Shanghai Speed Meter Factory Speed Digital Display Instrument

Shanghai Speed Meter Factory Speed Digital Display InstrumentProduct Introduction:

XJP-42BSpeed digital display instrument，It is a panel mounted four digit display speedometertableAdopting a single-chip microcomputer, it has small size, light weight, clear character shape, and easy installation. The signal input terminal adopts photoelectric coupling method, which has good anti-interference performance. When using LJ or 3SG series proximity switches as speed sensors, non-contact speed measurement only requires a metal protrusion on the measured shaft. Equipped with our SZHG-01 Hall effect speed sensor, it can perform contact speed measurement.

Another characteristic of the instrument is that it does not have an additional measurement error of ± 1 digit compared to typical digital speedometers, making it suitable for measuring low-speed situations. XJP-421A is a universal speedometer with a measurement unit of r/min. XJP-42B is a speedometer, which has an additional T=k/n operation compared to XJP-42A. k is proposed by the user and the measurement unit is min/r. This instrument is used for low-speed measurement, and the transmission line length of the sensor can reach 50m. It can be used continuously and is suitable for measuring the speed of power equipment on industrial sites.
