In the absence of customer specification, the switch point will be preset on falling
(1)
pressure to the mid point of the range [I.e. 50% of span + minimum range value]
The values indicate the maximum achievable limits of switch differential.
(2)
Set and reset point of the switch should not exceed the upper and lower range limits.
(3)
Maximum working pressure that the sensor element can withstand without suffering
(4)
any permanent damage. The instrument might have to be calibrated afterwards
