RLS-1000德国wika浮球开关

德国wika授权代理 RLS-1000浮球液位开关  顶装浮球液位开关
RLS-1000是一款坚固耐用、可靠且廉价高的浮球开关。由于在机械制造行业中，进行对液位监测、运行保护和溢流保护时，对成本控制较为严格，
因此浮球开关是许多工厂的理想解决方案。RLS-1000通过多达4个确定的开关点上的永磁体和无摩擦干簧触点，可靠监测罐体内的水、油、柴油或其他液体介质的液位。该产品可在-30至+150℃[-22至+302℃]的中温范围内使用。

该紧凑型浮球开关安装简单、方便、快速，因为它不需要在安装过程中进行校准或设置。这大大提高了操作的便利性，特别是在空间受限的安装情况下。此外，由于其坚固耐用的特性，以及抗振动和抗冲击，该产品的维护成本较低。

RLS-1000浮球液位开关主要参数
Float switch, model RLS-1000
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 1)
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 ∅ = 18 mm [0.7 in], 22 mm [0.9 in], 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 2) Floats with outer diameter ∅ D = 44 mm [1.7 in], 52 mm [2.0 in]
