Control Devices for Metering and Batching Equipment
TenzoTEK-03 Metering Converter
TenzoTEK-03 metering converter is aimed for static weighing within truck, railway, platform, hopper scales as well as batching for various companies: metallurgy, mining, fuel and power, chemical etc. as a part of automated control systems (PCS) within flow metering systems.
Operation Features
- Indicating zero weighing on 6-digit seven segment display
- Indicating gross weight, net weight and tare
- Zero weight alignment
- Expanded temperature ranges
- Storing and displaying outcomes of several weighing sessions
- Monitoring the sensor regarding of power loss / short circuit, overcurrent of one parallel connected sensor (number of sensors is setup by the operator)

TenzoTEK-03 Performs the Following Functions as per In-Built Algorithm:
- Unit indication: ">0<", "gross weight", "net weight", "stabilization mode", weight metering units "kg/t", exceeding weight limit "excessive weight"
- Conversion of analogue signal from strain measuring bridge into current weight value
- Measuring channel calibration
- Measuring channel linearization
- Filtering signal from measuring channel within setup ranges
- Measuring current weight
- Zero setting and scales tare offset
- Exchanging data with the upper level computer through RS-485, RS-232 interfaces, protocol Modbus RTU
- keeping archive data up to 100 last measurement sessions on measuring results, giving number number, date and time of weight measurement

Design
TenzoTEK-03 is designed as a stationary unit in plastic casing and it consists of the following modules:
- metering module, aimed for metering the signals from the sensor, processing it and transferring weight data to the upper level computer
- display and keyboard, aimed to display weight data, emergency, selection and setup of parameters
- connection module aimed to connect the sensor, power supply and the upper level computer
Versions of TenzoTEK-03:
- TenzoTEK-03-I - complete version
- TenzoTEK-03-R - with no display and keyboard, operation only through RS-232/485 interface
Dimensions: 235mm×160mm×72mm (length, width, height)
Weight of TenzoTEK-03 without package: does not exceed 4 kg
