The flow\/level\/interface switches provide a new level of performance and reliability not found in previous switches. Continuous diagnostics with fault indication, narrow hysteresis and fast response time make the TG1\/TG2 the latest in thermal dispersion switch technology.<\/p>\n<p><strong>Operating Principle <\/strong><\/p>\n<p>The THERMATEL sensor consists of two RTD elements. One is the reference and the second is heated to a temperature above the process temperature. The electronics detect the temperature difference between the two elements. The temperature difference is greatest in air, then decreases when cooling occurs due to a change in media. An increase in the flow rate further decreases the temperature difference.<\/p>\n<p>The set point is adjusted for the switch to alarm at the desired temperature difference. Once the set point is reached, the relay will change state.
