Radwag AGV-8 1000.5Y Automatic Comparator for Determination of Mass standard's Density and Volume

Character communication protocol is designed for communication between RADWAG balance and external d (more)evice via RS232, Ethernet or Wi-Fi* interfaces. The protocol consists of commands sent from the external device to the balance and responses sent from the balance to the device. Responses are sent from the balance each time a command is received as a response to the command. The commands that make up the communication protocol allow you to obtain information about the status of the balance and ways to influence its operation, for example, they allow you to receive weighing results from the balance, control the display, etc.

Application: Mass comparator AKM-2 series featuring automatic mass loader enables automatic determin (more)ation of mass deviations of a single weight in a single cycle. The system of automatic mass comparator is commonly applicable in mass measuring laboratories, and particularly in certification units for weights classes E, F and M. Design and functionality: The supervising part of a mass comparator is a digital module which cooperates with a controller of instrument’s mechanical components. The automatic mass loader features a basis with self-centring fields, a robot and a steel body. The digital module and the robot are located in mass comparator’s weighing chamber. The loading robot is controlled by the computer’s controller. The instrument is operated by means of digital display which is plugged to mass comparator’s controller. Lengthwise shift of the loading robot with weights is carried out automatically using solenoid actuators. Additional software functions enable loading and taking off the weights, data processing and storing, and data export to instrument’s memory.

RADWAG-manufactured AVK-1000 automatic vacuum mass comparator is intended for national metrological  (more)institutes that transfer and maintain the national reference mass standard of 1 kg. The comparator is intended for weighing mass standards and silicone spheres of 100 mm diameter. It enables comparison of up to 6 prototypes of max 1kg mass. The repeatability of the process is of 0.3 µg and readability of d = 0.1 µg. A specially designed vacuum chamber enables carrying out measurements in a vacuum of 10-6 mbar capacity or in atmosphere containing noble gases. AVK-1000 is equipped with suspended weighing pan that eliminates eccentricity errors. Standard version of the mass comparator features thermo-hygro-barometer for testing ambient conditions with great accuracy: pressure of 0.001hPa, humidity of 0.01% and temperature of 0.001 °C. The comparator is also equipped with high quality vacuum gauge. The AVK-1000 vacuum mass comparator can be equipped with the LOAD LOCK system for carrying mass standards. The system enables switching or adding artefacts without changing the atmosphere inside the main chamber. With the use of a special chamber for mass standards switching the whole process is 90% shorter. During mass standards replacement carried out without the use of the LOAD LOCK system, the air enters the main chamber of the mass comparator. After each opening of the chamber it is necessary to pump the air out in order to obtain required vacuum value. The vacuum mass comparator needs approx. 48 hours in order to obtain vacuum that ensures measurement repeatability. The LOAD LOCK is equipped with a high-efficiency pump system, the time of pumping the air out in order to enable opening of the valve of the main chamber is significantly shortened. The stabilization of the main chamber after replacing/adding the mass standard and closing the valve connecting the main chamber and the LOAD LOCK system takes 5 hours. The high-quality vacuum gauges enable monitoring and comparing the vacuum value in order to determine the moment when opening the valve again and replacing the mass standard is available. A specially designed viewfinder enables monitoring of the process. The LOAD LOCK enables switching objects of dimensions adapted to the AVK-1000 mass comparator: cylindrical mass standards of 22-95 mm diameter and silicone spheres of 40-100 mm diameter. Supplementing the AVK-1000 vacuum mass comparator with LOAD LOCK system significantly improves the comparison performance.

The new RMC 20000.5Y robotic mass comparator guarantees the utmost repeatability within 1 kg - 20 kg (more) range with the readability of 100 µg. Fully Automated Process of Robotic Comparison of Mass Standards Opening of the weighing chamber in the course of measurements generates air drafts and changes environmental conditions inside the chamber, this causes a great increase in dispersion. The new line of robotic mass comparators eliminates the above problem. It has been solved due to a combination of the robotic mass comparator features with the characteristics of the automatic machines. This innovative approach has improved comparison result repeatability by 100% in relation to standard solutions applied worldwide. A Robot and an Automatic Machine in One RMC 20000.5Y mass comparator combines features of robotic and automatic mass comparators. Thanks to such an innovative combination it is possible to: eliminate air drafts and ground vibrations, maintain stable environmental conditions inside the weighing chamber, prolong life cycle of the robotic system, shorten duration of mass standard comparison, reduce noise. Function of Automatic Mass Standard Dissemination RMCM-5 mass comparator facilitates a complete dissemination process. This is possible thanks to use of the intermediate mass standard magazine, which significantly shortens comparison duration and reduces wear and tear of the transport robot. Real-Time Measurement of Ambient Conditions The new RMC 20000.5Y mass comparator has been equipped with a top-class thermo-hygro-barometer enabling real-time control of ambient conditions in four locations, among many in the weighing chamber and mass standard magazine. Thermo-hygro-barometers are highly precise devices measuring pressure with the readability of 0.001 hPa, humidity of 0.01 %, and temperature of 0.001 °C. Reliability of ambient conditions measurement carried out using the thermo-hygro-barometer is confirmed by a calibration certificate. Universal Magazine Insert Design Mass standard magazine features 10 positions. The RMC 20000.5Y enables comparison of weights of all shapes compliant with OIML recommendations, using just one universal insert. Remote, real-time preview of comparison process is possible thanks to a video camera. Transport Arm With use of the automatic mass comparator, the transport arm remains inactive in the course of comparison, this eliminates air drafts and vibrations, considerably shortens comparison, and reduces noise emission. The transport arm of the RMC 20000.5Y mass comparator is used only to transfer the mass standards, it is out of operation within the comparison process. Ejectable mass standards magazine For the user's convenience, the magazine slides out of the robot's footprint at the time of arming and allows weights to be applied very easily, then positions itself automatically when retracted. Optional Equipment Additional equipment includes a video camera enabling remote preview of comparison process in real time (Internet access required), and RMCS software. The RMCS allows unrestricted monitoring of the comparison process.
