In various industrial fields, there is a demand for remote reading of pressure gauges or distant installation of pressure instruments and that is when InstruMate capillary tube finds one of its core applications.

Other main advantage of capillary tube model 8118 is protecting the instrument from high and low process temperatures.

InstruMate 8118 benefits from stainless steel armor for better protection.

Note that the capillary length must be chosen as short as possible to maintain acceptable response time. Longer capillary lengths might affect accuracy as they are more vulnerable to ambient temperature changes.

If the capillary tube is used in combination with a diaphragm seal, make sure there is no level difference between the pressure instrument and the diaphragm seal as it can cause indication error.
