4-2 Situations to be avoided whenever possible
1) Water condensation
Light condensation under conditions of indoor usage
should not pose a problem for sensor performance.
However, if water condenses on the sensor’s surface
and remains for an extended period, sensor
characteristics may drift.

2) Usage in high density of gas
Sensor performance may be affected if exposed to a
high density of gas for a long period of time,
regardless of the powering condition.
Sensor performance may be affected if exposed to a
high density of gas for a long period of time,
regardless of the powering condition.
3) Storage for extended periods
When stored without powering for a long period, the
sensor may show a reversible drift in resistance
according to the environment in which it was stored.
The sensor should be stored in a sealed bag
containing clean air; do not use silica gel. Note that
as unpowered storage becomes longer, a longer preheating
period is required to stabilize the sensor before usage.

contamination levels for a long period of time, sensor
performance will be adversely affected.
5) Vibration
Excessive vibration may cause the sensor or lead
wires to resonate and break. Usage of compressed
air drivers/ultrasonic welders on assembly lines may
generate such vibration, so please check this matter.

6) Shock
Breakage of lead wires may occur if the sensor is
subjected to a strong shock.

7) Soldering
Ideally, sensors should be soldered manually.
However, wave soldering can be done under the
following conditions:
Ideally, sensors should be soldered manually.
However, wave soldering can be done under the
following conditions:
a) Suggested flux: rosin flux with minimal chlorine
b) Speed: 1-2 meters/min.
c) Preheating temperature: 100
b) Speed: 1-2 meters/min.
c) Preheating temperature: 100
±
20˚C
d) Solder temperature: 250
±
10˚C
e) Up to two passes through wave soldering machine allowed
Results of wave soldering cannot be guaranteed if con-
ducted outside the above guidelines since some flux
vapors may cause drift in sensor performance similar
to the effects of silicone vapors.
