HBProducts | Liquid Level Switches| IECEx & ATEx Zone 0 &1 | Ammonia, Water & Alcohol
Technical data: HBSR
HBSR is a level switch for detecting liquids. It is calibrated in such a way that splash water and foaming cannot harm it. The sensor is made of stainless steel and can therefore also be used in corrosive environments. It withstands high pressures and low temperatures. The HBSR may only be used in steel tanks or steel pipes.
The switch must be supplied with 24 V DC power across an Ex barrier. This barrier must be an approved and certified galvanically isolated interface barrier located outside the hazardous area. The switch is a 2-wire version with an analog output with 4 mA (no liquid detection) and 20 mA (liquid detection). The digital input must be connected to the Ex barrier. The Ex barrier is not included.
The sensor can be adapted to the respective liquid type using our HB tool, which you can download from our website. See HB Tool. In addition, the HB Tool can also be used to switch between NC and closing contacts. Diagnoses can also be carried out with the tool. Programming must be carried out outside the danger zone.
According to ATEX/IECEx, the sensor range includes sensors for zones 0 and 1. The sensors can be used in device category 1G and temperature class T1... T6.
A 5 m long cable with an M12 connector of type IEC61076-2-101 is included in the scope of delivery.

Intrinsically Safe design:
Intrinsically safe sensors (IS) are designed to function with such a low current and voltage and are wired that there can be no ignition of flammable materials. By limiting the energy present in a certain hazardous area, the electrical appliances can also operate safely surrounded by harmful gas mixtures.
The measuring principle and the influence of the dielectric constant:
Capacitors are designed with minimum two conductors, where one of them is electric isolated. The dielectric constant are key for operation of capacitors, the capacity size is measured in pF.
Dielectric constant (Relative permittivity) is a unique value on a scale of 1 to 100. The value can be seen as a media’s DNA, because it`s unique and related to the molecular structure and polarization.
The Dielectric Constant is always greater than or equal to 1. The larger the dielectric constant, the more charge can be stored (like a battery).
The dielectric constant changes with temperature and pressure, the sensor comes with automatic temperature compensation calibrated/adapted to the measured media.
