3.5 Electronics

The MCT contains the following electronic components:
o Power Supply, a 90-260 volt auto selection supply providing DC power to operate the sensor.
o Main PCB, containing pre-amplifiers, detector controller, central processing system, analog and
serial communications.

4.0 Installation

4. 1 Sitting the sensor

The sensor is capable of operating at any orientation provided the light beam can reflect from the
surface of the product.

4.2 Vibration

The sensor mounting support and any items in contact with the sensor should be free from excessive
vibration.

4.3 Strong Light

Strong infrared light or direct sunlight should not be allowed to fall on the sensor window or erroneous
reading may occur.

4.4 Temperature

The sensor is designed to give satisfactory measurements within a temperature range of 32 to 120 deg. F
(0 to 50 deg. C).
4.5 Humidity and Dust – Window Air Purge
The head should be kept clear of excess humidity. It is important to prevent condensation on the sight
window. Normal atmospheric dust will not affect the sensor reading but similar to humidity,
accumulation of dust on the window will impair the sensor's operation. The air purge attachment fitted
to the sensor window requires a 1/4" (6mm) tube with a supply of clean oil free dry air at a pressure not
exceeding 10 psi. at approximately 2 liters per minute.
