DT-2235B+ Overview
DT-2235B+ contact rpm digital tachometer is used for speed testing of rotors such as various engines, motors, speed control devices and wire speed tests of various conveyor belts. It is used in the speed debugging of various devices such as aircraft, ships, EMUs, automobiles, model aircraft, toys, etc.; and the surface speed debugging of assembly lines and transmission dials.
The DT-2235B+ is a contact tachometer. The operator presses a rubber tip against a shaft centre, or a wheel against a moving belt or roller, to read speed directly. Beyond rotational speed of 0.5~19,999 RPM, it reads surface (line) speed of 0.05~1999.9 m/min and totals measured length up to 99999 m. Accuracy is ±(0.05%+1).
Key features
- Contact RPM 0.5~19,999 RPM
- Surface speed 0.05~1999.9 m/min, resolution 0.01 m/min below 100 m/min
- Measured length 0.05~99999 m, resolution 0.02 m
- Accuracy ±(0.05%+1), auto ranging, 99999 max display
- Max/Min/Last value memory; sampling 0.8s above 60 RPM
- 4×AA batteries, approx. 45mA
Applications
Shaft speed on motors and gearboxes, line speed of conveyor belts, assembly lines and transmission rollers, and measuring the length of material passing a roller.
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.
