Meggitt GSI130 / 244-130-000-20- obsolete replaced by GSI 127 / PNR 244-127-000-017-A1-B01/B02
Galvanic separation unit for use with vibration sensor (CA, CE, PV and VE), dynamic pressure sensor (CP) or proximity sensor (TQ) measurement chains.
The GSI127 galvanic separation unit is a high-quality, high-reliability unit for use with the IPC704 signal conditioner (used by CA accelerometers and CP dynamic pressure sensors), current-output accelerometers such as the CE134, CE281 and CE311, constant-current voltage-output sensors such as the CE110I, PV102 and CE680Mx11, the IQS450 signal conditioner (used by TQ proximity sensors) or the VE210 velocity sensor.
The GSI127 has a configurable transfer function and provides a voltage output. It is designed and built for long-term use in environments characterised by hazardous areas (potentially explosive atmospheres).
