During work on and with the device the required personal protective equipment must always be worn. Appropriate use B63-48, B63-32 are overvoltage arresters in two-wire technology for installation in VEGA level and pressure sensors. You can find detailed information on the application range in chapter "Product description". Warning about incorrect use Inappropriate or incorrect use of the instrument can give rise to application-specific hazards, e.g. vessel overfill or damage to system...
That is why we have introduced an environment management system with the goal of continuously improving company environmental pro- tection. The environment management system is certified according to DIN EN ISO 14001. Please help us fulfill this obligation by observing the environmental instructions in this manual: • Chapter "Packaging, transport and storage" • Chapter "Disposal" Overvoltage arresters • B63-48, B63-32...
Principle of operation Application area The overvoltage arresters B63-48, B63-32 are completely enclosed in a stainless steel housing. They can be used for VEGA level and pres- sure sensors in two-wire technology. • Type B63-48 for 4 … 20 mA/HART sensors •...
Protected against solar radiation • Avoiding mechanical shock and vibration • Storage and transport Storage and transport temperature see chapter "Supplement - temperature Technical data - Ambient conditions" • Relative humidity 20 … 85 % Overvoltage arresters • B63-48, B63-32...
No further assembly is necessary. Caution: B63-48, B63-32 overvoltage arresters must not be used in a corrosive environment. The thread on the overvoltage arrester must correspond to the thread on the sensor housing. In order to maintain the enclosure rating of the sensor, PTFE gasket strip must be used.
The B63-48, B63-32 exhibit a voltage resistance of 0.5 kV for one minute in the signal circuit with respect to the stainless steel housing, but not with respect to the green/yellow cable in the sensor circuit.
