This 20 bar absolute pressure sensor is specially designed for measuring the
pressure of liquefied gasses (like l.g.p.). Using an Absolute type pressure sensor
has a distinct safety advantage over a Gauge type pressure sensor for this type
of applications.
In case of a malfunction of the membrane of a Gauge type pressure sensor a gas leak could occur.
Using an Absolute type pressure sensor completely circumvents this safety issue.
The trade-off is that the connecting wires carrying the electrical signals have to be run inside the
pressurized container.
The TO5 metal can encapsulation is especially suited for mounting in a ruggedized brass fitting.
