TEMPERATURE RANGES
When selecting measuring transducer ranges, it is necessary to ensure that the
maximum temperatures permissible for sensor ⁄ housing are not exceeded !
Ambient temperature for measuring transducers: – 30 …+ 70 °C
Apparent ohmic resistance = see load resistance diagram
SUPPLY VOLTAGE
For operating voltage reverse polarity protection, a one-way rectifier or
reverse polarity protection diode is integrated in this device variant.
This internal one-way rectifier also allows operating 0 – 10 V devices on AC
supply voltage.
The output signal is to be tapped by a measuring instrument. Output voltage is
measured her against zero potential (O V) of the input voltage!
When this device is operated on DC supply voltage, the operating voltage input
UB+ is to be used for 15…36 V DC supply and UB – or GND for ground wire!
When several devices are supplied by one 24 V AC voltage supply, it is to be
ensured that all ”positive“ operating voltage input terminals (+) of the field
devices are connected with each other and all ”negative“ operating voltage
input terminals (–) (= reference potential) are connected together (in-phase
connection of field devices). All outputs of field devices must be referenced
to the same potential!
In case of reversed polarity at one field device, a supply voltage short-
circuit would be caused by that device. The consequential short-circuit
current flowing through this field device may cause damage to it.
Therefore, pay attention to correct wiring
Installation and Commissioning
Devices are to be connected under dead-voltage condition. Devices must only be
connected to safety extra-low voltage. Consequential damages caused by a fault
in this device are excluded from warranty or liability. These devices must be
installed and commissioned by authorised special-ists. The technical data and
connecting conditions shown on the device labels and in the mounting and
operating instructions delivered together with the device are exclusively
valid. Deviations from the catalogue representation are not explicitly
mentioned and are possible in terms of technical progress and continuous
improvement of our products. In case of any modifications made by the user,
all warranty claims are f orfeited. Operating this device close to other
devices that do not comply with EMC directives may influence functionality.
This device must not be used for monitoring applications, which serve the
purpose of protecting per-sons against hazards or injury, or as an EMERGENCY
STOP switch for systems or machinery, or for any other similar safety-relevant
purposes. Dimensions of housing or housing accessories may show slight toler-
ances on the specifications provided in these instructions. Modifications of
these records are not permitted.
In case of a complaint, only complete devices returned in original packing
will be accepted.
These instructions must be read before installation and commissioning and all
notes provided therein are to be regarded !
Our “General Terms and Conditions for Business“ together with the “General
Conditions for the Supply of Products and Services of the Electrical and E
lectronics Industry“ (ZVEI conditions) including supplementary clause
“Extended Retention of Title“ apply as the exclusive terms and conditions.
Notes regarding mechanical mounting and attachment:
Mounting shall take place while observing all relevant regulations and
standards applicable for the place of measurement
(e.g. such as welding instructions, etc.). Particularly the following shall be
regarded:
- VDE ⁄ VDI directive technical temperature measurements, measurement set – up for temperature measurements.
- The EMC directives must be adhered to.
- It is imperative to avoid parallel laying of current-carrying lines.
- We recommend to use shielded cables with the shielding being attached at one side to the DDC ⁄ PLC.
- If the sensor is used in refrigeration circuits, it must be insulated together with the housing to reduce the temperature potential between the device and the medium to a minimum and thus prevent condensation damage.
Before mounting, make sure that the existing thermometer‘s technical parameters comply with the actual conditions at the place of utilization, in particular in respect of:
- Measuring range
- Permissible maximum pressure, flow velocity
- Installation length, tube dimensions
- Oscillations, vibrations, shocks are to be avoided (< 0.5 g)
Attention! In any case, please observe the mechanical and thermal load
limits of protective tubes according to DIN 43763 respectively according to
specific S+S standards!
Notes regarding process connection of built-in sensors:
If possible, select material of protective tube to match the material of
piping or tank wall, in which the thermometer will be installed!
Maximum temperatures Tmax and maximum pressures pmax are as follows: for TH –
MS brass sleeves Tmax = +150 °C, pmax = 10 bar and for
TH – VA stainless steel sleeves (standard) Tmax = +400 °C, pmax = 40 bar.
Screw-in threads:
Ensure appropriate support of the gasket or sealing material when mounting!
Permissible tightening torque standard values for screw – in threads, are as
follows:
M 18 x 1.5; M 20 x 1.5; pipe thread G ½ ” : 50 Nm
M 27 x 2.0; pipe thread G ¾ ” : 100 Nm
Flange mounting:
In case of flange mounting, screws in the flange part must be equally
tightened. The lateral pressure screw must clamp securely, otherwise the
feeler shaft might slip through.
Welding sleeves:
Specific welding instructions shall be observed. On principle, unevenness or
the like that might influence the system‘s ”CIP ability“ must not develop at
welds.
For high-pressure lines, pressure test certifications and inspections are
required.
Notes on commissioning:
This device was calibrated, adjusted and tested under standardised conditions.
When operating under deviating conditions, we recommend performing an initial
manual adjustment on-site during commissioning and subsequently at regular
intervals.
Commissioning is mandatory and may only be performed by qualified personnel !
Permissible approach velocities (flow rates) for crosswise approached
protective tubes in water.
The approaching flow causes protective tube to vibrate. If specified approach
velocity is exceeded even by a marginal amount, a negative impact on the
protective tube’s service life may result (material fatigue). Discharge of
gases and pressure surges must be avoided as they have a negative influence on
the service life and may damage the protective tubes irreparably.
Please observe maximum permissible approach velocities
for stainless steel protective tubes 8 x 0.75 mm (1.4571) (see graph TH 08 –
VA ⁄ xx, TH 08 – VA ⁄ xx ⁄ 90) as well as for brass protective tubes 8 x 0.75
mm (see graph TH 08 – ms ⁄ xx) :
