Product description
The level switch has 2 separate switching relays with a potential-free changeover contact, for switching on or off.
Can directly control a water pump or valve for automatic control of liquid level.
The level switch is equipped with a third sensor input, intended as an overflow alarm or for automatic shutdown in emergency situations.
Applications
Automatic refilling and draining
This level switch can automatically fill or empty a reservoir by controlling a valve (solenoid valve) or a water pump.
The level switch can monitor the water level in a basin (pond, swimming pool, aquarium, basement, well). It makes no difference whether the basin is made of metal, plastic or concrete.
Monitoring of MAX or MIN level
Using an additional sensor, you can use the second relay contact for an alarm when the level is too high or too low.
The third sensor is separate from the sensors for MIN and MAX. It may be placed at any desired height. Tip: with a GSM detector, you can receive an overflow alarm on your phone.
The switching contact can control an external acoustic or optical alarm for up to 10 minutes (adjustable). See below under Related Products.
Required: 2 or 3 water sensors
-model: water detector-sensor
-type: conduction
-Connection cable: length 10 m\
The connecting cables of the water sensors may be extended to a total of 50 m, with signal cable.
With the mounting height of the MIN and MAX sensors you determine the switching points between which the water level is controlled.
Tip 1: A third water sensor is required to use the overflow alarm.
Tip 2: Order the required number of water sensors via selection box at number.
Tip 3: Also suitable for other sensors. Choose the option 'without sensors' and then order 2 or 3 pieces Water-sensor-RVS or float switches.
