JYD-L series ultrasonic cell grinderDetailed product description：

Product Usage
The JYD-L series ultrasonic cell grinder is a high-end product of the JYD series, which adds timing control function, combination program function, and automatic limit function of ultrasonic output power. It adopts a large Chinese display LCD screen and a popular vertical structure at home and abroad, and is designed with RS-232C standard interface for computer communication. Equipped with a fault self checking software package and specific state setting function, users can easily perform various working state operations, making the ultrasonic cell grinder more comprehensive, convenient to use, and reliable in performance.
Advanced technology from Germany and upgraded products of domestic ultrasonic cell pulverizers

The JYD-L series ultrasonic cell grinder has the following functions and characteristics:
Scheduled work procedure:
Ten sets of conventional work programs and one set of combination programs can be pre-set, P0-P4 is the counting mode work program, P5-P9 is the timing mode work program, and Pn is the combination program; A combination program can consist of up to ten sets of regular programs, and can choose between cyclic or non cyclic working modes.
Automatic limit of ultrasonic output power:
Within the set window time, the maximum power limit value can be sampled through power detection. When the ultrasound output exceeds the limit power value, the power limit adjustment will be automatically performed to ensure that the ultrasound power does not increase over time during long-term operation.
Automatic frequency tracking of phase-locked loop:
Equipped with phase-locked loop frequency automatic tracking function. Automatic frequency tracking range: 20-25KHz.
Automatic detection and alarm of work status:
It can automatically detect and alarm machine faults, and provide automatic protection and alarm for overheating.
Computer data acquisition and communication:
Comes with a built-in communication program. Remote data collection and monitoring can be achieved by connecting to a computer through a standard RS-232C interface.
The main components of the product include ultrasonic generators and transducer components.

1 Ultrasonic generator:
Working principle: This machine adopts microcontroller control technology and phase-locked loop frequency automatic tracking. Data and control working status can be set through simple keyboard operation. The oscillation frequency of the power amplifier and transducer is phase sampled to enable the phase-locked loop to achieve automatic frequency tracking. The power detection and temperature measurement circuit enables the microcontroller to achieve automatic adjustment of ultrasonic transmission power exceeding the limit, as well as over temperature protection and alarm functions.
2 transducer components:
The transducer component is mainly composed of a transducer and a variable amplitude rod.
3 separate speakers:
It can effectively reduce the noise emitted during the work process and keep the laboratory quiet.
