DESCRIPTION:

The HMD-3000-D Hot Metal Detector uses an infrared sensitive PbS photocell to detect radiation

from hot objects starting as low as 150°C. The incoming radiation is chopped with blades of a

rotating mirror and converted to electrical signal. The electrical signal is amplified in the two-stage

programmable gain amplifier.

• The first amplifier (Receiver) has built in temperature compensation to correct temperature

related variations of the photocell responsiveness. The Receiver has an automatic gain control.

Gain adjustment range is sufficient for most applications. The adjustable aperture at the front of

the hood can reduce any additional radiation level. (Double Diaphragm option).

• The amplified signal is fed to the Discriminator Circuit, which compares it with the preset

threshold voltage and activates the relay and opto-coupled MOSFET when signal exceeds the

threshold.

• The amplifier output is also fed to the Amplitude Detector, which produces DC voltage

proportional to the amplitude of the chopped signal. This voltage drives the 4-20mA converter,

which produces the HMD current loop signal. The 4-20mA signal is proportional to radiation

from the hot object and can be used to monitor process temperature.

• The HMD-3000-D has digital output of threshold, gain and the temperature inside the sensor in

degrees C

• Automatic Gain Control (AGC) allows the sensor to choose the best gain setting so that the

energy of the signal is always between 3000mV and 8000mV. This means that it is never

saturated (over 9969mV) and never less than 3-times the threshold. This feature is particularly

good for intermittent steam conditions, different size targets, or different temperatures, or a

combination of conditions.

CHOICE OF PHOTOCELL: The HMD 3000-D is designed to

use a lead sulfide (PbS) photocell.

Lead sulfide has superior hot metal

detection capabilities. The output

level is sufficient to provide

reliable detection even with

product temperatures as low as

150°C and is continuous when the

hot product is within the viewing

field.
