Cable sensors with heat shrink tubing insulation

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.

Customized Kabelthermometer Made in Germany

Customized cable thermometers made in Germany by Delta-R from Mannheim. More and more sensor manufacturers are producing their cable sensors in subsidiaries in other European, Asian, or Arab countries. The resulting cost savings from lower wages, even before the pandemic and tariffs, came at the expense of delivery speed and flexibility. Significantly increased shipping costs and trade barriers have made domestic manufacturers more attractive. Customers have also shifted their thinking. Reliable supply chains are now considered essential. Local sourcing is trending. Procurement close to home is also preferred for environmental reasons. Increasingly, consumers are asking themselves, not just when it comes to clothing, whether products have to travel halfway around the world before they are finished. Delta-R has consciously chosen to continue manufacturing exclusively in Germany. Customer proximity fosters both speed and flexibility in the production of customized cable thermometers. Due to internationally limited supply chains and the resulting delivery times of sometimes several years, variability in sensor manufacturing has become essential. At Delta-R, this flexibility extends to allowing customers to supply their own raw materials upon request.

Founded in Mannheim in 2001, the companies portfolio includes consulting services related to sensor technology, manufacturer-independent trading of sensor components, and the custom assembly of cable sensors.

Coil-wound sensors for electric vehicles

Coil-wound sensors for electric vehicles Delta-R manufactures wound-head temperature sensors for electromobility on behalf of sensor manufacturers for the growing electromobility market. Speed, flexibility, and reliability, combined with the highest quality standards ;Made in Germany; have convinced an increasing number of customers during the pandemic. Wound-head sensors for electromobility are cable thermometers used for temperature monitoring of electric motors and batteries. These cable thermometers are temperature sensors with a cable extension and heat-shrink tubing insulation. These heat-shrink tubing temperature sensors are usually based on a Pt100 or Pt1000 element, which is extended in a 2-, 3-, or 4-wire configuration and then insulated with high-voltage-resistant heat-shrink tubing. Depending on the required temperature resistance, the sensors are insulated with high-voltage-resistant Kynar or PTFE heat-shrink tubing. 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. The operating temperature range of cable sensors with heat shrink tubing insulation is between -70°C and +260°C. Winding-head temperature sensors with a wide variety of connection technologies are available on the market. Delta-R prefers welding as a connection technology because it requires no filler material and is also suitable for small dimensions. However, brazing or crimping connections are also common and possible mechanical connection methods.
