WH9A/WH9V Linearizer
Brand: Yokogawa Electric Corporation
The WH9A/WH9V is a compact, front terminal connection type isolator that receives non-linear signals generated by analyzers or sound level meters, and converts them into linear DC current or DC voltage signals.
Features- Zero/span adjustment, input/output monitoring, can be made using the optional parameter setting tool (VJ77) or handy terminal (JHT200)
- Dual output and 2,000 Vac withstand voltage specifications are available
