Temperature gauges are reliable mechanical temperature measurement instruments used for accurate monitoring of process temperatures in industrial and hygienic applications. The remote bulb (capillary type) temperature gauge is designed to measure temperature at locations where direct mounting of the dial is not possible.

This type of temperature gauge consists of a stainless steel sensing bulb, a flexible armored capillary, and a dial indicator. Temperature changes at the bulb are transmitted through the capillary to the dial, providing precise and stable temperature indication without the need for electrical power.

Remote bulb temperature gauges are widely used in food, dairy, beverage, pharmaceutical, chemical, HVAC, and industrial process systems, especially where vibration, high temperature, or limited installation space is present.
