Meas. range 2
Temperature: -5.0...140.0 °C (resolution 0.1°C or 0.1°F, NTC10k)
Attention: Consider application range of measuring cell: 0..80°C
Accuracy:
(at nominal temperature = 25°C)
Measuring:
conductivity:
±0,5% of measured value ±0,3 FS
temperature:
±0.1°C of measured value ±1 Digit
Add. output signal:
±0.2 % FS
Measuring cell:
4 electrode measuring cell with temperature sensor NTC10k,
7 pole connector
Cell constant K: 0.45..0.65, determined and adjusted ex works
Temperature compensation:
non linear function, linear function (coefficient configurable) or none
Min-/Max-Value Memory:
Min and max measured values are stored
Output signal:
refer to type plate, freely scaleable
Scaling:
By entering display values for 4mA (or 0V) and 20mA (or 1V/10V) output
Connection:
4 - 20 mA (2-wire) – output signal electrically isolated
for option AV01, AV10:
0 - 1 (10) V (3-wire) – output signal electrically isolated
Auxiliary energy:
(supply voltage)
Uv = 12 - 30 V DC (4-20mA)
Uv = 12 - 30 V DC, max. 10mA (0-1V)
Uv = 18 - 30 V DC, max. 10mA (0-10V)
or refer to type plate
Reverse voltage protection:
50V permanent
Perm. impedance
(at 4-20mA)
:
RA(Ohm) < ( (Uv - 12V) / 0.02A )
Example: for Uv = 18V: RA < (18V - 12V) / 0.02A => RA < 300 Ohm
Permissible load
(at 0-...V)
:
RL(Ohm) > 3000 Ohm
Adjusting:
via keypress. Conductivity by editing cell constant K (CELL)
Temperature by offset and scale.
Display:
approx. 10 mm high, 4-digit LCD-display
Ambient conditions for electronics:
Nominal temperature:
25°C
Operating condition:
-25 to 50°C, 0 to 95 %RH (non-condensing)
Storage temperature:
-25 to 70°C
Ambient of standard measuring cell
-5 to 80°C (short time up to 100°C)
Housing:
ABS (IP65)
Dimensions:
82 x 80 x 55 mm (without elbow-type plug and sensor tube)
Mounting:
With holes for wall mounting (in housing - accessible after cover has been removed).
Mounting distance:
50 x 70mm, max. shaft diameter of mounting screws is 4 mm.
Electrical connection:
elbow-type plug conforming to DIN 43650 (IP65),
max. wire cross section: 1.5 mm², wire/cable diameter from 4.5 to 7 mm
EMC:
In accordance with EA1 +A2 (appendix A, class B), additional errors: < 1% FS.
When connecting long leads adequate measures against voltage surges have to be taken.
The electrode connections have to be protected sufficiently against ESD pulses, if the
device is used in areas with risk of ESD.
