XJP-42A / B is a panel-mount four-digit display of guns. Using single-chip computer, small size, light weight, shape a clear, easy to install. Input signal using optical coupling, a better anti-interference. When using LJ or 3SG series proximity switch for speed sensor only requires the measured shaft with a metal protrusion can be non-contact speed measurement. With factory SZHG-01 Hall-effect speed sensors for contact speed measurement. Another feature is the instrument the number of guns in general were not quite ± 1 digit of the additional measurement error, it is suitable to measure low-speed situations. XJP-42A is a general purpose gun, measurement unit is r / min. XJP-42B is a special gun, compared with XJP-42A multi-step T = k / n op, k made by the user, measurement unit is the min / r. The instrument used for low-speed measurement, the sensor cable lengths up to 50m. Continuous use, suitable for industrial power equipment field measurement speed.
