SE1620汽油發(fā)動機轉(zhuǎn)速表SE-1620 Tachometer
|
能對應各式各樣的點火脈沖傳感器，只要一接上就能測出汽油發(fā)動機的轉(zhuǎn)速。量程比前一個型號要寬一倍，達20,000r/min。模擬表頭采用2重刻度顯示。 輸入和輸出端以及電源輸入都采用隔離屏蔽裝置，所以能輸出高質(zhì)量、抗干擾性強、穩(wěn)定性好的模擬信號和脈沖信號。 |
特點
· 可測至 20,000 r/min
· 能對應各種各樣發(fā)動機的轉(zhuǎn)速傳感器，同時也能對應 5V 系列 ECU 的轉(zhuǎn)速脈沖輸入
· 通過對輸入靈敏度的選擇和調(diào)整，使輸入信號根據(jù)不同的點火系統(tǒng)和傳感器達到最佳程度
· 采用100mm見方的廣角表頭，視角寬廣，便于讀取數(shù)據(jù)
· 采用直流供電(12VDC或24VDC)，方便用戶進行車載或野外試驗
· 模擬輸出及脈沖輸出為標準配置

SE1620 SE-1620 Tachometer gasoline engine tachometer
Corresponding to every kind of ignition pulse sensor, aconnection can measure the speed of a gasoline engine.Wide range one times than previous models, up to 20000r/min. Simulation with 2 scale display meter.
The input and output and power input are isolated byshielding device, so the analog signal output high quality,strong interference resistance, good stability and pulse signal.
Characteristic
· can be measured to 20000 r/min
· can speed sensor corresponds to a variety of engine,but also the corresponding 5V series ECU speed pulse input
The selection and adjustment of the input sensitivity, so that the input signal according to the ignition system andsensors of different optimal degree
· wide-angle header, the 100mm square, wide visual angle, easy to read data
The DC power supply (12VDC or 24VDC), convenient for the user to test vehicle or field
· analog output pulse output is standard
