NRGT 26-2 and NRGT 26-2s level transmitters can be used to continually measure the water level in pressurised steam and hot-water plants, or in condensate and feedwater tanks. The calibrated measuring range from 0 % to 100 % constitutes the linear profile of the 4-20 mA current output. The transmitter’s secure 4-20 mA actual value output (SIL 2) can be used with a suitable level controller, as a water level controller with MIN/MAX alarm, for example. The level transmitters are installed on the inside of pressurised steam plants, tanks or feed lines of pressurised hot-water plants. A protective tube provided on site ensures reliable function. A capacitive NRGT 26-2 or NRGT 26-2s level transmitter and a conductive NRG 1x-60 or NRG 1x-61 level electrodecan be installed in the same protective tube or level pot.
Transmitter function
The transmitter function is the ability of the electrode to provide a scalable measuring range on the 4-20 mA current output interface and to make this available to one or more recipients for analysis. Conductivity transmitters do not have any controlling or limiting functions.
