The Thermatel® Model TD1/TD2 switch is utilized in flow, level and interface applications. The TD1/TD2 is popular for pump protection, specifically low flow detection with the unique spherical tip design, to prevent pumps from running dry.
Thermatel® TG1/TG2 provides a two-wire, intrinsically safe circuit between the probe and remote din rail enclosure. The flow/level/interface switches provide a new level of performance and reliability not found in previous switches.
