SE 1620

Product catalog summary

Overview: The SE-1620 is a gasoline engine tachometer designed to measure engine revolutions by connecting to an engine revolution sensor, such as an ignition pulse detector. It features a 100-mm wide-angle meter for display and provides both analog and pulse output functions.

Specifications:

Measurement Ranges: For 2-cycle engines: 1-2 cylinders (500-20,000 r/min), 3 cylinders (500-16,000 r/min), 4 cylinders (500-12,000 r/min). For 4-cycle engines: 1-5 cylinders (500-20,000 r/min), 6 cylinders (500-16,000 r/min), 8 cylinders (500-12,000 r/min), 10 cylinders (500-10,000 r/min), 12 cylinders (500-8,000 r/min).
Display: 100-mm wide-angle meter, Class 1.5, with a double scale of 0 to 10,000 r/min or 0 to 20,000 r/min.
Power Supply: 12 V to 24 VDC, with a current consumption of approximately 470 mA at 12 VDC.
Operating Conditions: Temperature range of 0 to 40°C, storage temperature range of -10 to 60°C, and humidity range of 80% RH max (non-condensing).
Dimensions and Weight: 221 (W) x 116 (H) x 150 (D) mm, approximately 1.3 kg.

Output Section:

Analog Output: Voltage range of 0 to 10 V, with a setting accuracy of ±0.2%/FS for zero and ±0.3%/FS for span. Linearity is ±0.2%/FS at most, with a ripple of 250 mVp-p or less at 500 r/min.
Pulse Output: Rectangular waveform with a pulse width of approximately 2 ms, outputting 1 pulse per 2 revolutions (1 pulse per revolution available as an option). Hi level voltage is at least 4.5 V, and Lo level is up to 0.5 V.

Compatible Detectors: The SE-1620 is compatible with various detectors, including IP-292, IP-296, IP-3100, OM-200, VP-202, and LG-916, each designed for specific applications such as primary or secondary side cable detection, high sensitivity, or photoelectric reflection.

Accessories: Includes an analog output cable, pulse output cable, power cable, and a user manual.

Additional Information: The tachometer is suitable for both on-vehicle and bench-type applications, with isolated inputs, outputs, and power supply to ensure superior noise resistance and stability.
