The TR 158 temperature sensor is designed for measuring the surface temperature of ferromagnetic bodies with a temperature range of -30 to 150 °C. The minimum surface diameter for sensor placement must be 28 mm, allowing its use in a wide range of applications. Thanks to the sensor's design, a quick response to temperature changes is ensured, especially when using silicone grease or thermally conductive paste for better thermal contact. The sensors are intended for use in chemically non-aggressive environments, and their use must be adapted to the temperature and chemical resistance of the casing and supply cable.
