The Metrolog SD20p conditioner is a high performance signal conditioner for industrial, laboratory and research applications
Its primary function allows direct conversion of pneumatic measurement gages (air plugs, air rings, snap gages, among others) to 1Vpp/TTL incremental signal or to RS232/USB communication interface.
Features
Full digital air conditioner, without analog or pneumatic adjustment requirements.
High stability and typical working resolution of 0.1µm..
Internal and external calibration capabilities.
State-of-the-art signal conditioner featuring a 24-bit high precision A/D converter and adjustable digital filters.
Open communication protocol, allowing user application development and connectivity with many commercial software.
Compatible with programmable logic controllers (PLC) with available input for incremental quadrature signals (1Vpp or TTL standard), typically used with linear and rotary encoders.
Compatible with Heidenhain readouts (Gage-Chek, Quadra-Chek, ND287, among others) with available input for incremental quadrature signals (1Vpp or TTL standard)
Compatible with Metrolog M20-4E measurement column.
Compatible with microcomputers and other equipment with RS232 or USB ports.
