Type MBZ880A quantitative packaging controller is designed for cement packing machine with automatic quantitative control of microcomputer, using machine microprocessor, high precision A/D conversion technology, the use of high frequency, strong resistance to electromagnetic interference ability of metal shell, and strictly carry out the advanced production craft, 72 hours aging test, test specification, make sure it has A long working reliability and stability. Can be widely used in a variety of quantitative packaging weighing control equipment.
1. It is used in 51 series single chip, high speed A/D conversion technology, high resolution and high intelligence degree.
2. Metal shell, special sensor, digital filtering, nonlinear compensation, one-button return to zero software and hardware technologies improve the anti-interference ability and linearity of the instrument, and eliminate the zero drift of the system.
3. Full digital keyboard, simple calibration method.
4, with a variety of display Windows, intuitive display given, running, zero weight and other parameters, easy to operate.
5. LED indication of working status.
6. Power off protection and packet number function.
1. Supply voltage: AC220V/50Hz± 10%
2. Operating temperature: -10℃~ + 45℃
3. Relative humidity: ≤ 85%
4. Power consumption 10W, fuse 500mA
5. A/D conversion rate is 5/500,000
6. The range is 2-30mA
7, pressure sensor bridge 8 v (350 Ω sensor)
8. Overload range: 120%
1. The controller can be fixed in three ways (back-mounted, back-mounted and bottom-mounted), and can be installed at the position with small vibration source according to the field conditions.
2. The sensor is a high-sensitivity device, which should be kept vertical during installation, and all parts should be kept firm, without looseness or displacement. The sensor should have certain pre-tension, and the lead wire of the sensor should not be too tight or too loose, and there should be no sticking and collision around the sensor.
3, the mechanical part of the body should be firm, can not be loose, the body is relatively suspended, try to avoid the contact between the body and non-body.
