Maestro Temperature Sensors

Temperature sensors measure the temperature of the environment in which they are installed, for both comfort and safety purposes. When connected to appropriate devices, they allow for active temperature control of a space or trigger corrective action in the event of anomalies. This is, for example, their typical application in electric motors, transformers, and electrical machinery in general, where they protect the device by cutting off the power supply in the event of excessive overheating.
When paired with a digital controller, these sensors are ideal not only for temperature control but also for programming corrective acyions when a critical value is reached.

Maestro RTD temperature sensors utilize a platinum chip of our own design, which allows for assembly using automated machinery. This enables faster and more precise assembly, as well as better repeatability of the finished product, consistent performance, and a higher-quality end result.

Overmolding with an engineering polymer provides exceptional mechanical strength. Like our bimetal thermal switches, our temperature sensors are also manufactured using an automated process and are 100% tested in-line.

PT100 and
PT1000


Our co-molded PT-RTDs (Platinum Resistance Temperature Detectors) are available in both PT100 and PT1000 versions, which differ in their reference resistance at 0°C (100 Ω and 1000 Ω, respectively).

    FAQ

    Its operation is based on the mechanical deformation of a strip composed of two metals with different coefficients of thermal expansion. When the calibration temperature is reached, the strip bends instantly, snapping and opening the electrical contacts to interrupt the circuit.

    The tripping times depend on the thermal curve of the application and the type of thermal insulation of the device. Maestro protectors are designed to ensure rapid tripping, especially in critical conditions such as progressive overload or a locked rotor in an electric motor.

    Yes. As direct manufacturers, we develop thermal protectors with tripping thresholds calibrated to the customer’s specific needs, covering standard and special temperature ranges for industrial OEM applications.

    The PTC thermistor is a semiconductor sensor that changes its electrical resistance but requires an external electronic circuit to interrupt the current. The Maestro bimetallic protector, on the other hand, is a self-contained electromechanical switch that physically and directly interrupts the flow of current, offering superior intrinsic safety without the need for additional control boards.
