The model TF40 was developed specifically for use in ventilation ducts; the model TF41 for the measurement of outside temperatures.
The measuring elements of both sensors are inserted into a UV-resistant plastic housing that measures just 44(l) x 32(w) x 30(h) mm. The new instrument, classified with IP 65 ingress protection, can be supplied with a choice of Pt1000, Pt100, NTC or a customer-specific solution. Thus they are compatible with all the common control systems.
The model TF40 is tailored to the needs of air-conditioning and ventilation technology. Optional equipment includes a plastic mounting flange and a thermowell. The model TF41 is primarily suitable for the fields of renewable energies, HVAC and refrigeration technology. For this model, there is an additional, clip-on protective module to prevent erroneous measurements as a result of too strong incident sunlight in outside applications.
