The Engine Tachometer is supplied as 12V DC with 230V and 115V AC power available. The gauge reports output in 4-20mA, 0-5V, and TTL formats. There are two alarm set points that are user selectable. The accuracy is within 2 RPM per 1,000 and measures from 200 to 10,000 RPMs on 8 cylinder engines.\u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003eThe OM-200 electromagnetic indicative sensor will detect the high voltage flux induced from the ignition coils, magnetos, or transistorized ignition system. The OM-200 sensor is mounted parallel to the ignition power distributor. The alternative method uses an optical sensor (ROS-5) to reflect off a mark on the sleeve producing accurate RPM readings. An NIST traceable certificate of calibration supplied with each instrument.\u003c\/div\u003e","brand":"Monarch Instrument","offers":[{"title":"Default Title","offer_id":48343364567252,"sku":"MON-6140-Engine","price":957.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0837\/0451\/2724\/files\/MON-6140-Engine-2.jpg?v=1785145793","url":"https:\/\/sejqw6-v1.myshopify.com\/products\/monarch-instrument-gasoline-engine-rpm-gauge","provider":"Reliability Direct Store, LLC","version":"1.0","type":"link"}
