RedBin-P ATEX Pressure / Differential Pressure Switch
The RedBin-P-… pressure switch generation from 5…5000 Pa (acc. to type) is a revolution for differential pressure switches in HVAC systems, in chemical, pharmaceutical, industrial and offshore/onshore plants, for use in hazardous areas zone 2 (gas) and zone 22 (dust).
Description
Highest protection class (ATEX) and IP66 protection, small dimensions, universal functions and technical data guarantee safe operation even under difficult environmental conditions. All sensors are programmable on site without any additional tools.
– Power supply 24 VAC/DC
– Potential free switching contact output
– Adjustable switching threshold, hysteresis and start-up bypass time
– Adjustable switch activation delay (acc. to type)
– Integrated Ex-e terminal box
– No addional Ex-i module required
– No intrinsically safe wiring/installation between panel and sensor required
– No intrinsically safe wiring/installation and no space in the panel required
– Optional second switching output (acc. to type)
– Display with backlight, can be switched off
– Password locking
– Compact design and small dimension
All pressure switches require a 24 VAC/DC power supply. The electrical wiring must be realized via the integrated Ex terminal box acc. to ATEX.
