FAST AND PRECISE MEASUREMENT OF THE SURFACE TEMPERATURE Our surface temperature probes are used for surface temperature measurements on smooth surfaces in machine building industry. The sensors measure the surface temperature of workpieces or parts of the plant for the control of the entire process or the safety of the plants. The measurement and the feedback to the control system needs to be precise and fast. For this reason, surface temperature sensors need a design and material that allows them to be be thermally ideally coupled to the measuring point. Each measuring task requires a perfectly adapted geometry in order to increase the contact area and reduce the response time. Testo Sensor offers you a versatile portfolio of suitable temperature sensor types with qualified design. Technical requirements Surface temperature probes Surface temperature probes detect surface temperature. The most important issue in surface temperature measurement is to keep measurement errors as small as possible. This is achieved by an appropriate design of the measuring head, so that only very little heat is extracted from the measuring point and the measurement error is negligible. The perfectly adapted geometry increases the contact surface. At the same time, the low thermal mass of the measuring head ensures that comparatively fast response times can be achieved when measuring the surface temperature. The material of the measuring head has an important effect due to the different thermal conductivity. Stainless steel 316L and aluminum are available.
