4. About measured gas and contact failure
a) Corrosive gas
If the gas to be measured contains corrosive gases (nitric acid, hydrogen sulfide, sulfurous acid,
ammonia, chlorine, and so on), they may cause electrical contact failure or corrosion of internal
mechanism, which leads to malfunction of the switch. Do not use the switch for the gases containing
high humid air because in such gases, the arc generated by opening/ closing the contact produces nitric
acid, and it may also cause electrical contact failure or malfunction of switches.
b) Silicone gas
If the gas to be measured contains silicon produced from silicon (contained in oil, grease, filling agent,
and so on), the gas produced by arc, generates by opening/ closing the contact, accumulates on the
contact surface and causes contact failure. Take corrective measures such as the removal of the gas
source or arc suppression.
c) Dust and organic gas
The micro switch used in a Manostar switch is installed in the positive pressure measurement chamber.
The gas to be measured can easily flows into the chamber, thus, the composition of the gas largely
affects the formation of the film. In addition, the dust contained in the gas to be measured can adhere to
the contact surface and be changed into carbide caused the contact failure by the arc generated when
the contact is opened or closed. Therefore, pay attention to the measurement environment as well.
(Even with gold alloy contact, be careful about the dust.)
!
Caution
As the opening/ closing frequency of the contact increases, wear dust from the contact
increases. This wear dust accumulates between the contacts to increase the contact resistance
and causes the malfunction in the load circuit.
In particular, the surrounding where there exists continuous vibration and impact will be most
likely to cause contact failure due to worn powder.
