3.5 Sensor head
Two different optical head types with a field of view of 10:1 or 2:1 are available. The spot sizes
at different measuring distances are shown in the drawings below; intermediate values have to
be interpolated. An additional close focus lens is available for the 10:1 head of series 510 instruments
(temperature resistant up to 85 °C). It can be used to generate a small spot size in a short distance.
3.5.1 Exchangeability of Sensor heads
Whether a sensor head can be used with a different electronic box is indicated by the identifier
"S1" on the sensor cable:
IN 500 (legacy product): optical heads 2:1 (S1 0xxx) and 10:1 (S1 1xxx) can be used with
any electronic box.
IN 510: optical heads 2:1 and 10:1 (both S1 0xxx) can be used with any electronic box.
IN 520: optical heads 2:1 and 10:1 (both S1 2xxx) can only be used with IN 520 electronic
boxes
When connecting a new sensor head to the electronic box, the respective 8-digit pin-code has to
be set (see section
3.6, Exchange of sensor head
).
Note:
The pyrometer can measure objects at any distance but the farther the distance, the
larger is the measuring area (spot size). The object has to be bigger than, or at least as big as the
spot size of the pyrometer in the measuring distance.
