Vapor Quality Sensor, Inline

Teknisk data: HBX-OVC

HBX-OVC er en ny revolutionerende patent anmeldt sensorteknologi, og dermed den første sensor i verden, der er i stand til at måle forholdet mellem gas og væske i et køleanlæg. Sensoren måler tørhedsgraden "X" af gassen i rørledingen, værdien omsættes til et analogt signal 4-20 mA svarede til "X". HBX-OVC måler i området X = 0.6...0.9.

Sensoren leveres i to varianter ”Rod style” til montage i en rørbøjning hhv “In-line” til i svejsning i sugeledningen, og ligeledes til oversømmet system design samt DX system design.

Sensoren måler med meget stor præcision og udlæser momentant gas-kvaliteten, hvilket gør den anvendelig til de fleste fordampertyper (plade, rør, luft-fordampere).
Sensorens mikroprocessor fungerer også som controller således at styring af en modulerende motorventil kan udføres direkte, altså uden om ekstern controller eller PLC styringen. Controlleren kan opsættes med alle de parametre der er nødvendige for at regulere en modulerende motorventil eller en stepper motor ventil. Sensoren kan leveres med kabel for direkte forsyning til og regulering af motorventil eller som en sensor, hvor signalet sendes videre til ekstern controller/PLC.

Installation af HBX sensorer i filter / filterhuse

For korrekt funktionalitet af X-sensoren er det afgørende med en korrekt installation. Dette har vist sig at være udfordrende, når der svejses til/på rørbøjninger. Vi er derfor klar med en ny løsning hvor sensoren er integreret i filterhuse / ”strainer houses” monteret på sugeledningen. Funktionen er som på ”inline-sensoren”, men fordelen er, at filterlåget og sensorelementet kan afmonteres og rengøres om nødvendigt.

Product features

Measures the volumetric concentration of gas in a gas/liquid mixture
Balanced evaporator control to achieve semi-flooded operation with high heat transfer
Able to control an expansion valve directly with simultaneously analog 4-20mA output to a PLC
Can be used to optimize and control both DX systems and overfeed systems
Instant measurement and analog output
Can be used for all common refrigerants

Applications

 

HBX OVC

Optimum efficiency at all loads is obtain by measuring the Vapor Quality in the outlet of the evaporator and use the signal to change the height of the driving head as shown, lower level will minimize the liquid amount  in the evaporator and secure balanced and dynamic evaporation  during part load and thus optimum heat transfer.

The HBX-OVC-ST Vapor Quality control signal (cable out, 4-20mA) is connected to DI 3 (pin 3) on the HBSLC liquid level sensor and used to change the desired set value for the liquid level in the recirculation vessel/separator.

HOW TO ORDER
Vapor quality sensors come in numerous variants - all customized to the application. An order contains a mechanical part and an electronic part programmed to the order. Before ordering you need to consider:
1) The dimension and steel type for the mechanical part. (see table above)
2) The configuration and specification of the electronic part.
To make the right configuration of the sensor, please choose the functions and specifications you need for the electronic part:
Control function: (More than one function is possible)
☐ Analog output only 4-20 mA to PLC/main controller
☐ Control of stepper motor valve e.g. Carel E2V
☐ Control of PVM valve e.g. Danfoss AKV
☐ Control of motor valve e.g. Siemens MVS661 and Danfoss ICM
Refrigerant: (Only on selection)
☐ NH3
☐ CO2
☐ Other please specify
Application: (More than one function is possible)
☐ Direct expansion DX
☐ Overfeed system/flooded/pump circulation
☐ Compressor protection
☐ Leakage protection in ammonia CO2 cascade (ammonia carbamate)
☐ Other please specify
Other functions: (More than one function is possible)
☐ Remote setting of setpoint*
☐ USB cable
* Makes it possible to control the vapor quality (X) setpoint dynamically in the sensor used for controlling an expansion valve directly. The remote setting must be set from a PLC.

To order: Please fill out the HBX Vapor Quality Sensor Ordering Form and attach it in an e-mail to info@hbproducts.dk.
