SISTEC 1230-90-2000-D Detector Card Digital Density Gauge

The SISTEC 1230-90-2000-D Detector Card is the DDG Transmitter PCB (PCB8762) that forms the transmitter half of SIStec’s detector pair in the SS200 Digital Density Gauge. It is the detector-card component of the SS200’s Detector Unit, pairing with the DDG Receiver PCB (1230-90-2102) to drive the detector chain that relays density information to the control electronics. The detector chain comprises a stainless steel detector assembly (4060-90-0007-SS) and a scintillation detector (4060-00-0008-S), featuring a 2" x 2" NaI(Tl) crystal that converts radiation interactions into electrical signals for density calculations. The SS200 is a fully digital, nucleonic density gauge designed for continuous density measurements of slurries, sewerage sludge, and liquids in mining and mineral processing environments, with rugged IP67 construction and automatic gain stabilization to maintain accuracy. The system emphasizes low source activity and high repeatability, with test results cited in the manufacturer data sheets showing repeatability of 0.0001 SG when calibrated. The 1230-90-2000-D designation identifies this PCB as the DDG Transmitter, while the companion 1230-90-2102-DDG Receiver completes the detector pair in the official parts catalog for the SS200 digital density gauge.
