Thermal Dispersion Flow Switch delivers 0.07 fps repeatability.
Electrical Equipment & Systems

Thermal Dispersion Flow Switch delivers 0.07 fps repeatability.

Using impulse thermal dispersion measurement technique, Series TDFS indicates whether flow rate is above or below user-set value, from 0.5-10 fps, with NO and NC NPN outputs. Setpoint is field set by tapping included magnet on desired rate 3 times, and 2 LED status indicators on opposite sides of unit illuminate green and red when flow is above and below setpoint, respectively. Also, empty pipe...

Temperature Switches detect limits in gases or liquids.

Suited for OEM applications where detection of cold/high temperature limits is required, Series 11 senses temperatures from freezing to 90°C, in 16 narrow, differential preset trip points. Because they have no built-in differential, switches are creep mechanisms characterized by slow make/slow break and rapid cycling capability. Each consists of bi-metallic sensing mechanism packaged in...
