide-tube, do
  eventually set the filter time function between 60-120 seconds to dampen the signal from the
  turbulent conditions.

For tank/drum installation:
• Use a HBLT-A2 or HBLT-A1 rod-style sensor, or
• Use only a HBLT-Wire sensor when you have it mounted in an inner guide-tube of e.g. DN25 as
  illustrated. The guide-tube will dampen the level and the foaming and you will have a good
  measurement.
• If HBLT-Wire sensor is already mounted under these conditions WITHOUT a guide-tube,
  do eventually set the filter time function between 60-120 seconds to dampen the signal from the
  turbulent conditions.

For Alfa Laval U-turn evaporator:
• Use a HBLT-A2 or HBLT-A1 rod-style sensor.

 

 

 HBLT A2 U TURN

HBLT/C-A2, here’s a cable connection directly to a modulating fluid valve

such as Siemens MVS661, this will save installations cost because there is built

in a level controller in the sensor head.
