Mass balancing element Mass Flow THERMATEL switches rely on two miniature sensing elements to detect heat transfer. Resistance Temperature Detectors (RTDs) establish a thermal relationship that establishes the basis for flow and level detection. One RTD measures the temperature of the surrounding media which serves as the instrument’s reference temperature. The second RTD is heated to establish a temperature differential above the reference temperature. In flow sensing applications, the heated RTD cools with increasing flow. In level sensing applications, the RTD cools in the presence of...

Two-Wire Intrinsically Safe Flow / Level / Interface Detection General Description: The MAGNETROL TG1/TG2 switch is the industry’s only two-wire, intrinsically-safe thermal dispersion switch. The switch consists of a probe and preamplifier with remote DIN rail electronics. Barriers in the DIN rail enclosure provide a two-wire, intrinsically-safe circuit to the probe/preamplifier. Product Operation: The preamplifier converts the temperature difference to a pulse signal which is super-imposed on the two wires providing power to the sensor. The DIN rail electronics provide operation control...
