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.
