MAGNETROL TD2-7D00-074

Hygienic Thermatel®
Thermal Dispersion
Flow & Level Switch
D E S C R I P T I O N
Designed for use specifically in the clean or hygienic
process industry, the Thermatel TD2 is an outstanding
flow/level switch where easy external wipe-down and a
sensor free of cracks and crevices are required. The TD2
Thermal Dispersion Flow/Level switch provides
continuous diagnostics, temperature compensation
narrow hysteresis, and fast response time for superior
performance.
The TD2 switch uses either AC or DC input power, provides a DPDT relay output with a visual LED indication
of status through the glass window in the cover. Other
features include ability to electronically measure the set
point, a mA output signal for trending and diagnostics
and time delay.
See Magnetrol Brochure 54-110 for additional information and complete specifications.

• Temperature compensated to provide repeatable
alarm under varying process temperatures
• Continuous diagnostics detect sensor fault
• A non-linear mA output signal can be used for
trending, diagnostics and repeatable flow/level
indication
• Detects minimum flow or presence/absence of flow
• Simple/fast calibration
• Excellent low flow sensitivity
• Process temperatures from -100° to +400° F
(-73° to +204° C)
• Fast response time
• 316 stainless steel probe with 32 Ra finish
The Thermatel TD2 switch utilizes Magnetrol proven
thermal dispersion technology. The 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.
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.

PUMP PROTECTION
Discharge Flow ¬
Installed on the suction or discharge of a pump, a
Thermatel switch provides rapid indication of a low flow or
no flow condition to prevent pump damage. No moving
parts, excellent low flow sensitivity, and low hysteresis
between alarm and reset points are all important features in
this application. Enhanced temperature compensation minimizes set point drift due to varying process temperatures.
