The LA1S sensor with its Ø 12 mm glass body can be mounted inside a GL connection of a F...-...-D
universal filter or in the LS flow chamber. The LA25S sensor has got a 1/4" special male connector for
mounting inside the FSS...-D universal filter or for mounting inside a 8 mm tube using a special union
tee connector LS25 .
With the universal filters and the flow chamber, the gas inlet and gas outlet can be rotated 180 degrees
during installation.
The corresponding
M&C controller electronics are available in 2 mounting variants for wall mounting
LA1.1 and rail mounting LA1.4 .
A line break control system is integrated for safe operation. One LED each is provided for operation and
fault indication, as well as two potential-free changeover contacts in "Safety First" circuit for safe alarm
signalling. The electronic controller
LA1... contain an alarm hold function and an alarm reset which can
be activated or deactivated on request. They are not activated on delivery.
By using one of the contacts, a pump or a solenoid valve in the gas conditioning system can be switched
directly and the second contact can be used as a status alarm.
The switching point of the electronic controller
LA1... is adjustable via a potentiometer. A standard
adjustment to a conductivity of 100µS/cm is set at the factory.
A T T E N T I O N ! Use the special electronic controller ER142 Exi (without line break control)
(Part No. 03E2009(a)) only for the intrinsically safe supply of the sensor LA1
or LA25 of the old series located in the EX area.
When used with the new sensors LA1S and LA25S, there is no explosion
protection.
