The alarm set point is adjustable from 0 to 100% of the air flow range. The unit comes with one green power LED, and one red LED for alarm indication. The FMA900A Series are used in research and development labs, HVAC applications, exhaust\/ ventilation hoods and other manufacturing processes. The sensor probe comes in two configurations, fixed mount 305 mm (12\") probe and remote 305 mm (12\") probe with 4.5 m (15') of shielded cable.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eSPECIFICATIONS\u003cbr\u003e Air Velocity Range:\u003c\/b\u003e 0 to 500, 0 to 1000, 0 to 2000, 0 to 5000, 0 to 10,000\u003cbr\u003e \u003cb\u003eAccuracy:\u003c\/b\u003e 2% of FS\u003cbr\u003e \u003cb\u003eAir Velocity Probe:\u003c\/b\u003e 6 OD x 305 mm L (¼ OD x 12\") stainless steel, or remote probe\u003cbr\u003e \u003cb\u003eHigh Alarm Set Point:\u003c\/b\u003e Adjustable from 0 to 100% of air flow range\u003cbr\u003e \u003cb\u003eAlarm Indication:\u003c\/b\u003e Red LED on the back plate\u003cbr\u003e \u003cb\u003eAlarm Deadband:\u003c\/b\u003e 5% of FS\u003cbr\u003e \u003cb\u003eRelay:\u003c\/b\u003e One 12V SPST NO relay\u003cbr\u003e \u003cb\u003eContact Rating:\u003c\/b\u003e 10A @ 24 Vdc\u003cbr\u003e \u003cb\u003eAnalog Output:\u003c\/b\u003e 0 to 5 Vdc, 4 to 20 mA\u003cbr\u003e \u003cb\u003eOperating Ambient Temperature:\u003c\/b\u003e\u003cbr\u003e     \u003cb\u003eSensor Probe:\u003c\/b\u003e -40 to 93°C (-40 to 199°F)\u003cbr\u003e     \u003cb\u003eElectronic Case:\u003c\/b\u003e 0 to 50°C (32 to 122°F)\u003cbr\u003e \u003cb\u003ePower Indicator:\u003c\/b\u003e Green LED\u003cbr\u003e \u003cb\u003ePower:\u003c\/b\u003e 15 to 24 Vdc @ 200 mA\u003cbr\u003e \u003cb\u003eDimensions:\u003c\/b\u003e 89 H x 51 W x 32 mm D (3.5 x 2 x 1.25\")\u003cbr\u003e \u003cb\u003eWeight:\u003c\/b\u003e 160 g (5.6 oz) \u003c\/span\u003e\n\u003c\/div\u003e","brand":"hkcalibrations","offers":[{"title":"No","offer_id":49818260635943,"sku":"FMA900A-Series","price":1590.58,"currency_code":"AUD","in_stock":true},{"title":"Yes (office will call you to confirm the cost)","offer_id":49818260668711,"sku":"FMA900A-Series","price":1590.58,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0907\/4124\/4199\/files\/fma900a_l_wstuboxvra8ly0am.jpg?v=1741338428","url":"https:\/\/hkcalibrations.com.au\/products\/hot-wire-air-velocity-transmitter-with-alarm-contact","provider":"hkcalibrations","version":"1.0","type":"link"}
