The indicator, capillary, and thermobulb are a single unit filled with liquid or gas. These liquids or gases will respond properly in spite of any peripheral temperature changes. The compensator exists in order to automatically control any changes owing to temperature fluctuations in these liquids and gases, which are highly susceptible to temperature changes under normal circumstance.
For Single Capillary Types
Because the compensator is housed within the case, it is necessary to keep the capillary at the same temperature as the case. This type of compensator is called a "Case Compensator" or a "Bi-metallic Compensator." Our gauges having this type compensator have a model number that start with "1."
For Double Capillary Types
In each gauge the bourdon tubes and the capillaries are grouped into two sets. One set is for temperature measurement, while the other set is for temperature compensation. This Gauge will compensate reliably even under local temperature fluctuation.
This feature is called "Full Compensation" and places this Gauge a grade above gauges with so-called "Case Compensation." Our products having full compensation have a model number that start with "2."
