Temperature Sensors
Temperature sensors measure process and ambient temperatures via resistive probes (Pt elements) or integrated transmitters with analog and switching outputs. Typical use covers hydraulics, machine cooling circuits, process tanks, and OEM equipment monitoring. Output options include current signal plus pnp/npn transistor switching for direct PLC integration.
The assortment splits into bare probe variants (Fühler) and transmitters with current output and switching stage. Probe diameters cluster at 6 mm, 4.4 mm, and 3 mm, covering insertion into small bores up to standard thermowells. Compact transmitter families include the H1140 and L250 series.
Supply voltage ranges follow standard industrial DC rails: 18 …32 VDC, 12 …32 VDC, 10 …32 VDC, and 8 …32 VDC. Conductor cross-section options are 0.5 mm² and 4 mm² for connection cabling.
Ambient ratings cover -40 …+80 °C for outdoor and unheated installations, and -20 …+80 °C for typical machine environments. Manufacturer focus is on Turck and IPF.
Price points span entry-level probes around 139.70 EUR up to configured transmitters at 1208.40 EUR, with mid-range variants at 263.90 EUR and 433.40 EUR. Special versions include combined current output with pnp/npn switching stage (LI6 interface) for direct integration into machine controls.
