Thermatel® Model TD1/TD2
Thermal Dispersion
Flow/Level/Interface Switch
D E S C R I P T I O N
TD1 and TD2 Thermal Dispersion flow/level/interface
switches provide a new level of performance and
reliability not found in previous switches. Continuous
diagnostics with fault indication, temperature compensation, narrow hysteresis and fast response time make
the TD1/TD2 the latest in thermal dispersion switch
technology.
Model TD2
with spherical probe
TD1 is a basic switch with 24 VDC power and an 8-amp
DPDT relay. The TD2 adds LED indication through a
glass window, ability to electrically measure the set
point, mA output for diagnostics and trending, optional
hermetically sealed relay, plus time delay. A universal
AC power supply simplifies installation.
Thermatel® probes are available in 316 Stainless Steel,
Hastelloy® C, or Monel® with all welded construction.

• Temperature compensated to provide repeatable
alarm under varying process temperatures
The Thermatel® TD1 and TD2 switches utilize the
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.
• Continuous diagnostics detect sensor fault
• Non-linear mA output signal can be used for trending, diagnostics and repeatable flow/level indication
(TD2)
• Detects minimum flow or presence/absence of flow
• Easy/fast calibration
• Excellent low flow sensitivity
• Optional hot tap available (see bulletin 41-103)
• Hygienic design available
• NACE construction available (consult factory)
• Process temperatures from -100° to +400° F (-73° to
+204° C)—High temp. version to +850° F (+454° C)
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.

The THERMATEL flow switch can be ordered factory
calibrated to alarm at a specified flow rate. A complete
calibration curve can also be provided for the TD2.
Using this curve the user can determine the desired set
point. Using a volt meter, adjust the set point until the
desired alarm point is obtained. Calibration can be performed on water and select organic compounds.

One of the major concerns is questioning if the switch
will operate when an alarm condition occurs. The
TD1/TD2 is equipped with advanced diagnostics which
continuously monitor the signal from the sensor and
indicate if the signal has gone out of range. In the event
of a fault, the alarm relay will de-energize and the red
LED will blink. In the TD2 the mA output will change
to 3.6 mA (Low Level Fail-safe) or 22 mA (High Level
Fail-safe) to indicate a fault.
A D V A N C E D

mA output
The TD2 has a mA output signal can be used for diagnostics, fault detection and trending. While this mA signal
is not scalable by the user, it can provide important
process information. The mA signal will increase with
the sensor cooling – mA will be greater in a wet condition than in a dry condition and will further increase as
the flow rate increases.

Remote Electronics
The TD2 can be provided with remote electronics
with up to 500 feet (150 meters) separation between
the probe and electronics.
Hermetically sealed relay
The TD2 provides an optional hermetically sealed relay
for the most demanding applications.
The mA output can also be used for fault detection. In
the event of a fault, the mA output will follow NAMUR
NE 43 and go to less than 3.6 mA for Low Level Fail-safe
and greater than 22 mA for High Level Fail-safe selection.
Due to ATEX requirements the mA output is not
available on units for Zone 0 service (Model number
digit 9 = C).

Measure the set point
With the TD2 the user can obtain an electrical measurement of the set point. This permits the user to periodically check the calibration point and verify that the set
point has not changed. Due to ATEX requirements, this
feature is not available on units for Zone 0 service
(Model number digit 9 = C).

A P P L I C A T I O N S
THERMATEL has demonstrated reliable performance as a flow or level switch. For use as a flow switch,
THERMATEL can be used to detect either a high flow or a low flow condition for both gases and liquids.
As a level switch, THERMATEL can be used to detect difference in thermal conductivity of various media.
This includes interface detection between media such as liquid/foam, and oil/water.
L E V E L
S W I T C H
Level or Interface can be detected due to differences in
thermal conductivity. High or low level alarm applications may be installed either vertically or horizontally.
Low Level
In the absence of media, the self-heated sensor tip creates a temperature difference between the two sensors.
F L O W
S W I T C H
Flow is detected by an increase in heat transfer that
occurs as the flow rate increases. Exceptional low flow
sensitivity is obtained with no moving parts. The same
unit can be used for both liquid and gas flow detection.
No Flow
In a low flow condition, the self-heated sensor tip creates a temperature differential between the two sensors.
Flow
High Level
As media contacts the sensor tip, heat is absorbed by the
fluid, decreasing the temperature difference.
4
As flow increases, heat is dissipated and temperature
difference decreases.
PROBE
DESIGNS
THERMATEL offers two sensor tip designs—the original
twin tip and the unique spherical tip. Both designs
have similar operating ranges.
The sensors in the twin tip are mounted at the end of
each tip. In the spherical tip, the sensors are bonded
directly to the wall of the tip, providing protection of
the sensors.
The spherical tip is recommended for all types of
applications—general purpose, high viscosity, and
applications where buildup can occur.
Twin tip
buildup, and hygienic service. Suitable for gas
flow applications. Maximum temperature of
+400° F (+200° C).
Twin Tip
For higher pressures up to 3000 psig, corrosion resistant
materials including Monel and Hastelloy C. Twin tip
probes are preferred for air flow applications.
Maximum temperature of +400° F (+200° C).
High Temperature/High Pressure (HTHP)
Suitable for temperatures up to +850º F (+454º C)
Pressures up to 6000 psi (410 bar). Available in both
316/316L stainless steel and Hastelloy C construction.
Spherical tip
Mini Sensor
This twin tip sensor is suitable for installing in a Tee
in smaller pipe sizes. Available with 1⁄2", 3⁄4" and 1" NPT

PUMP PROTECTION
Installed on the 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.
Pump Protection
COOLING WATER/COOLING AIR
Maintaining the flow of cooling air or water is essential to
protect heat generating equipment. A reliable flow switch
will ensure that sufficient cooling media is flowing in the
pipe. A low flow alarm will provide indication of inadequate
cooling prior to overheating of the device being protected.
Cooling Water/Cooling Air
LEVEL

level
alarm
A THERMATEL switch can be calibrated to detect the difference between two media based upon the difference in
thermal conductivity. This can include wet/dry, oil/water
interface, air/foam and foam/liquid. The sensitivity of the
switch can easily be adjusted for a wide range of conditions.
Probes can be mounted from the top or side of the tank.

CHEMICAL FEED PUMPS
Monitoring the addition of chemicals into a process is vital
for good performance. The TD1/TD2 with the low flow
body can handle extremely low flow rates of both liquids
and gases. With the TD2, time delay can be added.

RELIEF VALVE MONITORING
When installed downstream of a relief valve, the switch can
detect when flow occurs. The low flow sensitivity of the
sensor permits the switches to be calibrated to detect minor
valve leakage.
LUBRICATION SYSTEMS
Relief Valve Monitoring
The flow switch with the low flow body can be used to
ensure that sufficient quantities of lubrication oil are flowing throughout the entire lubrication system. No moving
parts and large openings prevent buildup or plugging
which can occur with mechanical switches.
