THERMATEL® TD2 Thermal dispersion switch FOR HYGIENIC USE Thermatel® TD2 switches can easily be adjusted to detect flow (gases and liquids), level or liquid-liquid interface. The TD2 is either V DC or V AC line powered and offers additionally LED indication, time delay and mA output for diagnostics and trending. The units have both 3A and EHEDG approval for use in hygienic applications. DESCRIPTION For FLOW/LEVEL/INTERFACE applications F E AT U R E S • Easy field calibration • • • • • • • • – pre-calibration from factory at request. Variable flow or Flow/No flow detection of gases and liquids. Excellent low flow sensitivity. Automatic temperature compensation for repeatable alarm under varying process temperatures. Continuous diagnostics detect sensor fault. Continuous monitoring of flow rate versus setpoint via LED. mA output provides repeatable indication of flow rate and fault detection. Flow can be measured over test points. Suited for SIL1 loops (full FMEDA report available).

Worldwide level and flow solutions The unit utilises Magnetrolʼs proven thermal dispersion technology. The sensor consists of two RTD (Resistance Temperature Detector) 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. TECHNOLOGY 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. mA output - for trending: the calibrated setpoint corresponds with a specific mA value but although not linear, it provides important process information. With increasing flow or immerged sensor, the mA signal increases. - for diagnostics: either 3,6 mA (Low Level Fail-safe) or 22 mA (High Level Fail-safe) output, indicates for an instrument failure (sensor). A D VA N C E D F E A T U R E S Relay Test points Allow the user to periodically check the setpoint and verify for set point drift. The setpoints read voltage units. LED indication The LEDʼs show progressively actual flow/level versus the calibrated setpoint. Factory calibration TD2 can be delivered pre-calibrated at a fixed setpoint. TD2 can be delivered with a complete calibration curve, allowing the customer to field adjust the setpoint by using a voltmeter at the test points. 2 mA Testpoints L1 L2 NC C NO NC C NO TP2 TP1 TIME DELAY ALARM Calibration MODEL TD2 Damping LED indication FLOW Thermatel® TD2 switches may be installed in a variety of flow applications as shown in the illustration below. Flow/No Flow can be detected in an input line to a primary tank, or in an output line. They may be installed for overflow detection in a pipe connected to an overflow tank or installed in a drain line for Wet/Dry indication. In addition, due to the capability to detect liquids or gases, the Thermatel® flow switch may be installed in a gas vent to detect off-gas from the primary tank.

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. Centrifugal pump protection 3 A complete measuring system consists of: S E L E C T I O N D ATA 1.
