SPD300ABTO05 Pressure Sensor
A 20 BAR ABSOLUTE PRESSURE SENSOR
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.
