Seikom RLSW8AL V2 LCD Bedienungsanleitung Seite 5

The RLWS8AL V2 is a micro controller based airflow monitor which watches gaseous flows from 0.5m/s to
10/30m/s. It provides a 4-20mA as well as a 0-10V-DC output. Also it provides a 0-10V-DC output based on the
temperature.

Reference terms and conditions: Inlet way > 10xDN, outlet way > 5DN laminar flow: ait at 0°C and 1.013bar.
Cable length with separate sensor is 2.5m.
*Different immersions depths are available (50/130/165mm). High temperature sensors (up to 350°C) are also
available.

Terms of installation:
To avoid malfunction you need to follow these facts:
- the sensors tip need to be mounted in the middle of the duct
- the sensor elements need to be fully circulated around by the media
- the mark on the sensor needs to be exactly fronted to the flow
- in vertical tube the flow directions might be upwards
- maintain 5xD of free inlet way and 3xD of outlet way
- the sensor is to be mounted only with its hexagonal bolt
- the flow monitor is independent of its mounting position
Attention:
Sensor and monitoring device are calibrated to each other! Change of one part leads to
malfunction! The cable's length may not be changed. If you need longer or shorter cable lengths
feel free to ask our consultant.
Cleaning the sensor:
The airflow sensor contains a sensor element which is sensitivity to mechanical loading and which must not be
touched with hard and pointed objects. Any cleaning that may be necessary is possible in water (also with addition of
detergents). Let the unit drip off and dry renewed start-up.
