The PT110LC, PT111LC and PT112LC are DIN rail mounted micro-controller 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).

The PT110LC is good for weighing where the weight of the item does not change quickly, such as silos, tanks and scales.
Additionally the PT111LC has 2 set point relay outputs for process control or hi or low alarms, more analogue output options and and an RS232 port for configuration via PC and AzCom software.

The PT112LC is a high speed version of the PT111LC with 6 wire load cell connection and remote zero input with fast response and could also be used for filling, batching and checkweighing. The PT112LC-MB also has Modbus and ±10V output.

  • Minimized zero and span drifts due to use of micro-controller 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 pre-calibrated to 0–10 V and to 4–20 mA analog output ranges for 0–2mV/V load cell signal range as a factory default.
  • Factory matching facilitates swap out without PLC readjustment.

  • Inputs most strain gauge bridge devices (load and pressure).
  • Analogue output, selectable 0-10V or 4-20mA.
PT111LCfeatures extra to PT110LC
  • Additional output options 0-5V, 0-20mA.
  • 2 set point relay outputs.
  • 3 filter settings.
  • Programmable via PC, PLC and AzCom software.
  • Calibration without calibration weights (using load cell mV/V entry).
PT112LCfeatures extra to PT111LC
  • High speed conversion, up to 800 conversions per second. Step response as fast as 25ms.
  • Adjustable response for fast changing processes with 9 step filter.
  • Low drift of <0.005% FSO/ºC.
  • Increased excitation for larger installations, 8x 350Ω.
  • 6 wire load cell connection for accuracy.
  • Opto-isolated input for zeroing.
  • Modbus and ±10V output for the PT112LC-MB
