Tachometer is widely used in industrial and transportation departments. It can monitor or control the operation of machinery by measuring the rotating machinery speed. The measuring principle of tachometer is as follows:\u003cbr\u003e1 convert the speed into angular displacement (such as centrifugal and magnetic tachometers); 2. Use the physiological phenomena retained by human vision (such as stroboscope); 3 convert the speed into voltage (such as speed measuring motor); 4 convert the speed into electric pulse frequency (pulse tachometer).\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cimg size=\"790x174\" align=\"absmiddle\" src=\"http:\/\/upload.ecvv.com\/upload\/allupload\/proimg\/detail\/67749662654\/0.jpg\"\u003e\u003cimg size=\"790x1244\" align=\"absmiddle\" src=\"http:\/\/upload.ecvv.com\/upload\/allupload\/proimg\/detail\/67749662654\/1.jpg\"\u003e\u003c\/p\u003e\n\u003cp style=\"display: none; color: #ffffff;\" data-mce-style=\"display: none; color: #ffffff;\"\u003e^_^:1f3649ad39e86be41eb72ce5326163f3\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"\" src=\"https:\/\/cdn.shopifycdn.net\/s\/files\/1\/0515\/0448\/0426\/files\/1_9928b955-fe1a-4f59-a289-24ed5dea0b0d_480x480.jpg?v=1627027215\"\u003e\u003c\/p\u003e\n\u003cbr\u003e","brand":"ECVV.UK","offers":[{"title":"Default Title","offer_id":41327133065386,"sku":"67749662654","price":63.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0598\/9521\/8346\/products\/1_7f20fb2e-0810-4c96-8fe1-0dfbb4fc26a1.jpg?v=1631244743","url":"https:\/\/ecvv.co.uk\/products\/tachometer-non-contact-digital-tachometer-photoelectric","provider":"ECVV.CO.UK","version":"1.0","type":"link"}
