Delta-R expands its portfolio of cable sensors with heat-shrink tubing insulation. With this new range of coiled-head sensors, the temperature sensor specialist Delta-R has expanded its in-house manufacturing portfolio from purely customer-specific temperature sensors to include standard sensors. Cable sensors with heat-shrink tubing insulation, so-called coiled-head sensors, are used in thermal motor protection applications. These temperature sensors with heat-shrink tubing insulation are typically based on a Pt100 or Pt1000 element, which is extended in 2-, 3-, or 4-wire configurations and then insulated with high-voltage heat-shrink tubing. Depending on the required temperature resistance, the sensors are insulated with high-voltage heat-shrink tubing made of Kynar or PTFE. Depending on the voltage rating, the sensors are insulated with single or multiple layers. The required insulation strength determines the insulation length as well as the type and position of the heat-shrink tubing. Typically, the elements are extended with single-core stranded wire in the AWG 20 to AWG 28 range. UL-certified stranded wire is available from stock at Delta-R for many dimensions. The operating temperature range of cable sensors with heat-shrink tubing insulation is between -70°C and +260°C. Various connection techniques are possible. Delta-R prefers micro-welding as a connection method, as it requires no filler material. However, brazing or crimp connections are also possible as mechanical connection methods.
