Float Switch - RLS-1000
Brand: WIKA Instruments Ltd.The model RLS-1000 float switch has been developed for monitoring the level of liquids. The stainless steel used is suitable for a multitude of media, such as, for example, oil, water, diesel and refrigerants.
Features- Media compatibility: Oil, water, diesel, refrigerants and other liquids.
- Permissible medium temperature range: -30 to150 °C.
- (-22 to 302 °F).
- Up to 4 switching outputs freely definable as normally.
- open, normally closed or change-over contact.
- Potential-free switching reed contacts.
Specifications
Measuring Principle
- Potential-free switching reed contacts are triggered by a magnet in the float.
Guide Tube Length L
- 60 ... 1,500 mm [2.5 ... 59 in], other lengths on request
Output Signal
- Up to 4 switch points, depending on the electrical connection: SP1, SP2, SP3, SP4
Switching Function
- Alternatively normally open (NO), normally closed (NC) or change-over (SPDT) contact - on rising level
Switch Position
- Specified in mm, starting from the upper sealing face (SP1 ... SP4)
- At the end of the guide tube ≈ 45 mm [≈ 1.8 in] cannot be used for switch positions.
Distance Between Switch Points
- Minimum distance SP1 to the upper sealing face: 50 mm [2.0 in]
- Minimum distance between the switch points:
- 50 mm [2.0 in], for floats with outer ∅ = 44 mm [1.7 in], 52 mm [2.0 in]
- 30 mm [1.2 in], for floats with outer ∅ = 25 mm [1.0 in], 30 mm [1.2 in]
- Minimum distance with 3 switch points: 80 mm [3.1 in], either between SP1 and SP2 or SP2 and SP3
- Minimum distance with 4 switch points: 80 mm [3.1 in], between SP2 and SP3
Switching Power
- Normally closed: DC 100 V; 10 W; 0.5 A
