Supplied Accessories:
2) Mounting Stud Model 620
Notes:
[1] Glass to metal Seal connector. Mates with Dytran cable model 6811AXX or 6824AX
[2] Measured at 100 Hz, 1 Grms per ISA RP 37.2
[3] Linearity is % of specified full scale (or any less full-scale range), zero-base
best fit straight line method.
[4] Do not apply power to this device without current limiting, 20mA Max, to do so wil
destroy the integral IC amplifie
