Gestra NRS1-53 Low-Level Alarm Switch 24VDC
The level switch NRS 1-53, when used in conjunction with level electrodes NRG 16-.. and ER 5. is used as a limit switch, (for example) a water level limiter in steam boilers and within (pressurized) hot-water installations. The level switch detects and indicates two low water levels (MIN 1, MIN 2).

The level switch can work with the following level electrodes: NRG 10-52, NRG 16-52, NRG 16-4 and ER 5.-1.

The level switch NRS 1-53 operates on the conductive measuring principle using the electrical conductivity of the water for signalling the water level. The level switch is designed for different electrical conductivities and for connecting two Level-Electrodes

The length of the associated electrode rod determines switch points for both MIN 1 and MIN 2 water levels.

The level switch detects when the MIN1/MIN 2 water levels are reached. The detection occurs when the corresponding electrode rods are exposed. After the de-energizing delay has elapsed, the MIN 1 / MIN 2 output contact is switched. At the same time, the MIN 1 / MIN 2 LED changes from green to red.

When functioning as a water level limiter, the safety circuit for the heating is set to open by the output contacts.

The disconnection of the heating is interlocked in the external safety circuit and can only be deactivated when the electrode rods enter the water again.

A MIN 1 / MIN 2 simulation can occur by pressing the "Test" button.
