NH3 Niveau sensor

Technical data: HBLT-A2

HBLT-A2 capacitive liquid level transmitters are used to measure liquid levels in refrigerant vessels. The sensor transmits a current signal from 4 to 20 mA (4 mA when the transmitter
does not register liquid - and 20 mA when the entire transmitter is surrounded by liquid).
The difference between the new HBLT-A2 and the HBLT-A1 is the electronic head. We have used the electronic head from our HBLC sensor, which gives more opportunities in the PC tool for configuration with 3 parameters to set up the sensor. 

HBLT-A2 has a digital display instead of the bar graph known from HBLT-A1 and HBLT-A2 is an intelligent sensor with a built-in microprocessor. It emits a 4-20 mA signal, which is proportional to the sensor’s set range of measurement. Apart from the 4-20 mA signal the sensor also has a built-in controller. The controller can be set-up with all the parameters necessary for controlling a modulating motor valve. The sensor can be delivered with a cable for direct supply to and control of motor valves.

HBLT-A2 provides new possibilities but has the same price as 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 Alpha 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.
