MEASUREMENT & MONITORING
THERE NEED BE ONLY ONE!
RHEINTACHO
ONE SENSOR, TWO SIGNALS: ROTATIONAL SPEED
SENSOR WITH AN INTEGRATED TEMPERATURE SENSOR
M8-rotational speed sensors from
RHEINTACHO now include two important
features including not only the monitoring
and measuring of rotational speed but
also detect temperature additionally. This
is a trend setting move of RHEINTACHO to
integrate temperature recording alongside
of rotational speed measurement.
The sensor offers features such as
temperature detection, standstill detection
(0 Hz) and of course speed measurement. It
is easy to set up with no alignment required.
It can be used in wide temperature ranges as
well as a wide range of frequencies.
And all of this in just one small sensor!
conditions. In hydraulic applications, the
homogenizing effect is supported by
hydraulic fluid. In electro-motors, the use of
a temperature signal side in a speed sensor
requires significantly more adaptation as
the installation position has very different
ambient conditions from the common
installation position of the temperature
sensor.
The indisputable advantage of being able
to call up several parameters at the same
time is more present than ever. The cost
advantages are complex and are not only
limited to the installation costs, but also do
not include requiring further sensor access
gates, a very obvious advantage.
For recording temperature, an NTC
temperature element with the following
specifications is used: ± 1.5 °C above the
total operating range, NTC 4.7 kOhm, ±1 %
@ R25; B25/85-value: 3830 K. The other benefits:
RHEINTACHO has announced that further
sensor series are now being developed in
addition to the M8. Installation effort: complete elimination of
one installation process.
Depending on the application, the
evaluation of the temperature signal has
to be adapted to the differing installation
Rheintacho explains: “At first glance, the idea
is captivating and logical, as is every good
idea. However, as usual, we can certainly
say that the problem was in the detail.
Especially when considering the realization
of the series product, many challenges had
to be overcome. But now, the products are
available, and sales is developing above our
expectations. We are sure further sensor
series will follow.”
Material costs: one complete sensor with
its own electronics, own housing and
connection interface are saved.
Design simplification: Saving an additional
sensor access including all possible side
effects such as improving design freedom
and reducing leakage opportunity.
