Temperature sensor model PT-1000

CHARACTERISTICS

Measuring range :
-50 à +300°C

Accuracy :
>0,1°C

Resolution :
0,01°C

Resistance :
1000 Ω ± 0,1 à 0°C

APPLICATIONS PPLICATIONS
The temperature sensor models PT 1000 serves to measure the Diameter :
relative temperature, as much in the environment close to the work as 6 mm
in the civil engineering structure of concrete or on the metallic
elements of the work. Length :
The PT 1000 sensor is used for the long-term control of buildings and 50 mm (standard)
works over which the temperature variations always have a direct
influence modifying the mechanics "dilatation". This “Temperature” Class :
parameter value of the variations of the temperature is an essential A
information. In order to compare the reality of the events with the
predictive calculations and/or to allow a correlation with the other
physical parameters measured as the deformations of the structures or
the hydrostatic pressure influencing the density of the water.
DESCRIPTIF ESCRIPTION
D Étanchéité :
The temperature sensor Pt 1000 is made of a resistance in fitted deck IP68
wire into a tube of protection in stainless steel sheathed inside by an
insulating material in quartz.
The value of the resistance in platinum is 1000 Ω in 0°C. In a known Cable :
and experimental way the variation of resistance is linear and 4 conductors
continuous according to the temperature in the -20°C + 80 °C range
of acceptable use for the most part of the works of civil engineering. Options :
This type of industrial sensor allows to obtain a big precision on all its Armored cable
area of the measure of the temperature. Sensor chain
On the 4 wire sensors, a reference resistance allows to know exactly End of cable plug
the generated current. The measure is then made by using this source Other length of sensor
of stable current known, and by measuring the tension in four borders
of the sensor and by comparing it with the reference value of1000 Ω . Accessories :
The read tension is directly proportional in the variation of the value of Reaout unit
the resistance of the probe.
The reading on 4 wires allows to free itself from the length of the cable
by direct compensation of the variation of resistance of the cable, and
so to keep a big precision of measure.
