PT Ltd Innovative Measurement Electronics PT110LC, PT111LCANALOGUE LOAD CELL CONDITIONERS ... A$o>ie Signature Series! The PT110LC and PT111LC are DIN rail mounted microcontroller based analogue load cell transmitters. They have very high accuracy and long term stability with advanced design. Using an up to-date delta-sigma ADC and 16 bit DAC to achieve higher speed and accuracy these instruments give the system designers a lot of advantages towards increasing system reliability and reducing the installation and service times. All instruments’ analogue outputs are matched during production to simplify calibration with a PLC and to simplify exchanging the instrument without recalibration in service when initial adjustment has been performed in the PLC. There are 8 position rotary switches and annunciator LEDs on the front panel of the instruments. The upper rotary switch adjusts the empty scale’s analogue output level (zero adjustment) and the lower rotary switch adjusts the gain of the instrument (span). Additionally the PT111LC has 2 set point relay outputs for process control or alarms, more analogue output options and and an RS232 port for configuration via PC and AzCom software. Features • Minimized zero and span drifts due to use of microcontroller technology. • High accuracy, very low temperature drift 24 bit ADC and 16 bit DAC converters. • Compact DIN rail mounting, size is only 22.5mm * 99mm from the front. • Long term stability and low temperature drifts eliminate the need for frequent readjustment. • Digital adaptive anti-vibration filter to minimize errors from environmental vibrations. • All instrument have been precalibrated to 0-10 V and to 4-20 mA analogue output ranges for 02mV/V load cell signal range as a factory default. • Factory matching facilitates swap out without PLC readjustment. Integration • Analogue output ◦ 0-10V PT111LC extra features • Additional output options 0-5V, 0-20mA. • 2 set point relay outputs. • Programmable via PC, PLC and AzCom software. • Calibration without calibration weights (using load cell mV/V entry)
