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

A declaration of conformity is not documented in the datasheet. Before sizing, note: The setting range is a flow velocity; the flow rate depends on the pipe bore. Data block and order code disagree on the supply; only 24 V DC can be ordered, and a 230 V AC version has to be confirmed first. The pressure of the installed assembly is set by the accessory; the conventional stainless tee is rated 40 bar.\u003c\/p\u003e\u003ch3\u003eAdvantages at a glance\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eHousing and probe entirely in stainless steel\u003c\/li\u003e\u003cli\u003eCalorimetric principle with no moving parts\u003c\/li\u003e\u003cli\u003eSettable for water, oil and air\u003c\/li\u003e\u003cli\u003eOutput PNP, NPN or SPDT relay\u003c\/li\u003e\u003cli\u003ePressure rating 100 bar at the switch\u003c\/li\u003e\u003cli\u003eProtection IP67\u003c\/li\u003e\u003cli\u003eLED row with six LEDs for switching state and velocity trend\u003c\/li\u003e\u003c\/ul\u003e","brand":"octogon GmbH","offers":[{"title":"Default Title","offer_id":57453412909382,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/5558\/6374\/files\/QSKC_produkt.webp?v=1790331873","url":"https:\/\/octogon-sensors.com\/en\/products\/qskc-calorimetric-flow-switch-stainless-steel","provider":"octogon GmbH","version":"1.0","type":"link"}
