Head Sensors

PWF 310

APPLICATIONS

Resistance sensors with connection heads are for solid, fluid or gaseous mediums. They are used for example at pipelines, within Heater and oven constructions. The interchangeable gauge slide is a standard Pt100 class B with two-wire circuit. Three- and four wire circuits resistance sensors class A as per IEC 751 are as well available. The B-shaped connection head is for surrounding temperatures up to 100 °C. BBK-heads goes up to 120 °C. The PWF 310 are manufactured with protection tube diameters of 9 mm and 11 mm. The fitting length is free selectable from 160 mm.  A G ½” screw-in pivot is welded on the protection tube for fastening

Resistance Sensor plug connectors

The standard plug connectors are due to their construction reverse-polarity protected and up to 120 °C temperature stable. The round U type contact pins are out of copper (plus pin Ø 4 mm - minus pin Ø 4.7 mm). The plug is white and suitable for cross sections up to 1 mm². We recommend to assemble a strain relief with the plug and socket. This avoids the relieve of the leads from the plug. A brass ferrule will be provided, please state lead diameter.
