Detailed Product Description
SGD20 is equivalent to Meas\ Macro sensors' for general purpose.
The DC-operated LVDT sensor performs excellently with a maximum measuring range of 50mm, maximum resilience of 200 gram. It operates from a single-ended 9-28 DC power supply, output standard signal of 0-5 DC or 4-20 mA to be identified by computer or PLC. The senor probe shaft is constructed entirely of anti-friction chromium tool steel, and electrical circuit is rugged hermetically sealed in SUS 304 stainless steel sleeve to resist hostile environment of damp and dust, etc.
