It is particularly suited to water, cutting fluid, lubricating oil and air in pneumatic and hydraulic systems, and to pump dry-running protection.\u003c\/p\u003e\u003cp\u003eA heated and an unheated resistor in the probe sense the flow velocity.

The datasheet states \u003cstrong\u003eEx d IIC T6\u003c\/strong\u003e; a certificate is not documented. A declaration of conformity is not documented in the datasheet. Before sizing, note: The explosion protection is optional in the order code, and a certificate and a separate ambient range for explosion-proof service are missing. Data block and order code disagree on the supply; only 24 V DC can be ordered. The setting range is a flow velocity; the flow rate depends on the pipe bore.\u003c\/p\u003e\u003ch3\u003eAdvantages at a glance\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eCalorimetric principle with no moving parts\u003c\/li\u003e\u003cli\u003eHousing in painted cast aluminium\u003c\/li\u003e\u003cli\u003eOutput PNP, NPN or SPDT relay\u003c\/li\u003e\u003cli\u003eM20 × 1.5 cable entry with terminal strip\u003c\/li\u003e\u003cli\u003ePressure rating 100 bar at the switch\u003c\/li\u003e\u003cli\u003eProtection IP67\u003c\/li\u003e\u003cli\u003eEight LEDs behind a window\u003c\/li\u003e\u003c\/ul\u003e","brand":"octogon GmbH","offers":[{"title":"Default Title","offer_id":57453578617158,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5558\/6374\/files\/QSKF_produkt.webp?v=1790331873","url":"https:\/\/octogon-sensors.com\/en\/products\/qskf-calorimetric-flow-switch-cast-aluminium-housing","provider":"octogon GmbH","version":"1.0","type":"link"}
