7.3 Tips on Electromagnetic Compatibility (EMC)
Keep all connecting cables as short as possible.
With cable routes longer than 30 m or with strong electromagnetic disturbance along the cable route
between sensor and evaluation unit, the use of a double-shielded cable is recommended: to do this
lay inner shielding to one side of the evaluation unit and lay outer shielding on both sides over a large
area with low-impedance connection on the sensor and evaluation unit or on the control cabinet
Do not loop the cable!
Lay free strands at both ends on protection potential!
Lay cables as close to ground as possible, as for example side panels, mounting plates or steel
girders.
When using frequency converters there is a risk of interference by HF transient emissions.
Therefore, decouple the power input of the frequency converter via an interference filter
against active transient emissions. This also increases the passive interference resistance of the equip-
ment.
Use only shielded motor cables with shield support on both sides between motors and converters.
spatially separate cables which emit interference from measuring lines and evaluation units. If
necessary, lay measuring lines in a metallic tubular cable protection.
Ensure large area and low resistance connection of metallic parts in control cabinets, such as
subracks with control electronics or subplates.
Relays, contactors and electro valves in the same electric circuit, are to be wired with spark
Fig. 2: LCD display connection with cover open

_________________________________________________________________________________________________
________________________________________________________________________________________
12/18 U398_UVATP_B_e_221219
quenching combinations or surge-limiting components.
Lay the shielding of analog signal lines on one side only –preferably on the evaluation unit - and low
resistive. Twist unshielded lines to counteract balanced interference to source terminals.
Lay the shielding of digital signal lines on both sides across a wide area. In the case of potential
differences between these points it is advisable to lay a separate equipotential bonding conductor.
Preferably provide shielded connector for connections to connector cable separation points.
If using terminals, these should be in a HF-shielded housing, in which EMC-compatible cable bushes
should be used. Connect outer shielding of the connector cables to the cable bush.
7.4 Connection Cable
For connecting between sensor and separate transducer UVATP LiYCY cable with simple copper braiding
screen can be used if the cable path is short and there is marginal electromagnetic interference. Over
longer distances or with a high rate of electromagnetic interference, a double-screened cable of type
LiYCY-CY should be used.
VA sensor 3 x 0.25 mm²
Max. permissible conductor resistance per strand is 15 Ohm.
Conductor resistances for finely stranded conductors:
approx. 79 Ohm/km with wire cross section 0.25 mm2
approx. 39 Ohm/km with wire cross section 0.50 mm2
approx. 26 Ohm/km with wire cross section 0.75 mm2
8Functional Description
UVATP transducers are for mass flow output or standard flow rate output by measuring the actual flow
rate, the operating temperature and the absolute pressure.
The signal frequency coming from the flow sensor and proportional to the actual flow rate signal is con-
verted into a linear analog output signal 4-20 mA or 0-10 V taking temperature and absolute pressure
into account (see under 6.5 Electrical Data).
The analog terminal value is configurable.
Current output : 4 ... 20 mA = 0 ... x kg/h (0 … x Nm³/h)
alternatively:
Voltage output : 0 ... 10 V = 0 ... x kg/h (0 … x Nm³/h)
The relay output (normally open contact) can be configured for 1 of 2 different functions:
1. as limit value for the mass flow (standard flow rate):
mass flow (NV/t) < or = limit value : relay contact in rest position
mass flow (NV/t) > limit value : relay contact in operating position
2. as quantity pulse for the quantity measurement:
max. pulse repetition frequency 1 Hz per mass unit (standard flow rate unit), configurable,
e.g. 1 pulse per 1, 10 or 100 kg, pulse duration 0.5
In the case of measuring systems with a maximum mass flow rate up to 6500 kg/h, the output in the dis-
play and at the analog output follows with a decimal place (e.g. 6489.7 kg/h) and with higher maxi-mum
mass flow rate without a decimal place (e.g. 24585 kg/h).

17 Calibration
The UVATP has an excellent long-term stability. However, it makes sense to have it calibrated at regular
intervals. The time lapse between calibrations depends on the individual operating conditions and the tol-
erable measurement error. Therefore, as a precautionary measure, shorter calibration cycles are recom-
mended in the beginning. As a general rule and under 'normal' operating conditions we suggest a cycle of
approx. 3 - 5 years.
The transducer must be returned to the manufacturer for calibration (see under 19 Returns)
