Strain Gage Multiplexer Overview
The strain gage multiplexers, together with the HP E1326B/E1411B
Multimeter, provide static and dynamic strain measurement capabilities for
an HP Series B or Series C VXIbus system.
Physical
Description
The HP E1355A and E1356A are B-size, 8-channel, 120Ω and 350Ω
RELAY Strain Gage Multiplexers, respectively. The HP E1355A and
E1356A terminal modules use the HP E1345-66201 component assembly.
The relay multiplexers use a single B-size or C-size mainframe slot.
The HP E1357A and E1358A are B-Size, 8-channel, 120Ω and 350Ω FET
Strain Gage Multiplexers, respectively. The E1357A and E1358A terminal
modules use the HP E1351-66201 component assembly. The FET
multiplexers also use a single B-size or C-size mainframe slot.
