What happens if I expose a sensor to pressures outside the quoted operating range?
The sensors all use a similar sealing system which relies on the hydrophobic properties of ptfe to prevent liquid passing out of the sensor even though there are holes to allow gas in. If the pressure at the sensor inlet is suddenly raised or lowered by more than the allowable limits the pressure across the internal membranes and seals may become large enough to cause leakage to occur. If the pressure change takes place slowly enough it is possible to use the sensors over wider limits but the advice of the technical support group at City Technology should be sought.
