TLBPROFI - Profibus DP Weight Transmitters

Product description:

TLBPROFI by Laumas is a complete, calibratable Weighing Instrument  Thanks to its new generation electronics, weights can be measured very fast and with extreme accuracy. Measuring is not affected by mechanical or EMI disturbances thanks to sophisticated analog and digital filters.TLBPROFI has an integrated Profibus DP port so it can be easily integrated in a Profibus DP network for AUTOMATIC AND NON-AUTOMATIC WEIGHING APPLICATIONS, for example for:· production of mixtures· filling· loadingmeasuring  filling levels in storage silo · monitoring crane loads· measuring conveyor belt loads· overload protection for industrial lifts· multihead weighers· dynamic weigh systems· batching systems· force measurement systems

TLBPROFI can be used for all weighing applications where there is a Siemens Simatic S7 PLC, in place of Siemens SIWAREX weighing electronics series. TLBPROFI is a modular Profibus DP slave so the PLC programmer can configure only the modules he needs in every application.  TLBPROFI values can be read and written directly in PE or PI Profibus DP peripheral variables.The new Laumas weight transmitter series has been created using the most advanced electronic components: the 24-bit 4800 Hz analogue-digital converter can sample at 1,000,000 intervals with an acquisition frequency of 300 Hz. Fast weight reading (up to 300Hz)

Thanks to its slim form (only 22mm wide!), you can mount many TLBPROFI units on Omega DIN Rail in a very little space . TLBPROFI has an integrated display and 4 keys for easily configuring, testing, weighing verifying and programming. TLBPROFI can be used in both following ways: 1. you can use TLBPROFI to read the load cells signal and send weight counts (up to 1.000.000) to the PLC and proceed with all the calibrations (zero, sample weight verify, net visualization…) on the PLC. 2. you can calibrate the weighing system directly on TLBPROFI (with instrument display and keys or via Profibus DP commands) and send to the PLC the calibrated weight. In this case PLC can also send commands to TLBPROFI, e.g. Net visualization, Semiautomatic Zero, etc.

TLBPROFI is CE-M approvable and it has been approved according to 2009/23/EC; OIML R76:2006; EN45501:1992 TLBPROFI has an optional memory alibi that can store up to 85,000 weighings (Gross Weight, Net Weight, Tare, Predetermined Tare). The memory can be accessed via Profibus DP commands from the PLC or directly, so to realize a complete traceability of weighings also in legal applications for trade according to 2009/23/EC; OIML R76:2006; EN45501:1992. TLBPROFI  has also 2 integrated digital inputs and 3 integrated digital relay outputs that can be read and written by Siemens Simatic S7 PLC so to realize a little I/O unit.TLBPROFI  has also 1 RS485 Modbus RTU configurable serial port.
