HM8443

SIDE MOUNTED BRASS 4-BOLT REFRIGERANT LEVEL GAUGES RATED UP TO 450 PSI

Application
HM8443 series side mounted refrigerant level gauges are equipped with proportional voltage output or voltage output TwinSite® sender capsules with ranges of 1-2 volts, 1-6 volts or 0.5 to 4.5 volts output Hall Effect. They interface with various microprocessor based controllers now being used in commercial/supermarket applications for continuous, repeatable measurement of refrigerant levels and rates of loss.

General Information & Features
These gauges feature a 4-bolt brass head with integral mounting pads to accommodate the attachment of an electrical junction box. The junction boxes furnished with these gauges are not watertight and it is recommended that the connections inside boxes be made using waterproof connectors for rooftop and other outdoor service applications.

These gauges are typically furnished with neoprene gaskets which are compatible with several commonly used refrigerants and lubricants. Other gasket materials may be available.

The dials furnished with these gauges are magnetically driven. This means that the dials may be removed and replaced by removing two #6-32 screws and without disturbing the four gauge mounting bolts and releasing receiver contents.

The dials on gauges orignally equipped with direct read or direct read plus voltage output are typically interchangeable. In other words, a 1-2 volt output dial could be replaced with a 0.5 to 4.5 volt Hall Effect dial by removing only two #6-32 screws.

Hall Effect dials with 0.5 to 4.5 volt output introduce previously unavailable levels of noise free reliability and longevity. All dials with direct read only and direct read with voltage output are for use in both indoor and outdoor locations.
