Capteur de niveau - NH3

Fiche technique: HBLT-A2

L’ émetteur de niveau capacitif de liquide HBLT-A2 est utilisé pour mesurer les niveaux de liquide dans les réservoirs de fluide frigorigène. Le HBLT transmet un signal actif de 4 ou 20 mA qui est proportionnel au niveau du liquide : à 4 mA lorsque l’émetteur n’enregistre pas le liquide et 20 mA lorsque l’émetteur est intégralement entouré de liquide. Au contraire du HBLT-A1 on peut configurer l’électronique: Au moyen du logiciel on peut régler 3 paramètres. Il y a un visuel au lieu d’ un bar graph. Un microprocesseur intégré fait un signal 4 – 20 mA et travaille proportionellement de la gamme de mesure du capteur. En plus il y a un controleur intégré pour régler un clapet. Le circuit de cable peut demander de nous aussi.

Le nouveau HBLT-A2 est sans surcharge, mais il y a plus des possibilitées en regard de 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.
