The inco ming radiation is chopped with blades of a rotating mirror and converted to electrical signal. The electrical signal is amplified in the two-stag e programmable gain amplifier. The first amplifier (Receiver) has built in tempera ture compensation to correct temperature related variations of the photocell responsiveness. The Receiver has an automatic gain control. Gain adjustment range is sufficient for most applic ations. 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 Ci rcuit, 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 D etector, 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 4-2 0mA signal is proportional to radiation from the hot object and can be used to monitor proc ess temperature. The HMD-3000-D has digital output of threshold, gain and the temp erature inside the sensor in degrees C Automatic Gain Control (AGC) allows the sensor to c hoose the best gain setting so that the energy of the signal is always between 3000mV and 8 000mV. 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 s ize targets, or different temperatures, or a combination of conditions. C HOICE 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. HMD-3000 –D PbS
