HFC Kølemiddel wire-sensor

Teknisk data: HBLT-Wire

HBLT-wire er en kapacitice sensor til niveau måling af HFC kølemiddel i industrielle køleanlæg. Sensoren har et udgangssignal på 4-20 mA, som er proportional med 0 og 100 %. Ved tom beholder afgiver den 4 mA og ved fyldt beholder afgiver den 20 mA. HBLT-wire kan tilpasses i længden til den aktuelle applikation. Sensor elementet består af en 2 mm stålwire samt en teflon slange. Begge dele leveres i en længde af 4 m og kan afkortes med skævbider eller anden tang. HBLT-wire kan anvendes i forbindelse med HBLT-C1 controller til styring af pumpe m.m.

HBLT-WIRE - Counterweight with adjustable center position spring

Under turbulent conditions, the counterweight for the HBLT-WIRE can be supplied as a spare part with an adjustable center position spring. The center position spring is delivered with cutting marks so it can be adapted and cut to the dimension of the stand pipe.                                                        HBLT WIRE Counterweight 2217 fritlagt hvid baggrund Web

Product features

Flexible sensor stav (wire) som  kan tilpasses en længde på 600…4000 mm.
Robust og pålideligt design med standard 4-20 mA udgangssignal.
Designet til køleindustrien - max tryk 100 bar.
Split design hvilket gør sensoren nemt at montere og servicere. Elektronikken kan adskilles fra den mekaniske del. 
Enkel kalibrering til den givne længde.
Kompakt design der minimere omkostninger til forsendelse.
Kan anvendes til Marine applikationer da målingen ikke bliver forstyrret ved kontakt med standrørs metaloverflade.
Måler HFC kølemiddel.

Applications

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 rod-style sensor.

For Stand-pipes with turbulent conditions (a lot of turbulence, cooking, foaming, liquid from the top):

• Use a HBLT-A2 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 the 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 rod-style sensor.

Sensoren kan sættes op til analog måling af tank niveauet eller som ventil regulering ud fra et ønsket set-punkt (som en svømmerstyring i eksempelvis chillere)
