Model: Series ODE

Hãng sản xuất: Ege-Elektronik

Thông số kỹ thuật:

The ODE 350 infrared sensor measures the energy transmitted from a body in the near infrared region (1 ... 3 µm). The energy taken up in this region of the spectrum is a measure of the temperature of the hot objekt. The device has four outputs which are independent of one another; two analogue outputs (current, voltage) and two outputs each with a switching threshold preselectable as either a relay change-over contact or as a semiconductor output. The required characteristic curve is preselected by a selector switch.

The device is operated using a fibre-optic cable, which can have temperature stability of up to 350 ºC. The standard cable can take up to 250 ºC. They have quick-release fastener provided with thread. To limit the angular field and increase sensitivity supplementary lenses for fibreoptic cable are available.

The given sensitivities refer to the use of a 1m long fibreoptic cable with a bundle diameter of 4mm during full illumination. Other fibre-optic cables and lenses yield correspondingly different minimum operating temperatures. As a rule, a fibre-optic cable with an additional length of 1m decreases the reaction sensitivity by 75 ºC.

Adjustment on switching detectors

Remove protection screw from the potentiometer.
The sensor must be mounted at its finally position.
Turn the screwdriver till the output switches (LED red).
Now the temperature is adjusted on which the infrared-detector responsed. The switching temperature can be increased if you turn the potentiometer clockwise.
Remount the protection screw.

Analogue temperature detection

The current output for the temperature is correct when:
The measured object has a homogeneous temperature and when its area has a minimum size of the sensor.s detection range (see path of the rays)
The emmision coefficient is Epsilon = 1 (black body).

At other cases the OD 100 GA measure a too low tempe rature. Therefore the OD 100 GA has a potentiometer for an adjustment.

Adjustment

Remove protection screw from the potentiometer.
The sensor must be mounted at is final position.
The actual temperature of the object must be known.
Turn the potentiometer clockwise until the output current correspond with the object temperature (see output characteristics).

Approval for safety applications
Sensors for personal security must have a qualifification approval according to EN 954-1 and must be labeled accordingly. Sensors that are not labeled must not be used for applications of this kind
