▲ Overview GZJY-3B-type series is the highest penetration rate in GZJY speed of standard equipment, medium-sized power plants in the country have more than 85% of this type of device configuration. GZJY-3B type (Ⅴ) in addition to retaining GZJY-3B-type basic operations, adds support for several types of active speed sensor voltage drive of choice, all kinds of speed sensor signal precision measurement can access, configure universal probe holder can install various thread sizes or non-threaded sensor ▲ Features 1 Digital speed setting 2 it can be used to test speed, reverse protection and overspeed protection and other instruments and speed speed measuring system. 3 configure attachment complete, photoelectric or mechanical, hand-held, contact or non-contact tachometer, etc. for verification. 4 configurable universal probe holder can be installed multiple sensors, covering a variety of thread sizes of sensor or non-threaded sensor, particularly suitable for a variety of magnetic-electric, magnetoresistive, Hall, eddy current check speed sensor. 5 configuration for all types of aviation-specific accessories may tachometer (models GZ-1, GZ-2, GZ-8A, GZT-1, GZT-2, A10, T-45, etc.), marine tachometer, engine tachometer check. 6 can output standard electrical source, the secondary speed measurement instrument 7 is arranged separately check the speed sensor signal input interface, in the absence of secondary instrument cases, separate speed sensor check (for active speed Sensors offers several types of voltage drive) 8 suitable for medium-sized enterprises and municipal measurement department of speed measurement standard equipment ▲ The main technical indicators 1 speed range: 20 ~ 6600 r / min 2 Speed ??uncertainty: 3 × 10-4 3 Speed ??stability: 1 × 10-4 4 timebase performance: Power accuracy 5 × 10-6 May 5 × 10-6 stability timebase frequency 10 MHz 5 Speed ??Resolution: 0.1 (20 ~ 600 r / min) 1 (600 ~ 6600 r / min) 6 standard electrical signal output: Frequency range 2 ~ 9999 Hz, accuracy of 1 × 10-5, square-wave amplitude of 12V 7 can output DC voltage: ± 5V, ± 12V, ± 24V 8 access outside the test signal required range: 1 ~ 9999 Hz, the amplitude greater than 0.5V 9 chainring: involute type, number of teeth 60, modulo 2, the diameter of 124mm (any number of teeth may be designed according to user requirements specifications of the various chainring) 10 Mounting thread: There are 12 kinds of thread size on the sensor mounting plate: Metric: M10 × 1, M12 × 1, M14 × 1, M16 × 1, M18 × 1, M16 × 1.5, M18 × 1.5 , M20 × 1.5, M22 × 1.5 Inch: 1 / 4-40,3 / 8-24,5 / 8-1811 Total Power: ≤300 W
