Switching Head A-V3   For devices VM-

● II 2G Ex d IIC T6 Gb

Switching head with pressure-resistant encapsulation and ATEX approval for the VM range of devices.

Switch              : micro switch

Handling and operation
Note

● Cable lengths max. 5 m.
● It must be ensured that the values given for voltage, current,
and power are not exceeded.
● When switched on, a load must be connected in series.
● The electrical details apply to ohmic loads.
Capacitive, inductive and lamp loads must be operated using a
protective circuit.

Adjustment

To adjust the switching point, the fixing screw for the switching
head must be loosened. The switching head can then be rotated.
Turning to the right increases the switching point, and vice-versa.
Then retighten the fixing screw.

Le débitmètre en ligne est basé sur le principe de mesure du débit massique thermique et convient parfaitement aux mesures de débit dans les conduites DN15 à DN25. Il permet de mesurer la consommation d'air comprimé (éventuellement aussi d'azote, de CO2, d'oxygène, d'hélium ou d'autres gaz non corrosifs et incombustibles).

Flow Transmitter / Switch OMNI-RT 

● Universal turbine flow sensor

● Analog output, two switching outputs

● Clear, easily legible, illuminated LCD display

● Modifiable units in the display

● Designed for industrial use

● Small, compact construction

● Simple installation

Characteristics :

A turbine acts as the primary sensor; its rotational speed is proportional to the flow rate. The rotational speed is detected by means of pre-tensioned Hall sensors, i.e. there are no magnets in the flow space. The OMNI transducer located on the sensor has a backlit graphics LCD display which is very easy to read, both in the dark and in bright sunlight. 

Flow Transmitter LABO-RT-I / U / F / C 

● High precision

● No magnetic components in the flow space

● High pressure resistance

● 0..10 V, 4..20 mA , frequency/pulse output, completely configurable

Characteristics :

A turbine acts as the primary sensor; its rotational speed is proportional to the flow rate. The rotational speed is detected by means of pre-tensioned Hall sensors, i.e. there are no magnets in the flow space. The LABO-RT electronics make various output signals available:

● Analog signal 0/4..20 mA (LABO-RT-I)

● Analog signal 0/2..10 V (LABO-RT-U)

● Frequency signal (LABO-RT-F) or

● Value signal pulse / x litres (LABO-RT-C)

A model with switching output is also available (see separate datasheet).

If desired, the range end value can be set to the currently existing flow using "teaching"

Flow Transmitter /Switch FLEX-RT

● Versatile turbine flow sensor
● Switching output and analog output (4..20 mA / 0..10 V)
● Top quality materials
● Designed for industrial use
● Ingress protection IP 67
● Infinitely adjustably rotatable cable outlet for clean
alignment
● Small, compact construction
● Very simple installation

Characteristics :

A turbine acts as the primary sensor; its rotational speed is
proportional to the flow rate. The rotational speed is detected by
means of a biased Hall sensors, i.e. there are no magnets in the
flow space.
The FLEX transducer located on the sensor has an analog output
(4..20 mA or 0..10 V) and a switching output, which can be
configured as a limit switch for monitoring minimal or maximal, or
as a frequency output.

Flow Switch LABO-RT-S

● Very short response time
● High precision
● No magnetic components in the flow space
● High pressure resistance

Characteristics

A turbine acts as the primary sensor; its rotational speed is
proportional to the flow rate. The rotational speed is detected by
means of pre-tensioned Hall sensors, i.e. there are no magnets in
the flow space.
The integrated converter / counter make available an electronic
switching output (push-pull) with adjustable characteristics
(minimum/maximum) and hysteresis, which responds when an
adjustable limit is fallen short of or exceeded.
The switching value can be set to the currently existing flow using
"teaching".
Models with analog or pulse output are also available.

Le contrôleur de débit à palettes en plastique a un axe en titane qui assure une roulement à faible frottement. La palette suit le débit contre la force de deux aimants jouant le rôle de ressorts. L'aimant à palette active également un contact Reed positionné à l'extérieur de la chambre d'écoulement.
