Liquid Level Control

 

Refrigerant  Float Switch

parker refrigeration Clark Johnson Co

HBLT capacitive liquid level transmitters are used to measure liquid levels in refrigerant vessels, receivers, accumulators, or other similar pressure vessels.

  Product Overview

     Specification

     CAD

The HBLT-A1 level probe transmitter provides easy installation and calibration, and is adaptable to suit the actual application of the product. The electronic insert of the probe converts the measured change in capacitance, 4 to 20 mA, of the liquid to a signal in proportion to the level making it possible to control and/or regulate the liquid level when used in conjunction with a controller. Capacitive level measurement is based on the change in capacitance of the capacitor due to the change in the level. A capacitor is formed when a level sensing electrode is installed in a vessel. The metal rod/electrode acts as one plate of the capacitor and the reference tube acts as the other plate. As level rises, the air or gas normally surrounding the electrode is displaced by material having a different dielectric constant. A change in the value of the capacitor takes place because the dielectric between the electrodes has changed. Capacitance instruments detect this change and convert it into a proportional output signal.

 

Markets:

 

• Industrial Refrigeration

 

Features and Benefits:

 

• Suitable for ammonia, CO2 and halocarbon refrigerants

•  “Service Friendly”

    - Split design makes it easy to install and perform diagnostic

    - Electronic head and probe can be separated without emptying the vessel

    - Electronic parts can easily be disconnected with 2 small screws

• “Proven and Reliable Design”

    - Optional LED bargraph for indication of liquid level

    - Damping of output signal available

    - Process signal output of 4-20 mA

• “Improved Calibration”

    - Offering simple calibration function and the possibility to reduce the effect of liquid leaks

    - “Plug and Play” no calibration required when installed on ammonia systems

    - Range/signal output can be adapted to suit the actual application

 

Application:

 

• Refrigerant Vessels

• Receivers

• Accumulators

• Other similar pressure vessels
