1 Introduction
The level switches Nivotemp NT64 and Nivovent NV74 are designed for level- and temperature control in
fluid systems.
Depending on the model, the following configurations are available:

Up to four switching outputs for level control or

Up to three switching outputs for level control plus one switching output for temperature control or

Up to three switching outputs plus Pt100 (RTD) or

Up to three switching outputs for level control plus one analogue output for temperature control
The following options are available:

SSR stilling tube with support ring: The stilling tube is made of the same material as the immersion
tube (MS/VA).
With series Nivovent this option includes an additional filling adapter (option BFA).
The Nivovent series is equipped with an air breather filter with the following options:

VS visual clogging indicator for the air breather filter: analogue underpressure indicator, display
range 0.35 bar.

BFA filling adapter incl. ribbed flange with sieve insert: this option allows that small oil quantities
can be filled via the breather housing. Therefore the corresponding housing is equipped in that
version.
