EL3001 Control Panel
Easy to install, complete monitoring system to detect early liquid leakage. Once leak is detected it responds within a few seconds and provides accurate leak location.
General Features
-
Maximum accumulated length of sensing cable
200m (Note: 192m for 4-20mA interface) -
Maximum accumulated length of jumper cable
300m -
Precision of leak location
+/- 1 metre or +/- 0.5% -
Display
LCD with backlight. 2 x 14 English characters -
Audible alarm
90dB max. buzzer with silencing button -
System reset
One single button for testing/resetting the system (hold down buzzer button for 6 seconds) -
Failsafe operation
Ability to operate in loop back operation and to detect liquid leakage during cable break -
Time to detect leak/cable break
4 seconds typically -
Liquid leak detection capability
Typically 20mm in length of liquid (e.g. tap water) in full contact with sensing cable. Leak sensitivity is adjustable. -
Multi-leak detection and location capability
-
Modbus TCP optional
-
Remote supervision by RS485 Modbus optional
-
Analog output 4-20mA interface optional
-
ASIC based digital location principle (patent pending) with inherent temperature stability, zero drift and very low power consumption
