DT-2234B Overview
DT-2234B non-contact photo rpm tachometer is used for touchless speed testing of rotors such as various engines, motors, speed control devices, etc. It is used in the debugging of various devices such as aircraft, ships, emmobiles, automobiles, model aircraft, and toys.
The DT-2234B is a handheld non-contact tachometer that reads rotational speed from a reflective mark using an LED photoelectric beam. Maintenance technicians and motor repair shops use it on running equipment without touching the shaft. It covers 2.5~99,999 RPM at ±(0.05%+1), with a working distance of 50~250mm.
Key features
- LED photoelectric, 2.5~99,999 RPM
- Detecting distance 50~250mm (2~10ft)
- Accuracy ±(0.05%+1), auto ranging, 99999 max display
- Resolution 0.1 RPM below 1000 RPM, 1 RPM above
- 6MHz quartz crystal time base, 10×10⁻⁶ (0℃~50℃)
- Max/Min/Last value memory; sampling 0.8s above 60 RPM; 4×AA batteries
Applications
Speed checks on motors, engines, fans, pumps and speed control devices, and RPM set-up during maintenance of vehicles, ships, aircraft, model aircraft and production machinery.
Choosing within the series
In the DT-22 series, the DT-2234B is LED photoelectric (50~250mm), the DT-2234C is laser (50~500mm), the DT-2235B+ is contact only with surface speed and length, and the DT-2236C combines contact and laser. All DT-22 models run on 4×AA batteries only. The DT-62 series (DT-6234B/C, DT-6235B, DT-6236B/C) adds an external power supply option, and its contact models store 96 data sets.
