What is the Ceraphant PTP31B?
Absolute vs Gauge Pressure — how PTP31B handles them
To understand how this switch supports both, it helps to recap what “absolute” and “gauge” pressure mean, then see how the PTP31B implements them:
Because atmospheric pressure is nonzero, in many processes you need an “absolute” reading, especially when working under vacuum or when atmospheric fluctuations matter.
The PTP31B supports both modes (depending on configuration and sensor variant) by using internal reference conditions or sensor types that allow measurement referenced to absolute zero.
In its documentation, the device is described as being for “absolute and gauge pressure” measurement.
