Relative humidity
Acc. to IEC 60068-2-30 classification of environmental
conditions, natural factors, temperature and air humidity.
No effect under the following operating conditions: temperature
ranging from 25 to 55 °C (77 to 131 °F) and a relative air humidity
of 94 to 97 %.
Vibration
In accordance with IEC 60068-2-6 (03/95), grouping of devices
according to table C2 for general industry applications. No
additional effect on the following levels of vibration. Frequency
range 10 to 55 Hz; amplitude max. 0.15 mm.
Design
Field-mount housing made of cast aluminum per DIN 1725,
painted.
Paint coat thickness 80 µm. Lower section (RAL 7012), upper
section (RAL 9002). For dimensions, see Dimensions in the
Datasheet. Weight, approx. 3.3 kg.
Signal cable
Max. cable length between flowmeter sensor and transmitter is:
• 50 m for the standard design and versions with
automatic zero return, from DN 10 (3/8”) and from
20 µS/cm.
• 200 m for designs with preamplifier.
A 5 m signal cable is included with each flowmeter. If a cable
longer than 5 m is required, refer to the ordering information for
the sensor.
Coil supply cable
Is required to connect the flowmeter sensor to the transmitter.
For EMC reasons, the 2-wire cable is shielded. A 5 m cable is
included with each flowmeter. If a cable longer than 5 m is
required, refer to the ordering information for the sensor.
