Without Product Effect Blanking-Out

The new generation in metal detecting technology
The product effect blanking out of the detectors was refined further. Especially the electric conductivity of the black plastic products in influencing the measurement signals of the metal detector. Only if these signals are precisely characterisized and filtered, even the smallest metallic particles can be found in such products. This precision of product effect blanking out is achieved by digial sensor processor technology of the latest generation.

In practical use, settings of metal detectors often need to be checked quickly and reliably during running applications. That is why great value was attached to user friendly operation.

The software is self-explanatory and leads the operator step by step through the setup means. A LED bar indicates the quantity of the product effect and the metal detection threshold. The unit is operated by means of a foil keyboard at the outer side of the control cabinent.

The tranducer amplification is automatically adpating to the product. In case that products with both very great and very low product effects are scanned be one and the smae metal dtector, the unit will automatically select the optimum amplification.

- Precise metal detection on highest level - Large Sensor Enclosures
The MPULSe digital electronic unit supplies excellent and reliable metal search results during operation. Shield the device effectively against electromagnetic interference fields and concentrate the measuring field in the sensor coil.
Digital Balance Control Highest ensurance
Keeps the detector coil always at the optimum working point and compensates temperature and humidity influences. The extra study sensor construction is designed to operate under extreme conditions which cause others to fail.
Digital Frequency Control Intuitive Operation
Guarantees constantly stable coil frequencies and phases. The display shows only the information that is really necessary. Reduction to the essential makes operation clear and transparent.
Digital Noise Filters  
Eliminate undesired signals.  
Digital product effect blanking out  
Ensures optimum recognition even in wet products. Product effects are blanked out and compensated in an intelligent way [tracking]  
Network options Training Function
Ethernet, WLAN, Rs485 or RS282 Provides simple and quick learning of 3 product characterisitics for product effect compensation.
  Password protection
  Against unauthorised operation.
- Operation Safety -  
Maintenance Free Timer
The MESEP digitalized circuitry ensures many years of reliable performance. [Pulse length, pulse delay] to control separating systems in a synchronised way.
Automatic Self-Control Acquisition of internal operation data
Possible functional defects of the device are displayed at a separate output contact. Events such as metal detections or parameter settings are stored including date and time and can be read on the display or exported via serial interface.

Communications of MPULSE metal detectors with one central point PC.
After installation of the windows M-Pulse software important informations of the metal detectors will memorize in an access data bank full automatically. With M-Pulse control you can install a quality managment system according HACCP and IFS rules. With the software you have the actual status of all connected units. A manual documentation needs to much time and costs a lot of money. M-Pulse control make this job full automatic for you.

M-Pulse control informs about

  • time and number of metal detection
  • all important adjustments
  • status of all devices
  • performance test
  • fault messages
  • actual product name and numbers.
M-Pulse simple and intuitional System requirement on the PC
The integration in the familiar surroundings of windows will make the using very easy and simple. All datas of each connected devices you see with one mouse kick. With the special interval function the end user can select at time interval and print all activities during this duration. With M-Pulse you can prove the correct and reliable function of the detectors during the production of a special product charge. M-Pulse is the powerful "firewall" in a case of a liability claim.
