4.2 CABLE SELECTION AND WIRING

Connection should be made using 3-conductor, shielded cable (shield must be grounded at the
power supply). See Figure 4 to select cable length and wire gauge according to supply voltage.
Run cable through steel conduit for best signal transmission and maximum noise rejection.
4.2.1 TRANSMITTER INTERFACE TO COMPUTER, DATALOGGER OR NON-AMC
SYSTEM
All Armstrong transmitter/sensor units can be interfaced with computer terminals or dataloggers
through Analog-to-Digital converters. The transmitter output (-, s, +) terminal block connects to a
filtered, DC power supply through field wiring. (see Figure 3)
The signal output from the transmitter is a 4 to 20 milliamp DC current. This can be measured
from the signal wire, or if a voltage measurement is needed, connect a resistor (250 ohms max.)
between the transmitter signal output (s) and power supply ground (-).
