FS SERIES CIRCUIT
1.
Circled numbers refer to sensor
terminals (pins).
Pin 1 = Supply V
S
(+)
Pin 2 = Output (+)
Pin 3 = Ground (-)
Pin 4 = Output (-)
2.The force sensor may be powered
by voltage or current. Maximum
supply voltage is not to exceed 12
volts. Maximum supply current is
not to exceed 1.6 mA. Power is
applied across Pin 1 and Pin 3.
3.The sensor output should be
measured as a differential voltage
across Pin 2 and Pin 4 (V
O
= V
2
-
V
4
). The output is ratiometric to the
supply voltage. Shifts in supply
voltage will cause shifts in output.
Neither Pin 2 nor Pin 4 should be
tied to ground or voltage supply.
* Non-compensated force sensors, excited by constant current (1.5 mA)
instead of voltage, exhibit partial temperature compensation of Span.
**BFSL: Best Fit Straight Line.

CLEANING
Proper cleaning fluids should be
selected, based on the type of
contaminants to be removed.
Honeywell recommends alcohols.
