Technical data: HBSR-HFC
The HBSR-HFC is a Level Switch designed for detecting common HFC, HFO, and CFC refrigerants in refrigeration systems. It is typically installed in refrigerant vessels, pump separators, economizers, or heat exchangers.
The Level Switch can detect all common refrigerants in gas. It is also possible to detect some refrigerants in oil if these two liquids don’t mix. This will not work for R1234ze, R1233zd, R125 and mixtures containing large amounts of these refrigerants.
Technical data: HBSR-SSR-1/IP
The HBSR-SSR-1/IP is a refrigerant switch designed for HFC, HFO, and CFC refrigerants, featuring a built-in heater to prevent condensation at low temperatures. This switch is ideal for use in freezers and outdoor environments.
Technical data: HBSR-HFC
HBSR-HFC is a level switch for detecting liquids e.g. HFC/HFO/CFC. It is calibrated so that it is unaffected by spray and foam. The sensor is designed in stainless steel and can be used in corrosive environments. The sensor is constructed to resist high pressure and low temperatures. The HBSR switch is only suitable for installation in steel tanks or steel pipes.
The switch must be supplied with 24 V DC through an Ex-barrier, which must be an approved and certifided galvanically isolated interface barrier placed outside the hazardous area. The switch is a 2-wire design with analog output which either will be 4 (no liquid detection) or 20 mA (liquid detection). The digital input shall be connected to the Ex-barrier. The Ex-barrier is not sccope of supply.
The sensor can be set-up for liquid type in the HB-Tool which can be downloaded from our web-page. See HB-Tool. It is as well possible to switch from NO to NC type in the HB-Tool. Diagnostic is as well a possibility with the tool. The programming must be carried out in an non hazardous area.
The sensor range include sensors for zone 0 and 1 according to ATEX/IECEx. The sensors can be used in device category 1G and temperature class T1...T6.
A 5 m cable with M12 plug type IEC61076-2-101 is included.
