Sensor Location:
Several factors should be considered when selecting locations to install
sensors. The following general suggestions should be considered to assure
the detection of the target gas. Select the most suitable location for each
sensor.
1. Air Currents: If there are fans, winds, or others sources of air movement,
B
Terminator Enable/Disable?
The terminator on each end of the RS485 loop is designed to
match the electrical impedance characteristic of the twisted pair
loop, and will prevent signal echoes from corrupting the data on
the line. The terminator should be enabled on BOTH ends of the
RS485 loop. Short and medium length modbus/485 loops can
operate without the terminating resistor. Longer runs may require
the terminating resistors. But adding terminator dramatically
increases power consumption.
Twisted Pair?
RS-485 is designed to be a balanced system. The signal on one
A
wire is ideally the exact opposite of the signal on the second
wire. In other words, if one wire is transmitting a high, the other
wire will be transmitting a low, and vice versa. Although RS-485
can be successfully transmitted using multiple types of media, it
should be used with wiring commonly called "twisted pair."

gases may tend to rise to collect in certain areas of a facility. The local air
currents should be assessed to aid in selecting the sensor location. In outdoor
situations considerations such as prevailing winds should be accounted for.
Air convection can often be more important in determining gas concentrated
areas than factors of Vapor Density.
2. Vapor Density: R11, R22, R123 and R134a are heavier than air. Detecting
location should be 9 - 18 inch (0.23m to 0.46m) above the floor.
3. Gas Emission Sources: As a rule, at least one sensor should be located in
close proximity to each point where a leak is likely to occur. This is particularly
important when a liquid having a low volatility is monitored.
4. Environmental Factors: Designed to rugged outdoor use consider the
following in selecting locations. Install sensors where they will be protected
from wind, dust, snow, water, vibration and shock.
